A taxonomic study of bacteria isolated from grasses: a proposed new species Pseudomonas graminis sp. nov. (1/2130)

The taxonomic position of a yellow-pigmented group of bacteria, isolated from the phyllosphere of grasses was investigated. Results obtained from restriction analysis of amplified 16S rDNA with seven endonucleases (CfoI, HaeIII, AluI, HinfI, MspI, Sau3A and ScrFI) showed identical restriction patterns for each enzyme of all isolates studied, which suggests that all strains belong to the same species. The grass isolates displayed the characteristics of the genus Pseudomonas. They were Gram-negative, aerobic and rod-shaped with polar flagella. Isolates were catalase-positive and oxidase-negative, and unable to oxidize or ferment glucose with the production of acid. The isolates did not reduce nitrate to nitrite but were able to utilize a wide range of compounds individually as a sole carbon source, with preference being given to the utilization of monosaccharides. The disaccharides tested were not utilized as substrates. The DNA base compositions of the tested strains ranged from 60 to 61 mol% G+C. The major isoprenoid quinone of each was ubiquinone Q-9 and hydroxy fatty acids were represented by 3-hydroxydodecanoic acid and 2-hydroxydodecanoic acid. Comparison of 16S rDNA sequences showed that the bacteria were members of the genus Pseudomonas, with similarity values between 91.5 and 97.7%. DNA-DNA hybridization studies with closely related neighbours revealed a low level of homology (< 27%), indicating that the isolates represent an individual species. On the basis of phenotypic and phylogenetic analyses a new species, Pseudomonas graminis sp. nov. (type strain DSM 11363T), is proposed.  (+info)

Evolutionary dynamics of Ty1-copia group retrotransposons in grass shown by reverse transcriptase domain analysis. (2/2130)

The evolutionary dynamics of Ty1-copia group retrotransposons in grass were examined by reverse transcriptase (RT) domain analysis. Twenty-three rice RT sequences were newly determined for this report. Phylogenetic analysis of 177 RT sequences, mostly derived from wheat, rice, and, maize, showed four distinct families, which were designated G1, G2, G3, and G4. Three of these families have elements obtained from distantly related species, indicative of origins prior to the radiation of grass species. Results of Southern hybridization and detailed comparisons between the wheat and rice sequences indicated that each of the families had undergone a distinct pattern of evolution. Multiple families appear to have evolved in parallel in a host species. Analyses of synonymous and nonsynonymous substitutions suggested that there is a low percentage of elements carrying functional RT domains in the G4 family, indicating that the production of new G4 elements has been controlled by a small number of elements carrying functional RT domains.  (+info)

Identification of Epichloe endophytes in planta by a microsatellite-based PCR fingerprinting assay with automated analysis. (3/2130)

Epichloe endophytes are a group of filamentous fungi that include both sexual (Epichloe) and asexual (Neotyphodium) species. As a group they are genetically diverse and form both antagonistic and mutualistic associations with temperate grasses. We report here on the development of a microsatellite-based PCR system for fingerprinting this group of fungi with template isolated from either culture or infected plant material. M13mp19 partial genomic libraries were constructed for size-fractionated genomic DNA from two endophyte strains. These libraries were screened with a mixture of DIG-labeled dinucleotide and trinucleotide repeat probes. Positive clones were sequenced, and nine unique microsatellite loci were identified. An additional microsatellite was serendipitously identified in the 3' untranscribed region of the 3-hydroxy-3-methylglutaryl coenzyme A (HMG CoA) reductase gene from N. lolii Lp19. Primers were designed for each locus and a panel of endophytes, from different taxonomic groupings, was screened to determine the degree of polymorphism. On the basis of these results a multiplex assay was developed for strain identification with fluorescently labeled primers for five of these loci. Using this system the size of the products amplified can be precisely determined by automated analysis, and an allele profile for each strain can be readily generated. The assay was shown to resolve endophyte groupings to the level of known isozyme phenotype groupings. In a blind test the assay was used successfully to identify a set of endophytes in planta. A reference database of allele sizes has been established for the panel of endophytes examined, and this will be expanded as new strains are analyzed.  (+info)

Postweaning performance of calves from Angus, Brahman, and reciprocal-cross cows grazing endophyte-infected tall fescue or common bermudagrass. (4/2130)

Data from 403 Polled Hereford-sired calves from Angus, Brahman, and reciprocal-cross cows were used to evaluate the effects of preweaning forage environment on postweaning performance. Calves were spring-born in 1991 to 1994 and managed on either endophyte-infected tall fescue (E+) or common bermudagrass (BG) during the preweaning phase. After weaning, calves were shipped to the Grazinglands Research Laboratory, El Reno, OK and stratified to one of two winter stocker treatments by breed and preweaning forage; stocker treatments were winter wheat pasture (WW) or native range plus supplemental CP (NR). Each stocker treatment was terminated in March, calves grazed cool-season grasses, and calves were then moved to a feedlot phase in June. In the feedlot phase, calves were fed to approximately 10 mm fat over the 12th rib and averaged approximately 115 d on feed. When finished, calves were weighed and shipped to Amarillo, TX for slaughter. Averaged over calf breed group, calves from E+ gained faster during the stocker phase (P<.10), had lighter starting and finished weights on feed (P< .01), lighter carcass weights (P<.01), and smaller longissimus muscle areas (P<.05) than calves from BG. Calves from E+ were similar to calves from BG in feedlot ADG, percentage kidney, heart, and pelvic fat, fat thickness over 12th rib, yield grade, marbling score, and dressing percentage. Maternal heterosis was larger in calves from E+ for starting weight on feed (P<.01), finished weight (P<.10), and carcass weight (P<.16). These data suggest that few carryover effects from tall fescue preweaning environments exist, other than lighter, but acceptable, weights through slaughter. These data further suggest that the tolerance to E+ in calves from reciprocal-cross cows, expressed in weaning weights, moderated postweaning weight differences between E+ and BG compared to similar comparisons in calves from purebred cows.  (+info)

The mechanism of rhythmic ethylene production in sorghum. The role of phytochrome B and simulated shading. (5/2130)

Mutant sorghum (Sorghum bicolor [L.] Moench) deficient in functional phytochrome B exhibits reduced photoperiodic sensitivity and constitutively expresses a shade-avoidance phenotype. Under relatively bright, high red:far-red light, ethylene production by seedlings of wild-type and phytochrome B-mutant cultivars progresses through cycles in a circadian rhythm; however, the phytochrome B mutant produces ethylene peaks with approximately 10 times the amplitude of the wild type. Time-course northern blots show that the mutant's abundance of the 1-aminocyclopropane-1-carboxylic acid (ACC) oxidase mRNA SbACO2 is cyclic and is commensurate with ethylene production, and that ACC oxidase activity follows the same pattern. Both SbACO2 abundance and ACC oxidase activity in the wild-type plant are very low under this regimen. ACC levels in the two cultivars did not demonstrate fluctuations coincident with the ethylene produced. Simulated shading caused the wild-type plant to mimic the phenotype of the mutant and to produce high amplitude rhythms of ethylene evolution. The circadian feature of the ethylene cycle is conditionally present in the mutant and absent in the wild-type plant under simulated shading. SbACO2 abundance in both cultivars demonstrates a high-amplitude diurnal cycle under these conditions; however, ACC oxidase activity, although elevated, does not exhibit a clear rhythm correlated with ethylene production. ACC levels in both cultivars show fluctuations corresponding to the ethylene rhythm previously observed. It appears that at least two separate mechanisms may be involved in generating high-amplitude ethylene rhythms in sorghum, one in response to the loss of phytochrome B function and another in response to shading.  (+info)

Quantifying the risks of TB infection to cattle posed by badger excreta. (6/2130)

Despite strong circumstantial evidence to suggest that the main route of TB transmission from badgers to cattle is via contaminated badger excreta, it is unclear whether the associated risks are high enough to account for the prevalence of the disease in south-west England. To decide whether this was a viable route of transmission, cattle contact with badger excreta was investigated using a deterministic approach to quantify the risks to cattle posed by badger excreta. Levels of investigative and grazing contacts between cattle and badger urine and faeces could each account for the disease prevalence in south-west England. An infection probability of 3.7 x 10(-4) per bite from pasture contaminated with badger urine infected with Mycobacterium bovis could account for the prevalence of TB in cattle in south-west England. Infection probabilities of 6.9 x 10(-7) per investigation and 1.1 x 10(-7) per bite from badger latrines could each account for the prevalence of TB in cattle in the south-west. When considering only the high risk areas of south-west England these bounds fell by a factor of eight. However, badger excreta may still constitute a high level of risk to cattle. The levels of cattle contact with badger excreta are far higher than previously thought, suggesting that it is the probability of infection per given contact with infected badger excreta which has the greater influence on the probability of transmission and not the level of contact. The infection probability per cattle contact with infected badger excreta is in all likelihood extremely low.  (+info)

Fractionation of fiber and crude protein in fresh forages during the spring growth. (7/2130)

The composition of the fiber and CP of alfalfa, bromegrass, and endophyte-free and -infected tall fescue forages was compared during the spring growth from vegetative to reproductive stages. Forages were sampled from April 27 to June 6 in 1994, and from April 27 to June 11 in 1995, with 11 and 12 harvest dates, respectively. Total dietary fiber (TDF) was fractionated into insoluble and soluble fiber (SF). The CP of the forages was fractionated into nonprotein N (A), soluble CP (B1), insoluble CP that was soluble in neutral detergent (B2), CP insoluble in neutral detergent but soluble in acid detergent (B3), and CP insoluble in acid detergent (C). Effects of year, forage species, and harvest dates (day as a covariable) were included in the model. Across harvest dates, alfalfa (A) had lower (P < .01) TDF and higher (P < .01) SF concentrations than grasses (GR) (A: 49.9 and 14.4% and GR: 60.4 and 4.5% [OM basis] for TDF and SF, respectively). Alfalfa had higher (P < .01) CP (20.6% DM) than GR (15.3%). The rate of decrease in CP (% DM) across days was higher (P < .01) for bromegrass (-.4%/d) than for the other forages (-.29%/d). Fraction A (% of CP) was not different (P = .24) among forages (22.5%), but B1 was higher (P < .01) in A (17.1%) than in GR (13.2%). The B2 fraction (% of CP) was higher (P < .01) in A compared with GR (51.6 vs 45.9%, respectively). Alfalfa had lower (P < .01) B3 (3.0% of CP) than bromegrass (18.6%) and tall fescue (13.2%). Fraction C was not different (P = .23) among forages (3.8%). Fractions A, B1, and C (% of CP) did not change (P > .05) across days for all forages. Fraction B2 (% of CP) decreased across days in A (-.21%/d) but was not affected in GR. Fraction B3 (% of CP) increased (P < .05) in A (.1%/d), decreased in endophyte-infected tall fescue (-.20%/d), and did not change (P > .05) in the other forages. Crude protein and fiber composition were affected more by forage species than by maturity. The CP and NDF concentrations were more affected by maturity. Insoluble fractions but not soluble fractions of CP were affected by maturity.  (+info)

Molecular analysis of bacterial community structure and diversity in unimproved and improved upland grass pastures. (8/2130)

Bacterial community structure and diversity in rhizospheres in two types of grassland, distinguished by both plant species and fertilization regimen, were assessed by performing a 16S ribosomal DNA (rDNA) sequence analysis of DNAs extracted from triplicate soil plots. PCR products were cloned, and 45 to 48 clones from each of the six libraries were partially sequenced. Phylogenetic analysis of the resultant 275 clone sequences indicated that there was considerable variation in abundance in replicate unfertilized, unimproved soil samples and fertilized, improved soil samples but that there were no significant differences in the abundance of any phylogenetic group. Several clone sequences were identical in the 16S rDNA region analyzed, and the clones comprised eight pairs of duplicate clones and two sets of triplicate clones. Many clones were found to be most closely related to environmental clones obtained in other studies, although three clones were found to be identical to culturable species in databases. The clones were clustered into operational taxonomic units at a level of sequence similarity of >97% in order to quantify diversity. In all, 34 clusters containing two or more sequences were identified, and the largest group contained nine clones. A number of diversity, dominance, and evenness indices were calculated, and they all indicated that diversity was high, reflecting the low coverage of rDNA libraries achieved. Differences in diversity between sample types were not observed. Collector's curves, however, indicated that there were differences in the underlying community structures; in particular, there was reduced diversity of organisms of the alpha subdivision of the class Proteobacteria (alpha-proteobacteria) in improved soils.  (+info)

The following cool-season grasses are most often used in Maine lawns:. Kentucky bluegrass is the dominant grass type in traditional northern lawns. A blend of three or more varieties of Kentucky bluegrass forms an excellent lawn in a full-sun, well-drained site with moderate-to-high fertility and regular irrigation. Kentucky bluegrass knits together well because it spreads by underground rhizomes. It tolerates cold winter temperatures and heavy wear, making it an excellent athletic field choice. In the heat of summer, it sometimes becomes dormant and turns brown, but it greens up again when temperatures drop. When this grass is over-fertilized or over-watered, it can develop a layer of thatch (dead tissue at the base of the plants) that interferes with water movement and grass growth.. Fine fescues include red fescue, chewings fescue, and hard fescue. They have finer texture than Kentucky bluegrass. They are quite tolerant of dry soils, acid soils, and low fertility, and perform well in shady ...

Along the southern U.S. seashore, the snail, Littoraria irrorata, contributes to the growth of fungi - its favorite food - on marsh grasses. Researchers call that process fungal farming. Laboratory studies have shown that snails are more robust when fed a combination of marsh grass and fungi rather than grass alone.. In surveys conducted along 2,000 kilometers of salt marshes on the southern U.S. shoreline, the researchers observed that the snail, Littoraria irrorata, actively grazes a live salt-marsh cordgrass. As the snail crawls along the grass surface, it scrapes grass tissue with its band of saw-like teeth and creates longitudinal cuts in leaf surfaces, making a much larger meal possible. While it travels, the snail also deposits feces laden with fungal spores and nutrients into the sensitive inner-tissue of the leaf, effectively stimulating and fertilizing fungal crops.. The result of snail grazing on marsh grass surface is an infestation of fungi, a major diet component for the snail, ...

We collected naturally recolonizing Spartina alterniflora (smooth cord grass) from each of three restored sites and one undisturbed reference site in southwestern Louisiana to assess the impact of wetland restoration on genetic diversity. We used amplified fragment length polymorphisms (AFLPs) to produce 94 polymorphic genetic markers, which were used to characterize genetic diversity as average heterozygosity and the proportion of polymorphic loci . Overall our findings indicate that restored populations of S. alterniflora maintain levels of genetic diversity comparable to natural populations, which should provide some measure of resistance against environmental disturbances. Diversity estimates were lowest for the natural reference site ( = 0.1059; = 0.2763), whereas estimates for the three restored sites ranged from = 0.1148 to 0.1256 and = 0.3114 to 0.3202. All sites maintained sufficiently high diversity levels to suggest significant rates of outcrossing. Overall, genetic differentiation among
The Poaceae family is of great importance to human beings since it comprises the cereal grasses which are the main sources for human food and animal feed. With the rapid growth of genomic data from Poaceae members, comparative genomics becomes a convinent method to study genetics of diffierent species. The SSRs (Simple Sequence Repeats) are widely used markers in the studies of Poaceae for their high abundance and stability. In this study, using the genomic sequences of 9 Poaceae species, we detected 11,993,943 SSR loci and developed 6,799,910 SSR primer pairs. The results show that SSRs are distributed on all the genomic elements in grass. Hexamer is the most frequent motif and AT/TA is the most frequent motif in dimer. The abundance of the SSRs has a positive linear relationship with the recombination rate. SSR sequences in the coding regions involve a higher GC content in the Poaceae than that in the other species. SSRs of 70-80 bp in length showed the highest AT/GC base ratio among all of these loci
The Poaceae family is of great importance to human beings since it comprises the cereal grasses which are the main sources for human food and animal feed. With the rapid growth of genomic data from Poaceae members, comparative genomics becomes a convinent method to study genetics of diffierent species. The SSRs (Simple Sequence Repeats) are widely used markers in the studies of Poaceae for their high abundance and stability. In this study, using the genomic sequences of 9 Poaceae species, we detected 11,993,943 SSR loci and developed 6,799,910 SSR primer pairs. The results show that SSRs are distributed on all the genomic elements in grass. Hexamer is the most frequent motif and AT/TA is the most frequent motif in dimer. The abundance of the SSRs has a positive linear relationship with the recombination rate. SSR sequences in the coding regions involve a higher GC content in the Poaceae than that in the other species. SSRs of 70-80 bp in length showed the highest AT/GC base ratio among all of these loci
Description: This perennial grass is about 3-7 tall; it forms a large tuft of leafy culms. The culms are light green to pale reddish green, glabrous, terete, and usually unbranched. Alternate leaves are located primarily along the lower one-half of each culm. The leaf blades are up to 2 long and 1 across; their upper sides are medium green and glabrous, while their lower sides are light green and glabrous. Most leaf blades are arching and rather floppy; larger leaf blades usually have white central veins that are conspicuous. The leaf sheaths are light green to reddish green, glabrous, longitudinally veined, and open. The ligules consist of short white hairs. Each culm terminates in 1-3 floral spikes (rarely up to 5 floral spikes) that are erect to ascending. These spikes are narrowly cylindrical and 4-12 long; their spikelets are sessile or nearly so. Gama Grass is monoecious, producing separate male (staminate) and female (pistillate) florets on the same inflorescence. Spikelets of male ...
Grassland management can modify soil microbial carbon (C)and nitrogen (N)cycling, affecting the resistance to extreme weather events, which are predicted to increase in frequency and magnitude in the near future. However, effects of grassland management on microbial C and N cycling and their responses to extreme weather events, such as droughts and heatwaves, have rarely been tested in a combined approach. We therefore investigated whether grassland management affects microbial C and N cycling responses to drought and temperature manipulation. We collected soils from in situ drought experiments conducted in an extensively managed and an abandoned mountain grassland and incubated them at two temperature levels. We measured microbial respiration and substrate incorporation, as well as gross rates of organic and inorganic N cycling to estimate microbial C and N use efficiencies (CUE and NUE). The managed grassland was characterized by lower microbial biomass, lower fungi to bacteria ratio, and ...
We explored relationships between plant productivity and annual fluxes of nitrogen (N2) and nitrous oxide (N2O) in a tallgrass prairie landscape in central Kansas. Our objective was to develop predictive relationships between these variables that could be used in conjunction with remote sensing information on plant productivity to produce large-area estimates of N gas fluxes. Our hypothesis was that there are inherent relationships between plant productivity and N gas fluxes in tallgrass prairie because both are controlled by water and N availability. The research was carried out as part of a multi-investigator project, the First ISLSCP Field Experiment (FIFE, ISLSCP = International Satellite Land Surface Climatology Program), directed toward the use of remote sensing to characterize land-atmosphere interactions. Fluxes of N2 (denitrification) and N2O were measured using soil core techniques. Estimates of annual flux were produced by temporal extrapolation of measured rates. Annual aboveground ...
Global change is predicted to promote plant invasions world-wide, reducing biodiversity and ecosystem function. Phenotypic plasticity may influence the ability of introduced plant species to invade and dominate extant communities. However, interpreting differences in plasticity can be confounded by phylogenetic differences in morphology and physiology. Here we present a novel case investigating the role of fitness trait values and phenotypic plasticity to global change factors between conspecific lineages of Phragmites australis. We hypothesized that due to observed differences in the competitive success of North American-native and Eurasian-introduced P. australis genotypes, Eurasian-introduced P. australis would exhibit greater fitness in response to global change factors. Plasticity and plant performance to ambient and predicted levels of carbon dioxide and nitrogen pollution were investigated to understand how invasion pressure may change in North America under a realistic global change scenario.

Background/Question/Methods Herbivory is expected to have important effects on grassland plant community structure and biomass. However, the effects of herbivores may be mitigated by plant resource availability, which can influence plant compensatory response and plant defense, and may vary among herbivore taxonomic groups. Although a number of experiments have tested the relative importance and interactive effects of herbivory and plant resource availability in limiting plant biomass, little is known about how different herbivore taxonomic groups contribute to these patterns particularly in terrestrial systems. We tested for the additive or interactive effects of insect and non-bovine mammalian herbivores on plant community structure and biomass in a restored grassland in south-central Kansas. The experiment consisted of ninety-six, 3.5x4 m plots. Mammal access was restricted by fencing while insect abundance was reduced by applying a pyrethroid-based insecticide every two weeks during the ...

The Maritime Dry Grassland Community occurs on low, stable dunes and sand ridges. It also occurs in overwash terraces behind or between dunes in areas subject to inundation by the ocean or partial burial due to wind-blown sand. Frequently, this community transitions into the dune grass community on the ocean side. The dominance of saltmeadow grass readily distinguishes maritime dry grassland from the dune grass community. Under natural conditions this community is influenced by salt spray that retards shrub invasion. Where dunes are naturally protected or have been artificially stabilized, these grasslands can succeed into maritime shrub and possibly to maritime forest with sufficient time. In contrast, the maritime dry grassland may transition from maritime shrub or maritime forest in areas where there is loss of dune protection. In addition to saltmeadow cordgrass, this community may have a moderate to dense herbaceous cover of species such as seaside goldenrod, marsh pink, seaside greenbrier, ...

Miscanthus sinensis, commonly known as Chinese silver grass, Japanese silver grass or eulalia grass, is a clump-forming warm season grass that typically grows to 3-7 tall. It is native to lowlands and lower alpine areas in Japan, Korea and China. It has escaped gardens and naturalized in over 25 states in the Central and Eastern U.S. east of the Mississippi River plus in several western States including Colorado and California. This grass features a dense clump of upward-arching stems and leaves which give it a rounded, fountain-like appearance. Linear leaves (to 3-4 long and 3/8 wide) have tapered tips, serrate margins and whitish to silvery midribs. Foliage often turns attractive shades of yellow to orange by mid-fall before gradually fading to beige-tan for winter. Pink to red flowers in feathery, whisk-like, loose terminal panicles (8-10 long) bloom above the foliage from late August to October. Flower panicles gradually turn beige by mid-fall as the seeds mature. Flower panicles and ...

Cattle producers see more profit when they add legumes to fescue pastures and manage grazing systems properly, says Patrick Davis, University of Missouri Extension livestock specialist.. Fescue remains the hardy mainstay of southwestern Missouri pastures. Adding legumes gives fescue fields more nutritional punch and profit, Davis says. Proper management is key to making grasses and legumes work well together, he says. This begins with management-intensive grazing (MIG).. Under MIG, cattle graze on forage 3 to 8 inches tall. Cattle begin grazing at 8 inches and eat forage down to 3 inches. This is followed by paddock rest until the forage reaches original height. This strategy promotes stronger roots and gives cattle best-quality forage, Davis says. Forage in this range also contains less ergovaline, a toxic alkaloid. The highest concentrations of ergovaline are in the bottom 2 inches of the plant and seed heads.. Add legumes into fescue pastures for other benefits. Pasture quality improves and ...

Crossbred steers (n = 64) were grazed on warm- or cool-season grasses, without or with energy supplementation of wet distillers grains with solubles (WDGS), and were finished on a corn-based diet with or without 35% WDGS. Grass type was the major contributor in determining the fatty acid profile, especially in the neutral lipid layer. Warm-season grasses decreased concentrations of most fatty acids compared to cool-season grasses. The provision of WDGS as an energy supplement while grazing dissipated any differences caused by grass type.

Tripsacum, on the other hand, is generally regarded as being much less closely related to maize. Weatherwax,13 for example, states: Except for monoecism this genus resembles some of the Andropogoneae, such as Manisuris, much more than the other Maydeae. Collins,3a in a recent paper which has just come to hand, expresses a similar opinion in different language. He states: The relationship between Tripsacum and Zea is remote and the chief reason for introducing Tripsacum into a discussion of the phylogeny of maize is that Tripsacum is the only American representative of the group of grasses to which Euchlaena and Zea belong, that is found growing outside of cultivated areas.. Tripsacum does not cross naturally with maize. Neither natural nor artificial hybrids of these genera have ever been previously recorded, with the possible exception of some false hybrids reported by Collins and Kempton.4 These writers attempted to hybridize Tripsacum with both Zea and Euchlaena. Their cross of ...

Although animals eat all year round, there is no all season plant to use as forage. Knowing that some plants are C3 (cool season, temperate) and some plants are referred to as C4 (warm season, tropical) is a basic key to having quality forage all year long. But understanding the physiology (internal chemical changes) of both can even further improve the management of
Poaceae or Gramineae are the true grasses. They are a large family of Monocot flowering plants. There are about 10,000 species and 660 genera, and they are one of most ecologically and economically important of all plant families. Rushes, and sedges fall outside this family, but they are related.. Grasslands are about 20% of the vegetation cover of the Earth. Poaceae also live in many other habitats, including wetlands, forests, and tundra.. Domestication of poaceous cereal crops such as maize (corn), wheat, millets, and rice are eaten around the world. The Poaceae are the most economically important plant family in modern times, providing forage, building materials (bamboo, thatch) and fuel (ethanol), as well as food.. ...
Phragmites australis is a cosmopolitan grass and often the dominant species in the ecosystems it inhabits. Due to high intraspecific diversity and phenotypic plasticity, P. australis has an extensive ecological amplitude and a great capacity to acclimate to adverse environmental conditions; it can therefore offer valuable insights into plant responses to global change. Here we review the ecology and ecophysiology of prominent P. australis lineages and their responses to multiple forms of global change. Key findings of our review are that: (1) P. australis lineages are well adapted to regions of their phylogeographic origin and therefore respond differently to changes in climatic conditions such as temperature or atmospheric CO2; (2) each lineage consists of populations that may occur in geographically different habitats and contain multiple genotypes; (3) the phenotypic plasticity of functional and fitness-related traits of a genotype determine the responses to global change factors; (4) genotypes with

Tall fescue is the most widely grown cool-season species in North Carolina. For a cool-season species, tall fescue is tolerant to heat and drought, disease resistant, and persists with minimum care. It has a tendency to clump due to its bunch-type growth habit and may need to be re-seeded each year in areas that exhibit thin growth patterns due to excessive summer stresses. Tall fescue is easily confused with Kentucky bluegrass, annual ryegrass, and perennial ryegrass. However, Kentucky bluegrass has a boat-shaped leaf tip and distinctive light-colored lines on both sides of the midrib. Tall fescue has rolled vernation in the leaf bud and perennial ryegrass has folded vernation. Also, tall fescue has rough leaf blade margins whereas annual and perennial ryegrass have smooth ones. Tall fescue and perennial ryegrass both have non-clasping auricles, whereas annual ryegrass has clasping auricles. The backside of the tall fescue leaf blade is less glossy than that of annual ryegrass.. ...
We report the discovery and spread of a dwarf ecotype of Spartina alterniflora in San Francisco Bay. Relative to typical S. alterniflora, this dwarf ecotype has one-fifth the tiller height (~21 cm), tenfold the tiller density (~4000 tillers/m²), and is restricted to growth in the upper intertidal zone. Chromosome counts of the dwarfs are identical to typical smooth cordgrass (2n = 62), and smooth cordgrass-specific random amplified DNA markers confirm the species identity of the dwarf. Field-collected clonal fragments of the dwarf grown for 2 yr under high-nutrient conditions maintained the dwarf syndrome, as did plants grown from the seed of a dwarf. The dwarf condition is not caused by endophytic fungi. The first dwarf smooth cordgrass patch was discovered in 1991, and by 1996 five separate dwarf patches had appeared within 200 m of the original. Since 1991, total area covered by the dwarf ecotype has increased sixfold to 140 m². The ecological range of the dwarf smooth cordgrass ecotype is ...

The cool-season grasses (ryegrass, rye, wheat, oats, triticale, and fescue) provide valuable winter and spring grazing when the warm-season perennial grasses are not growing. Cool-season grasses are high-quality forages and can be the main source of feed for the cow herd, or they can be used as a protein and energy supplement through the practice of limit grazing. The most efficient use of these grasses may be for younger animals that need a higher-quality forage than required by mature animals. Although cool-season grasses are expensive to plant and grow, in areas of the state where they can be grown successfully, they can be a less costly substitute for energy and protein supplements purchased off the ranch. Soil moisture (rainfall) is the key to successfully growing cool-season grasses in Florida.. Cool-season forages require soils that are above average in soil moisture-holding capacity. They can be grown on the heavier sandy loam and clay soils of north and northwest Florida, as well as ...
Orchardgrass and tall fescue seed crops are commonly springplanted in Oregon, but do not produce a marketable crop during the first growing season. Establishing orchardgrass and tall fescue with cereal companion crops would provide income during the seeding year and could increase seed production profits. This study was conducted to evaluate the feasibility of establishing orchardgrass and tall fescue seed crops with spring wheat, barley, and oats, and to examine the morphological, physiological, seed yield, and economic responses to competition with cereals. Hallmark orchardgrass and Bonanza tall fescue were interplanted with Waverly wheat, Steptoe barley, and Cayuse oats in 15- and 30-cm rows at right angles to grass rows in March 1985 and 1986 near Corvallis, OR. Spring cereals reduced the photosynthetic photon flux density (PPFD) available for grass seedling growth, causing transient increases in chlorophyll content and lower soil temperatures. Soil water content was also depleted, ...

ABSTRACT: Genetic diversity is the fundamental level of biological diversity. In the discussion of biological diversity in agricultural ecosystems, this level is of major importance, but often neglected. Tools for the direct measurement of genetic diversity, especially in highly diverse systems such as permanent grassland, are demanding and the relationship between genetic diversity and management practices or environmental factors is poorly understood. Genetic diversity of the common grassland species Dactylis glomerata was assessed using genetic diversity indices based on 29 SSR markers. Phenotypic diversity within and among selected populations was evaluated in a replicated field experiment based on ten phenotypic plant characters of agronomic relevance. Twenty populations of D. glomerata from permanent grassland from the Swiss Alps were included in the analysis. We investigated correlations between genetic diversity (genotypic/phenotypic) and farming system (conventional/organic), management

Orchard grass (Dactylis glomerata) is a common perennial grass that is frequently found in woodland edges, rough grassland, meadows and permanent pastures. In the UK and continental Europe, orchard grass, together with other native species, including fescues, occupies around 30% of pastoral land. Polyphenol oxidases are enzymes that cause enzymatic browning by conversion of natural phenolic compounds, such as monophenols to o-dihydroxyaryl compounds and subsequent oxidation to o-quinones [1]. These highly electrophilic species bind rapidly to nucleophilic sites on other compounds (e.g. phenols, amino-acids and proteins) and condense with phenols to form brown-, black- or red-colored polymers, associated with the undesired discoloration of fruit and vegetables. Recently, high levels of PPO activity have been reported in orchard grass [2]; however, to date, no endogenous substrates have been identified. In the present study, we report the isolation and structural elucidation of PPO substrates in ...
Restoration of tallgrass prairie on former agricultural land is often impeded by failure to establish a diverse native species assemblage and by difficulties with nonprairie, exotic species. High levels of available soil nitrogen (N) on such sites may favor fast-growing exotics at the expense of more slowly growing prairie species characteristic of low-N soils. We tested whether reducing N availability through soil carbon (C) amendments could be a useful tool in facilitating successful tallgrass prairie restoration. We added 6 kg/m2 hardwood sawdust to experimental plots on an abandoned agricultural field in the Sandusky Plains of central Ohio, United States, increasing soil C by 67% in the upper 15 cm. This C amendment caused a 94% reduction in annual net N mineralization and a 27% increase in soil moisture but had no effect on total N or pH. Overall, plant mass after one growing season was reduced by 64% on amended compared with unamended soil, but this effect was less for prairie forbs ...
There are two informal groups of grasses: cool season grasses and warm season grasses. Cool season grasses flower and go to seed in the spring and early summer. Warm season grasses flower and fruit in the late summer and fall. Cool-season grasses grow rapidly during spring and early summer when days are warm and nights are cool. When temperatures rise much above 90°, they stop growing or even go dormant. They begin to grow again in the fall when daytime temperatures drop and stop growing only when it gets too cold. Some cool season species may even remain green during Georgias mildest winters. Although warm-season grasses are the backbone of prairies, cool-season grasses play an important role in sustaining wildlife early in the growing season. On the other hand, warm-season grasses flourish in Georgias hot summers and dry autumns. They have adapted to such conditions by evolving a special kind of photosynthesis called C4 that reduces the amount of moisture lost during photosynthesis, ...

The pistillate flowers are depressed into the sculptured rachis of the raceme and are quite striking to look at. Gamma Grass is an important prairie grass in the midwestern U.S ...
The pyrolytic kinetics of |i|Phragmites australis|/i| was investigated using thermogravimetric analysis (TGA) method with linear temperature programming process under an inert atmosphere. Kinetic expressions for the degradation rate in devolatilization and combustion steps have been obtained for |i|P. australis|/i| with Dollimore method. The values of apparent activation energy, the most probable mechanism functions, and the corresponding preexponential factor were determined. The results show that the model agrees well with the experimental data and provide useful information for the design of pyrolytic processing system using |i|P. australis|/i| as feedstock to produce biofuel.
Genetic drift of germplasm in cultivated wheat is good motivation for studying genetic diversity in its wild relatives. In this study, R-RAP, a new retrotransposon-based marker, was applied to assess the structure and genetic diversity of 30 accessions of Aegilops sp. originating from different geographical regions of Iran. The 15 R-RAP primer combinations revealed a total of 338 bands ranging from 16 (LTR1061 - OPA02) to 29 (LTR2116 - OPG06), with an average of 22.5 bands per primer. The size of the amplified bands varied from 100 to 1500bp. The total average of polymorphism information content (PIC) was 0.30. The highest PIC value (0.46) was for primer LTR1061-OPG06. Of the three studied Aegilops species, Ae. tauschii possesses the highest level of genetic diversity. UPGMA cluster separated the three Aegilops species into three discrete groups. Results show that R-RAP markers could be a reliable marker system for organizing genetic variability and detecting useful diversity for wheat breeding purposes

It took awhile before I became okay with the idea of drinking wheatgrass juice. In realizing the benefits of wheatgrass it was something I didnt want to miss out on. Wheatgrass shots at your local health food store can be very pricey. So, last spring we started to grow our own wheatgrass for its health benefits.. Currently, I take wheatgrass shots about once a week to boost the Vitamin K in my system (did this w first pregnancy, too). This way we can opt out of our son receiving the Vitamin K shot after birth -unless there are visible signs of bruising. Be sure to consult your midwife or physician if your are pregnant or nursing before consuming wheatgrass. In any case, we set up a seed starter tray with soil and planted wheatgrass.. Growing wheatgrass, otherwise known as, Liquid Sunshine is very easy to do. Wheatgrass grows quickly. It only takes 3-5 days to emerge in soil 1/8 of inch deep. You can grow it all year round but the preferred temps for wheatgrass to grow is between 50-80 ...

About 25% of European livestock intake is based on permanent and sown grasslands. To fulfill rising demand for animal products, an intensification of livestock production may lead to an increased consumption of crop and compound feeds. In order to preserve an economically and environmentally sustainable agriculture, a more forage based livestock alimentation may be an advantage. However, besides management, grassland productivity is highly vulnerable to climate (i.e., temperature, precipitation, CO2 concentration), and spatial information about European grassland productivity in response to climate change is scarce. The process-based vegetation model ORCHIDEE-GM, containing an explicit representation of grassland management (i.e., herbage mowing and grazing), is used here to estimate changes in potential productivity and potential grass-fed ruminant livestock density across European grasslands over the period 19612010. Here potential grass-fed ruminant livestock density denotes the maximum ...
The spread of an alien invasive grass (gamba grass-Andropogon gayanus) in the tropical savannas of Northern Australia is a major threat to habitat quality and biodiversity in the region, primarily through its influence on fire intensity. Effective control and eradication of this invader requires better insight into its spatial distribution and rate of spread to inform management actions. We used full-waveform airborne LiDAR to map areas of known A. gayanus invasion in the Batchelor region of the Northern Territory, Australia. Our stratified sampling campaign included wooded savanna areas with differing degrees of A. gayanus invasion and adjacent areas of native grass and woody tree mixtures. We used height and spatial contiguity based metrics to classify returns from A. gayanus and developed spatial representations of A. gayanus occurrence (1 m resolution) and canopy cover (10 m resolution). The cover classification proved robust against two independent field-based investigations at 500 m2 (R2 = 0.87,
An accurate assessment of forage quality is required to allow prediction of animal performance. One of the most commonly used methods of forage evaluation is to measure lignin content, with more heavily lignified materials being considered less digestible. Two measures of lignin, acid detergent lignin (ADL) and acetyl bromide lignin (ABL), were assessed with regard to their ability to predict forage digestibility. Big bluestem forage samples were collected from three ungrazed, annually burned pastures at 38, 58, and 97 days postburn. These times were selected to represent a broad range of forage quality. Cell wall material was treated chemically by: 1) partial delignification (chlorite), 2) isolation o f - cellulose, or 3) NaOH extraction. Control and treated cell-w all material was analyzed for ABL and ADL and 24 and 72 hr in vitro dry matter disappearance (IVDMD). ABL increased with advancing maturity for intact fibers, whereas ADL was highest in the most mature forage but lowest for the ...

Male Albino Wistar rats (180-220 g) were administered with streptozotocin (STZ, 50 mg/kg) intraperitoneally to induce experimental diabetes. Alkaline phosphatase (ALKP), serum glutamate oxaioacetate transaminase (SG0T), serum glutamate pyruvate transaminase (SGPT), croatinine (CRTN) and total protein (TP), urine sugar (US) and total haemoglobin (Hb) were estimated at the beginning and after 14 days of treatment. Daily oral administration of aqueous extract of Cynodon dactylon suspended in distilled water at 500 mg/kg dose almost normalized various ...
As a representative warm-season grass, Bermudagrass [Cynodon dactylon (L). Pers.] is widely used in turf systems. However, low temperature remarkably limits its growth and distribution. ABA is a crucial phytohormone that has been reported to regulate much important physiological and biochemical processes in plants under abiotic stress. Therefore, the objective of this study was to figure out the effects of ABA on the cold-sensitive (S) and cold-resistant (R) Bermudagrass genotypes response to cold stress. In this study, the plants were treated with 100 µM ABA solution and exposed to 4°C temperature. After 7 days of cold treatment, the electrolyte leakage (EL), malonaldehyde (MDA) and H2O2 content were significantly increased in both genotypes compared with control condition, and these values were higher in R genotype than those of S genotype, respectively. By contrast, exogenous ABA application decreased the electrolyte leakage (EL), malonaldehyde (MDA) and H2O2 content in both genotypes compared with
Perennial ryegrass is a cool-season, bunch-type grass. Improved turf-type perennial ryegrasses are finer textured, denser, more persistent and have better mowing quality than the forage types. They are well adapted to temperate climates as permanent turfgrass and are particularly suited for sports fields and golf course fairways. In subtropical climates, they are primarily used for over-seeding warm-season species. They are intolerant of climatic extremes of cold, heat, and drought. Perennial ryegrass grows best in neutral to slightly acid, moist soils of moderate to high fertility. It is used as a nurse grass in cool-season turfgrass seed and an ideal component for cool-season mixtures with Kentucky bluegrass and fine fescues.

of the three grass treatments were sown in spring 1989. Endophyte incidence (% infected tillers) was 40% in +E ryegrass and 0% in -E ryegrass. Tillers were vegetative. Ewe hoggets (15) were introduced into the plots and their preferences recorded by visual observations from a raised viewing tower, and agronomic measurements on the plots. On day 1 of grazing a high proportion (76%) of ewe hoggets grazed tall fescue while a low proportion (12%) grazed both +E and -E ryegrass. From day 2 to 10 of grazing a similar number of sheep grazed each grass treatment. Grass leaf height declined less in +E ryegrass (48%), than -E ryegrass (64%) and tall fescue (71%) during grazing. Pseudostem height of grasses was reduced 4.2mm in tall fescue and -E ryegrass but only 1.5mm in +E ryegrass by grazing. Pasture mass declined more in -E ryegrass (1230 kg DM/ha) than +E ryegrass (1100 kg DM/ha) or tall fescue (1020 kg DM/ha). The percentage green grass cover (point analysis first hits) decreased with grazing in all ...
MADS-box genes are categorized into A, B, C, D and E classes and are involved in floral organ identity and flowering. Sheepgrass (Leymus chinensis (Trin.) Tzvel) is an important perennial forage grass and adapts well to many adverse environments. However, there are few studies on the molecular mechanisms of flower development in sheepgrass, especially studies on MADS-domain proteins. In this study, we cloned 11 MADS-box genes from sheepgrass (Leymus chinensis (Trin.) Tzvel), and phylogenetic analysis of the 11 genes with their homologs revealed that they are divided into nine subclades. Tissue-specific expression profile analysis showed that most of these MADS-box genes were highly expressed in floral organs. LcMADS1 and LcMADS3 showed higher expression in the stamen than in the other tissues, and LcMADS7 showed high expression in the stamen, glume, lemma and palea, while expression of LcMADS2, LcMADS9 and LcMADS11 was higher in vegetative organs than floral organs. Furthermore, yeast two-hybrid

The classification of grass pollen is a classic problem in palynology. One approach to this problem is to image grass pollen using scanning electron microscopy (SEM) and to construct morphotypes on the basis of surface ornamentation patterns. In this paper, we construct a database of published SEM images of grass pollen surface ornamentation and use this database to review the status and utility of grass pollen morphotypes. Very little SEM data on grass pollen surface ornamentation have been collected. There are more SEM data on the pollen of species from larger subfamilies such as the Pooideae, but there are no SEM data on the pollen of relatively small subfamilies or the early-diverging APP clade of grasses. The available data support the following six morphotypes: the Hordeum-type, Triticum-type, Avena-type, Setaria-type, Pariana-type and Stipa-type. The phylogenetic distribution of these morphotypes cannot be assessed reliably with the available data, but the Pariana and Stipa types are ...
Poaceae or Gramineae are the true grasses. They are a large family of Monocot flowering plants. There are about 10,000 species and 660 genera, and they are one of most ecologically and economically important of all plant families.[1] Rushes, and sedges fall outside this family, but they are related. Grasslands are about 20% of the vegetation cover of the Earth. Poaceae also live in many other habitats, including wetlands, forests, and tundra. Domestication of poaceous cereal crops such as maize (corn), wheat, millets, and rice are eaten around the world. The Poaceae are the most economically important plant family in modern times, providing forage, building materials (bamboo, thatch) and fuel (ethanol), as well as food. ...
Tall fescue ( Festuca arundinaceaSchreb.) is a major cool season forage and turf grass in the temperate regions of the world. It is also a close relative of other important forage and turf grasses,...
Tall fescue was introduced into the United States in the late 19th century, but it did not establish itself as a widely used perennial forage until the 1940s. As in Europe, tall fescue has become an important, well-adapted cool season forage grass for agriculture in the US with many cultivars. In addition to forage, it has become an important grass for turf and soil conservation. Tall fescue is the most heat tolerant of the major cool season grasses. Tall fescue has a deep root system compared to other cool season grasses. This non-native grass is well adapted to the transition zone Mid Atlantic and Southeastern United States and now occupies over 35,000,000 acres (140,000 km2).[4] Tall fescue has become an invasive species and noxious weed in native California grasslands and habitats, such as the California coastal prairie plant community. The dominant cultivar grown in the United States is Kentucky 31. In 1931 E. N. Fergus, a professor of agronomy at the University of Kentucky, collected ...
With the availability of rice and sorghum genome sequences and ongoing efforts to sequence genomes of other cereal and energy crops, the grass family (Poaceae) has become a model system for comparative genomics and for better understanding gene and genome evolution that underlies phenotypic and ecological divergence of plants. While the genomic resources have accumulated rapidly for almost all major lineages of grasses, bamboo remains the only large subfamily of Poaceae with little genomic information available in databases, which seriously hampers our ability to take a full advantage of the wealth of grass genomic data for effective comparative studies. Here we report the cloning and sequencing of 10,608 putative full length cDNAs (FL-cDNAs) primarily from Moso bamboo, Phyllostachys heterocycla cv. pubescens, a large woody bamboo with the highest ecological and economic values of all bamboos. This represents the third largest FL-cDNA collection to date of all plant species, and provides the first
The main objectives of this research were to determine socioeconomic characteristics and communication behavior of small holder cattle owners, to determine what practices are being applied by the farmers in the present farming system, to determine problems encountered by farmers, and to determine the awareness level of grass silage in the region and possible contributions that grass silage will make to the farmers in the region. It is aimed also to develop recommendations for the region to accelerate the adoption and diffusion process of this technology. Descriptive statistics were used for data analyses. Research findings showed that small holder cattle farmers are mostly older people and operate in conventional ways. They face serious problems with drying their grass and lack information about grass silage. In order to adopt grass silage, farmers must be aware of its benefits, and extension work is needed for this purpose.. Keywords: grass silage, diffusion of innovations, adoption of ...

Phyllostachys nigra, or Black Bamboo, is a giant grass characterized by large woody stems that is native to Southern China. Plants spread by very vigorous rhizomes and it is considered a running form of bamboo. In nature, plants will reach 25 feet (>7.6 m) tall and the stem at maturity will reach 2 inches (5 cm) in diameter. Clumps can become very large if left uncontrolled. The stems start out green and become speckled, changing to brownish or purplish black at maturity. Leaves are medium green, 6 inches (15 cm) long and about 1/2 to 1 inch (1.25-2.5 cm) wide. In containers, it make an outstanding looking plant, but due to the vigorous growth they will outgrow most containers in a couple of years. I have seen this plant break ceramic pots with their rhizomes. In the landscape, they make great hedge plant, but be careful about controlling their roots. It is hardy in the landscape in USDA zones 8-10. Blooming: In the greenhouse, our plants have never bloomed. This could be due to our controlling ...

Cool-season forage grasses have evolved, and continue to evolve, in natural ecosystems subject to environmental factors both in the presence and absence of human influences. The literature often lacks facts describing the evolution and domestication of forage grasses. Furthermore, the literature on this subject mainly deals with evolution of species in the broad scope, i.e., on a scale of hundreds of thousands or millions or years. Thus, some of our conclusions are necessarily speculative and are highly subject to the nature of the research that has been reported. We describe the forces of selection that act upon cool-season forage grasses and attempt to place each in historical perspective and in relation to each other. Because most economically important cool-season forage grasses are perennial, our principal focus will be on perennial species. There has been very little effort to quantify economic values of selection criteria or to empirically compare different breeding procedures in cool-season
