Using empirical data to model transgene dispersal. (1/26)

One element of the current public debate about genetically modified crops is that gene flow from transgenic cultivars into surrounding weed populations will lead to more problematic weeds, particularly for traits such as herbicide resistance. Evolutionary biologists can inform this debate by providing accurate estimates of gene flow potential and subsequent ecological performance of resulting hybrids. We develop a model for gene flow incorporating exponential distance and directional effects to be applied to windpollinated species. This model is applied to previously published data on gene flow in experimental plots of Agrostis stolonifera L. (creeping bentgrass), which assessed gene flow from transgenic plants resistant to the herbicide glufosinate to surrounding non-transgenic plants. Our results show that although pollen dispersal can be limited in some sites, it may be extensive in others, depending on local conditions such as exposure to wind. Thus, hybridization under field conditions is likely to occur. Given the nature of the herbicide resistance trait, we regard this trait as unlikely to persist in the absence of herbicide, and suggest that the ecological consequences of such gene flow are likely to be minimal.  (+info)

Heat sensitivity in a bentgrass variant. Failure to accumulate a chloroplast heat shock protein isoform implicated in heat tolerance. (2/26)

Two variants of creeping bentgrass (Agrostis stolonifera cv palustris), developed using tissue culture, have been used to determine the roles of chloroplast-localized small heat shock proteins (CP-sHSPs) in heat tolerance. Results from previous research indicate that the heat-tolerant variant expressed two additional CP-sHSP isoforms not expressed in the heat-sensitive variant, that accumulation of the additional CP-sHSP isoforms was genetically linked to thermotolerance, and that the presence of the additional isoforms in the heat-tolerant variant provided greater protection to photosystem II during heat stress. To determine the basis of the differential expression, we isolated the genes encoding the CP-sHSPs from both variants and characterized their structure and expression. Two genes, ApHsp26.2 and ApHsp26.7a, were isolated from the heat-tolerant variant, and three genes, ApHsp26.2m, ApHsp26.8, and ApHsp26.7b, were isolated from the heat-sensitive variant. The sequence of ApHsp26.2m from the heat-sensitive variant was identical to ApHsp26.2, except for a point mutation that generated a premature stop codon. Therefore, the protein product of ApHsp26.2m did not accumulate in the heat-sensitive line. Mass spectrometry analysis confirmed that ApHsp26.2 encoded for the CP-sHSP isoforms unique to the heat-tolerant variant. An identical mutation was detected in one of the three parental lines used to develop the creeping bentgrass variants. This suggests that ApHsp26.2m was inherited from this parent and did not arise from a mutation that occurred during tissue culture. The presence of two isoforms encoded by the same gene might be due to differential processing of the N-terminal amino acids during or after import into the chloroplast.  (+info)

Evidence for landscape-level, pollen-mediated gene flow from genetically modified creeping bentgrass with CP4 EPSPS as a marker. (3/26)

Sampling methods and results of a gene flow study are described that will be of interest to plant scientists, evolutionary biologists, ecologists, and stakeholders assessing the environmental safety of transgenic crops. This study documents gene flow on a landscape level from creeping bentgrass (Agrostis stolonifera L.), one of the first wind-pollinated, perennial, and highly outcrossing transgenic crops being developed for commercial use. Most of the gene flow occurred within 2 km in the direction of prevailing winds. The maximal gene flow distances observed were 21 km and 14 km in sentinel and resident plants, respectively, that were located in primarily nonagronomic habitats. The selectable marker used in these studies was the CP4 EPSPS gene derived from Agrobacterium spp. strain CP4 that encodes 5-enol-pyruvylshikimate-3-phosphate synthase and confers resistance to glyphosate herbicide. Evidence for gene flow to 75 of 138 sentinel plants of A. stolonifera and to 29 of 69 resident Agrostis plants was based on seedling progeny survival after spraying with glyphosate in greenhouse assays and positive TraitChek, PCR, and sequencing results. Additional studies are needed to determine whether introgression will occur and whether it will affect the ecological fitness of progeny or the structure of plant communities in which transgenic progeny may become established.  (+info)

Comparison of early development of three grasses: Lolium perenne, Agrostis stolonifera and Poa pratensis. (4/26)

BACKGROUND AND AIMS: To improve the management of grass communities, early plant development was compared in three species with contrasting growth forms, a caespitose (Lolium perenne), a rhizomatous (Poa pratensis) and a caespitose-stoloniferous species (Agrostis stolonifera). METHODS: Isolated seedlings were grown in a glasshouse without trophic constraints for 37 d (761 degrees Cd). The appearance of leaves and their location on tillers were recorded. Leaf appearance rate (LAR) on the tillers and site-filling were calculated. Tillering was modelled based on the assumption that tiller number increases with the number of leaves produced on the seedling main stem. Above- and below-ground parts were harvested to compare biomass. KEY RESULTS: Lolium perenne and A. stolonifera expressed similar bunch-type developments. However, root biomass was approx. 30 % lower in A. stolonifera than in L. perenne. Poa pratensis was rhizomatous. Nevertheless, the ratio of above-ground : below-ground biomass of P. pratensis was similar to that of L. perenne. LAR was approximately equal to 0.30 leaf d(-1) in L. perenne, and on the main stem and first primary tillers of A. stolonifera. LAR on the other tillers of A. stolonifera was 30 % higher than on L. perenne. For P. pratensis, LAR was 30 % lower than on L. perenne, but the interval between the appearance of two successive shoots from rhizomes was 30 % higher than the interval between two successive leaf stages on the main stem. Above-ground parts of P. pratensis first grew slower than in the other species to the benefit of the rhizomes, whose development enhanced tiller production. CONCLUSIONS: Lolium perenne had the fastest tiller production at the earliest stages of seedling development. Agrostis stolonifera and P. pratensis compensated almost completely for the delay due to higher LAR on tillers or ramets compared with L. perenne. This study provides a basis for modelling plant development.  (+info)

Identification of a gene in the process of being lost from the genus Agrostis. (5/26)

Lineage-specific gene loss is considered one of the processes contributing to speciation and genome diversity. Such gene loss has been inferred from interspecies comparisons of orthologous DNA segments. Examples of intraspecific gene loss are rare. Here we report identification of a gene, designated Crs-1 (creeping specific-1), that appears to be in the process of being lost from heterozygous populations of the species creeping bentgrass (Agrostis stolonifera). The Crs-1 gene encodes a protein with an N-terminal dirigent protein domain and a C-terminal lectin domain and is similar to the maize (Zea mays) beta-glucosidase aggregating factor. Most individual creeping bentgrass plants examined are lacking Crs-1. Some individuals are hemizygous for the Crs-1 locus, indicating major haplotype noncolinearity at that locus. Crs-1 was not detected in several other Agrostis species, indicating it is being lost from the genus. The Crs-1 locus in creeping bentgrass provides a rare example of the evolutionary process of gene loss occurring within a plant species.  (+info)

Root respiratory characteristics associated with plant adaptation to high soil temperature for geothermal and turf-type Agrostis species. (6/26)

Respiration is a major avenue of carbohydrates loss. The objective of the present study was to examine root respiratory characteristics associated with root tolerance to high soil temperature for two Agrostis species: thermal Agrostis scabra, a species adapted to high-temperature soils in geothermal areas in Yellowstone National Park, and two cultivars ('L-93' and 'Penncross') of a cool-season turfgrass species, A. stolonifera (creeping bentgrass), that differ in their heat sensitivity. Roots of thermal A. scabra and both creeping bentgrass cultivars were exposed to high (37 degrees C) or low soil temperature (20 degrees C). Total root respiration rate and specific respiratory costs for maintenance and ion uptake increased with increasing soil temperatures in both species. The increases in root respiratory rate and costs for maintenance and ion uptake were less pronounced for A. scabra than for both creeping bentgrass cultivars (e.g. respiration rate increased by 50% for A. scabra upon exposure to high temperature for 28 d, as compared with 99% and 107% in 'L-93' and 'Penncross', respectively). Roots of A. scabra exhibited higher tolerance to high soil temperature than creeping bentgrass, as manifested by smaller decreases in relative growth rate, cell membrane stability, maximum root length, and nitrate uptake under high soil temperature. The results suggest that acclimation of respiratory carbon metabolism plays an important role in root survival of Agrostis species under high soil temperatures, particularly for the thermal grass adaptation to chronically high soil temperatures. The ability of roots to tolerate high soil temperatures could be related to the capacity to control respiratory rates and increase respiratory efficiency by lowering maintenance and ion uptake costs.  (+info)

Lifetime reproductive success and density-dependent, multi-variable resource selection. (7/26)

Individuals are predicted to maximize lifetime reproductive success (LRS) through selective use of resources; however, a wide range of ecological and social processes may prevent individuals from always using the highest-quality resources available. Resource selection functions (RSFs) estimate the relative amount of time an individual spends using a resource as a function of the proportional availability of that resource. We quantified the association between LRS and coefficients of individual-based RSFs describing lifetime resource selection for 267 female red deer (Cervus elaphus) of the Isle of Rum, Scotland, from 1970 to 2001. LRS was significantly related to first- and second-order effects of selection for Agrostis/Festuca grassland and proximity to the sea coast (quality of forage within Agrostis/Festuca grassland was highest nearest the coast (ratio of short:long grassland)). The benefits of selecting for quality in Agrostis/Festuca grassland, however, traded-off with increases in LRS gained by avoiding conspecific density. LRS was inversely associated with local density, which was highest along the coast, and reproductive benefits of selecting Agrostis/Festuca grassland diminished with increasing density. We discuss the relevance of these results to our understanding of the spatial distribution of red deer abundance, and potential applications of our approach to evolutionary and applied ecology.  (+info)

Many floras and guides to grasses say that this is a plant of dry places but this was growing with its feet in water in a small trackside ditch. Other field botanists have noted that this is a plant which doesnt read the guides and chooses to grow in the wrong places. Like all Agrostis species there is variability and the florets are tiny so from a distance the panicles have a brown misty appearance. In this case there are usually awns which were present on the plants at this site - but to make identification difficult the awns do fall off as the flower spike ripens. It also should have rhizomes which again we found on these plants rather than stolons on the quite similar Agrostis canina (Velvet Bent). They were also a lot taller than the book height. The one I brought home was of average height in the community from which it was taken where there were hundreds. It was 132 cm tall - but should be up to 60 cm according to Stace..

Interpretive Summary: Dead Spot is a new disease of grasses that is spreading rapidly. Since its discovery in 1998 in Maryland, it has been found in 11 states. The disease is caused by a newly described species in the fungal genus Ophiosphaerella. Species in this genus belong to a very important class of fungi, many of which are serious agricultural pests that attack many crops. Little is known about the biology or genetics of these fungi, and O. agrostis in particular. O. agrostis is unusual in that it produces prodigious numbers of sexual fruiting bodies in the field throughout the summer months and has no other known spore stage. Production of fruiting bodies increases the chance for genetic recombination which provides the fungus with the capability to adapt and increase its fitness as a pathogen. ...

Traffic is a significant force at play on turfgrasses, especially on sports fields and golf courses. Previous studies have characterized the effect of traffic in the morning at 0700 HR and 0900 HR on golf course greens when the turfgrass canopy temperature is below freezing (0◦C) (Baldwin et al., 2008). This study was performed to determine the effect, if any, of traffic at 0800 HR on a Crenshaw creeping bentgrass (Agrostis stolonifera L.) putting green when the turfgrass canopy temperature was below freezing. The study was also initiated to determine if afternoon traffic at 0300 HR on the same day as the morning traffic had an impact on the turfgrass playability, performance, and health. In addition, potassium (K) is a required plant nutrient that is often applied to turfgrasses, especially creeping bentgrass, in order to help the plant tolerate stresses. It has been suggested that fall K fertilization can aid in creeping bentgrass winter traffic tolerance, but research on the subject is limited
Summer bentgrass decline is associated with inhibition of plant growth and cytokinin production. This study was designed to investigate whether shoot and root growth and cytokinin production for creeping bentgrass (Agrostis stolonifera L.) exposed to heat stress would be improved by extending photoperiod. Penncross plants were initially grown in growth chambers at 20/15°C (day/night) and at a 14-h photoperiod for 60 d, and then exposed to 33/28°C (heat stress) with three different photoperiods: 14 (control), 18, and 22 h (extended photoperiod) daily for 32 d. Root number, fresh weight, viability, turf quality, and shoot extension rate declined during heat stress at the 14-h photoperiod. The decline was delayed and suppressed by extending photoperiod from 14 to 18 or 22 h. Root growth, turf quality, and shoot extension rate increased with extending photoperiod. Cytokinin content in roots and leaves also decreased during heat stress at the 14-h photoperiod. Plants at the 22- and 18-h ...

High temperature is a major factor limiting growth of creeping bentgrass (Agrostis palustris Huds.). Physiological causes of turf growth and quality decline with increasing temperature is not well understood. The objective of the study was to examine responses of growth and carbohydrate metabolisms to increasing temperatures in three creeping bentgrass cultivars. Sods of `Penncross, `ISI-AP-89150, and `SR 1020 were grown in growth chambers and exposed sequentially for 20 d to each of the following temperatures: 20, 24, 30, 34, and 38°C. Evaluation and measurements were made at 10 and 20 d after each sequential temperature increase. Decreased root viability and root dry matter production of all cultivars was observed after a 10-d exposure at 30°C and continued to decline with increasing temperatures. A decline in turf quality and leaf chlorophyll content (Chl) was observed at a 20-d exposure to 30°C. Turf quality, Chl content, and root viability of SR 1020 were higher than those of ...
Summary Although many native species are now used in the revegetation of soil disturbances in Australian alpine areas, exotic species were, until recently, the only components of seed mixes. The use of exotic species and fertilizer was justified by their availability and low cost, and the prediction that native species would replace the exotic sward, presumably once soil nutrient levels dropped to those found in native vegetation. There was no apparent regard for the invasive capacities of the exotic species used. An investigation of a road verge on the Bogong High Plains, revegetated with a mixture of exotic species in the late 1950s, has shown that colonization by native plants can be very slow. Although many native species had colonized by 1993, exotic species still provided 50% of the cover. Agrostis capillaris accounted for most of this. The major native colonizers were Carex spp., Colobanthus affinis, Euchiton spp., Leptinella filicula, Poa hiemata, Ranunculus victoriensis and Scleranthus ...
Creeping bentgrass (Agrostis palustris) is the predominant turfgrass used on putting greens, providing a uniform, high-quality putting surface. However, the demand for faster green speeds and higher-quality, more stress-tolerant turf has led to the development of many new cultivars.Superintendents interested in converting their greens to one of these new cultivars face a dilemma.

So who could have possibly initially discovered this saprophytic, nearly subterranean and leafless plant growing amongst the club moss Selaginella and the ground-hugging mosses Aneura and Hypnum beneath wet prairie species such as Sweetflag (Acorus americanus), Redtop (Agrostis gigantea), Swamp Milkweed (Asclepias incarnata), Common Boneset (Eupatorium perfoliatum), Grass-leaved Goldenrod (Euthamia sp.), Blueflag Iris (Iris virginica), Black-eyed Susan (Rudbeckia hirta), and Late Goldenrod (Solidago gigantea) in a remnant lake plain prairie of glacial Lake Chicago? It was none other than the sharp-eyed 23-year old University of Chicago botany graduate student Norma Etta Pfeiffer, who was on all fours searching for liverworts on that memorable August morning. As a result of her amazing discovery and subsequent research on the new-to-science plant she named Thismia americana, Pfeiffer just two years later became the youngest person to receive a PhD from the University of Chicago.

The results of the physiological traits evaluated in this study indicate that both PsgSLTZ and Penncross creeping bentgrass experienced similar levels of damage due to salt treatments in both experiments. Salt exposure of these two creeping bentgrass cultivars resulted in an accumulation of Na+ in plant leaves and a reduction in Ca2+ and K+ content in both experiments. PsgSLTZ exhibited significantly higher K+ (throughout salt treatment), significantly lower Na+ (on the last day of salt stress in both experiments), less change in Ψs (on most dates of both experiments) compared with Penncross. This is relatively consistent with our previous studies of other creeping bentgrass cultivars differing in salt tolerance (Krishnan and Merewitz, 2015). Salt stress may reduce the content of K+ and Ca2+ and maintenance of K+ is associated with salt tolerance (Krishnan and Merewitz, 2015; Qian and Fu, 2005; Sairam et al., 2002). We cannot fully conclude whether the cultivars differed in salt ...
Weed control in bentgrass is not impossible, but choices are limited and effective management can be difficult.While herbicide technology has led to the development of numerous products that control obscure weeds, why are so few of these products registered for use on bentgrass and bentgrass greens?

Growth chamber studies were conducted with the objectives of evaluating variations in heat tolerance for a mapping population of creeping bentgrass segregating for disease resistance and identifying QTL markers associated with heat tolerance utilizing the available linkage maps. The ultimate goal is to dissect the complex inheritance of quantitative traits associated with drought and heat tolerance and to identify QTL markers, which could potentially be used in molecular marker- assisted selection for improving drought and heat tolerance in creeping bentgrass. First year data has been collected and is being analyzed. Plants from an experimental creeping bentgrass mapping population were established and inoculated with Sclerotinia homoeocarpa at the University of Maryland Turfgrass Research Center, College Park, MD. Extensive disease development has been observed and initial ratings show significant disease resistance differences exist between members of the population. Data analysis indicates ...
Gray leaf spot often develops first in heat or drought prone areas such as the tops of small mounds or on steep slopes. The diseased turf first appears droughty even though soil moisture is sufficient but soon collapses and turns a dull brown (Figure 1). The fungus may quickly spread from these diseased patches and cause extensive blighting if weather conditions are favorable for infection (Figure 2). In some years the disease never progresses beyond blighting in these hot spots. Other turfgrass species that may be mixed in with the ryegrass, including Kentucky bluegrass, annual bluegrass and creeping bentgrass, are not affected by the disease. Blighting can continue through late summer and into early fall and cause significant damage to young ryegrass seedlings emerging from fall overseeding.. Small, chocolate-brown spots about 1/16 inch in diameter develop on leaves (Figure 3). During early disease development, these leaf spots may not be numerous and can be easily overlooked. Depending on ...

There are many unanswered questions about the life history of woolly apple aphids. It was believed they overwinter only on elm trees as immature nymphs or eggs, with mature winged adults moving into orchards during the spring and summer. Recently, it was determined they can complete their lifecycle on apple, overwintering aerially or on roots. The aphids on elm are now considered to be a separate species called E. herioti (Börner) that can also develop on apple. The primary host of woolly apple aphid is unknown. Crawlers can move to roots any time they are active, mainly in June and July, and in the fall. There are winged aphids, and crawlers, and both move from tree to tree. Close tree spacing, and clean, smooth soil surfaces favour crawler migration. High soil temperatures, weed cover and distant tree spacing inhibit aphid movement between trees.. Research shows the frequency of infestation in orchards is correlated with orchard age. Orchards 25 years or older may have 70% to 100% tree ...
Abstract: The use of synthetic materials for mulching is a very common practice for vegetable crops. Soil mulching influences the microclimate around plants and soil environmental conditions. Mulching with black materials is particularly recommended for thermophilic species, especially those requiring high soil temperature. An experimet was established to evaluate an effect of soil mulching with synthetic materials (black polyethylene film, black polypropylene nonwoven 50 g∙m, black fabric 94 g∙m-2) on the fruit quality and nutritive value of two melon cultivars (Seledyn, Yupi) cultivated in the field under the climatic conditions of central-eastern Poland. The greatest numbers of fruit per 1 m2 and marketable fruit were harvested in the year 2007 which was most favourable for melon growing compared with the remaining study years. The number of the fruits which were either unripe or showed symptoms of decay did not differ significantly in individual study years. Yupi was characterised ...
The |I|Saccharomyces cerevisiae|/I| gene |I|GTS1|/I| is pleiotropic. |I|GTS1|/I| induction produces a variety of biological phenomena represented by heat tolerance. To clarify the interaction partners of Gts1p, tandem affinity purification and immunoprecipitation were performed. Ssa1p and Ssa2p, members of the 70-kDa heat-shock protein family, were identified. Co-expression of |I|SSA1|/I| or |I|SSA2|/I| inhibited Gts1p nuclear import. As compared to the wild type, the |I|SSA1|/I| and |I|SSA2|/I| double-deletion mutant showed enhancement of Gts1p-mediated heat tolerance in the stationary phase, although neither of the single deletions affected heat tolerance, irrespective of |I|GTS1|/I| induction. These results indicate that the heat tolerance function of Gts1p is regulated by Ssa1p and Ssa2p. Furthermore, time-dependent production of Ssa1p and Ssa2p revealed that Gts1p controls the production of Ssa1p and Ssa2p, and that the total amounts of Ssa1p and Ssa2p are important in inhibiting the unique
Yellow spot recently was observed in the mid-Atlantic. Yellow spot is an undescribed malady, which mainly is seen in creeping bentgrass grown in sand-based root-zones on greens and tees.

Drosera rupicola is a tuberous perennial species in the genus Drosera that is endemic to Western Australia. It produces 3 to 5 semi-erect lateral stems that grow up to 15 cm long. The turbinate tuber and mobile lamina that are capable of folding over prey distinguish it from all other members of the section Stolonifera. It is native to a large inland region from Pithara to south-east of Hyden. It grows in loamy soils near granite outcrops and flowers from July to October. It was first formally described by N. G. Marchant in 1982 as a subspecies of D. stolonifera. It was elevated to species rank by Allen Lowrie in 2005. List of Drosera species Lowrie, A. 2005.

Annual bluegrass is a winter annual grass that is problematic on golf putting greens due to its light green color, prolific seedhead production and intolerance to stress. On creeping bentgrass putting greens, herbicides for annual bluegrass control are limited. A new herbicide, methiozolin, developed by Moghu Research Center, LLC, in Daejeon, South Korea, safely and selectively controls annual bluegrass in creeping bentgrass and several other turfgrass species. Methiozolin typically controls annual bluegrass over several weeks, allowing desirable turfgrass time to grow into areas previously infested by annual bluegrass with little surface disruption. The mode of action of methiozolin is unknown, but has been proposed to act as either a cell wall biosynthesis inhibitor (CBI) or an inhibitor of tyrosine aminotransferase (TAT). Field studies were conducted at Virginia Tech to investigate strategies promoting surface recovery on putting greens following atypically rapid annual bluegrass loss ...

Several genera in the family Crambidae. Important turfgrass species affected: Creeping bentgrass, Kentucky bluegrass, Tall fescue. Damage from sod webworms is first noticed as small irregular brown patches, with grass blades chewed of at or just above the soil surface. The adult is a buff-colored moth with a 1-inch wingspan that looks tubular when at rest because of the way the wings wrap around its body. Webworm larvae are about 1 inch long and gray, with brown spots on each body segment. Larvae often hide in silk-lined, pencil-sized tubes within the thatch layer, which is a sign of their activity. Two to three generations occur during a season, and damage can be expected during the late summer when populations are peaking. Except under drought conditions, most webworm damage occurs on high-amenity turfgrasses, such as golf greens, new sod fields or newly established lawns under high fertilization. Endophyte-enhanced turfgrasses, such as tall fescue, are toxic to webworm larvae and should be ...

On the plus side... we continue to increase creeping bentgrass populations which are unaffected. There are now many areas we do not even spray. This not only improves cost effectiveness but is environmentally responsible. Areas which still contain small percentages of Annual Bluegrass are left untreated on purpose. The insect weakened Poa Annua allows the creeping bentgrass to dominate. The more desirable plant species which takes over, improves our chances at even less damage and cost in subsequent years. The trick is to balance the damage with playability to ensure member satisfaction ...

The corn cyst nematode (CCN) Heterodera zeae is a plant parasitic nematode that feeds on corn Zea mays. The CCN has a limited economic impact worldwide due to its high soil temperature requirements. CCN was first described from a population in India in 1970. It was later reported in Egypt and Pakistan. In India the CCN is considered to be one of the four economically important cyst nematodes. The first report of the species in the Western hemisphere came in 1981 from four colonies in Maryland, Harford, Cecil, Kent, and Queen Annes counties. These four counties were placed under quarantine. The nematode was later identified from Cumberland Co., VA, over 170 miles from the nearest known infested field in Maryland. In Virginia the nematode was restricted to a 3 by 2.5 mile strip of land along the Appomattox River. The cysts of CCN are light brown in color and lemon shaped. The cysts also have a zig-zag pattern on the cyst wall with four prominent finger-like bullae below the underbridge. The ...
Broccoli is becoming more popular with the American consumer, providing plenty of nutrients in the diet. But it isnt easy getting this cool-weather vegetable to your table. Broccoli producers face many factors that impede getting their crop to market-including unexpected temperature fluctuations and excessive heat. Heat stress while broccolis florets are developing can reduce crop yield and quality, cutting into the crops $800 million U.S. market value.. Broccoli has been grown in Europe for centuries, but it has only been grown in the United States since the late 1800s, when it was probably introduced by Italian immigrants. Although California is the major producing state, broccoli is grown in nearly every other state, especially along the eastern seaboard.. The likelihood of high-temperature stress occurring in a given location or season is the main factor limiting where and when the crop can be grown. Breeding heat-tolerant broccoli cultivars could extend the growing season, expand ...

If theres one thing Michelle Obama and Glenn Beck can agree on, its the notion that growing some of your own food is a good idea (though I suspect the Obamas get their seeds from sources other than Becks shifty, grifty seed bank sponsor).. You might think that level of bipartisan support would light a fire under our collective (gr)ass. But the much-ballyhooed kitchen garden revival has yet to make a dent in the bentgrass. As NASA reported in 2005, lawns now constitute "the single largest irrigated crop in America," taking up at least three times the acreage we devote to irrigated corn. Has any nation in the history of mankind ever squandered so many resources to cultivate so much vegetation of such dubious value?. Meanwhile, we currently grow less than 2 percent of our own food..

Hello Dros researchers- On the subject of growth chambers, I had the unfortunate experience with a brand-new VWR brand blowing its thermostat, having a manufacturer replacement brought in (after a few weeks negotiation) to have the replacement do the exact same thing, have yet another brought in with the same result.... Eventually they just refunded us the cost of the item and we use one of the facility cold rooms set at 18C with some fluorescent bulbs on a timer to achieve semi-optimal fly growth. 18C just isnt a temperature VWR growth chambers are happy at. Luckily, none of our mutant lines were lost to the debacle. Motto: you get what you pay for. Well eventually venture out into the world of growth chambers again (the cold room is not in an incredibly convenient place) and I will note with interest whatever information is posted on this message board on the subject.

Contemporary cooks have looked for shortcuts to the laborious process of making aioli, which may be the motivation behind one recipe that calls for heating the sauce to thicken it. This alternative recommends combining the ingredients in a food processor, then slowly heating the mixture, whisking constantly, until it thickens. When making aioli using this method, its recommended that you use heat-tolerant oil such as safflower in place of olive oil. Once again, be careful not to heat the sauce too fast, as heat will make it separate. If the sauce separates, try whisking one egg yolk in a bowl, then add the separated sauce and whisk the sauce until it emulsifies again.. ...

The latest and greatest Poa control product can yield a fortune in revenue coming back into the company that can expedite the return on investment. This was clearly the case in Colorado. In the last week I have received several phone calls from fellow Superintendents in Colorado who are experiencing the same if not worse injury to Bentgrass. To make matters worse the product Xonerate had little or no control on the Poa Annua which it is supposedly works so well on. Most of my Poa that was treated couldnt look healthier, while the amount damage that occurred to the Bentgrass makes this product unusable for me going forward. This is the exact opposite of how this product has been marketed ...
Plants adapted to cold winters go through annual cycles of gain followed by loss of freezing tolerance (cold acclimation and deacclimation). Warm spells during winter and early spring can cause deacclimation, and if temperatures drop, freezing damage may occur. Many plants are vernalized during winter, a process making them competent to flower in the following summer. In winter cereals, a coincidence in the timing of vernalization saturation, deacclimation, downregulation of cold-induced genes, and reduced ability to reacclimate, occurs under long photoperiods and is under control of the main regulator of vernalization requirement in cereals, VRN1, and/or closely linked gene(s). Thus, the probability of freezing damage after a warm spell may depend on both vernalization saturation and photoperiod. We investigated the role of vernalization and the VRN1-region on freezing tolerance of meadow fescue (Festuca pratensis Huds.), a perennial grass species. Two F2 populations, divergently selected for high and
Seashore paspalum (Paspalum vaginatum) is among the most salt- and cadmium-tolerant warm-season perennial grass species widely used as turf or forage. The objective of this study was to select stable reference genes for quantitative real-time polymerase chain reaction (qRT-PCR) analysis of seashore paspalum in response to four abiotic stresses. The stability of 12 potential reference genes was evaluated by four programs (geNorm, NormFinder, BestKeeper, and RefFinder). U2AF combined with glyceraldehyde-3-phosphate dehydrogenase (GAPDH) showed stable expression in Cd-treated leaves and cold-treated roots. U2AF and FBOX were the most stable reference genes in Cd-treated roots and cold-treated leaves. In Polyethylene Glycol (PEG)- or salt-treated roots, the reference gene U2AF paired with either ACT or CYP were stable. SAND and CACS exhibited the most stability in salt-treated leaves, and combining UPL, PP2A, and EF1a was most suitable for PEG-treated leaves. The stability of U2AF and instability of UPL and

At-a-glance: Base Temperature: 32 degrees F, Target GDD Range: 200-500, Source: Calhoun - Michigan State University (2004). As the rain falls, temperatures rise and the grass gets greener our thought turn to properly timing Proxy/Primo tankmixes on creeping bentgrass/annual bluegrass turf stands. Current thinking from MSU, based on the recent success and failures, suggests that superintendents wait for two mowings after full green-up or 200-250 growing degree-days on the GDD32 degree-day model. Results from 2003-06 showed greater success when the initial application was made earlier. We had declining results with each initial timing between 309 and 548. Best results in 2004 were with the 309 initial timing and decreasing slightly with each of the following initial timings. The results from 2005 indicated that even earlier initial timings were more effective. The second application should be made 21 days after the first. In nearly every case, two applications has performed better than one. Do not ...
Perhaps Merriam-Websters definition of cabin fever provides some insight regarding why those of us across the upper Midwest tend to be impatient and susceptible to making snap decisions about potential turf problems during that lull between final snow melt and spring green up. During this lull we look at brown, dormant golf courses each day and cannot help but wonder whether or not turf has sustained injury during the many thaw/freeze cycles that have occurred this winter.. Removing a few turf samples from greens and taking them indoors to green up is helpful, but it can be difficult to obtain a representative sample from putting surfaces that are a mottled mixture of bentgrass and Poa annua. Knowing where past winter damage has occurred on greens can increase the odds of success when sampling turf for damage. However, every spring I hear a story or two about a course where serious winterkill occurred on a green that had no history of injury in the past…so dont depend on a few healthy plugs ...
Materials And Methods. Bacterial Isolation and Identification. Seeds of eight turfgrass species were obtained from breeding program selections available at the Rutgers Research Farm in Adelphia, N.J. To remove surface bacteria, grass seeds were surface disinfected in 4 percent sodium hypochlorite solution for 30 minutes and rinsed three times with water for 30 seconds. The surface disinfected seeds were put on Potato Dextrose Agar (PDA; Difco Laboratories, Detroit, Mich.) and 10 percent Tripticase Soy Agar (TSA; Difco Laboratories, Detroit, Mich.) for isolation of bacteria.. For bacterial identification, about 1,450 base pairs of the 16S rDNA region were amplified with primers 16S-27F (5- AGAGTTTGATCMTGGCTCAG-3) and 16S-1492R (5- AAGGAGGTGWTCCARCC-3) (M=A/C, W=A/T, R=A/G). Polymerase chain reaction (PCR) amplification was conducted with the program of denaturing at 94oC for 60 seconds, annealing at 46oC for 30 seconds and extension at 72oC for 90 seconds, 36 cycles. The PCR products were ...

Susceptibility comes down to stress and in turfgrass management, stressing the sward is a daily necessity if the desired quality of the surface is to be achieved. Stress is difficult to define but involves a number of factors that can reduce the overall quality of the plant, its vigour and its ability to maintain optimal growth conditions. This is where our ability to manage close-mown fine turfgrasses is tested to the extreme because whatever we do to try and keep the plant healthy, the boundaries are constantly being changed by the environmental conditions ...

There are many perennials to grow in a shady area. Although hostas are considered primarily foliage plants due to the wide variety of colorful foliage in different shapes and sizes, they also bloom and some have a good fragrance, too. Ferns make a nice complement to hostas and add additional all season interest and variety. Astilbes are often listed as shade plants, but will need some sun during the day to bloom their best. In addition to those "big three" perennials for shade, you might consider pulmonaria, lily of the valley, bleeding heart, Japanese anemone, tricyrtis, iris cristata, lamium, epimedium, phlox stolonifera, Solomons seal, and tiarella. There are also many woodland natives such as Virginia Bluebells that will thrive in the shady garden in a soil that is humusy and evenly moist yet well drained. Have fun experimenting ...

Another issue, Crane Fly Larvae LOVE to chew on our chosen varieties and dont like the native grasses like Poa Trivialis, Poa Annua and Native Creeping Bentgrass. (see photos). Normally when our chosen varieties are growing well under normal weather conditions we can tolerate as many as 10-12 larvae per square foot. Since there is nothing "Normal" about this spring, the Crane Fly Larvae are causing more visible damage. We are always inspecting for Crane Fly Larvae. When damage is detected and an application is warranted, we will set up a Spring Curative Application for your lawn.

Very high soil test levels should be avoided as much as possible. High soil nutrient levels might not only represent an economic loss but they may also indicate potential crop, animal or environmental problems.. Very high pH can result in micronutrient deficiencies and may affect the activity of some pesticides resulting in injury or poor pest control.. Very high phosphorus levels in the soil may lead to crop production problems especially with no manure and may result in potentially harmful P loss to the environment. Best management practices may be necessary to reduce the potential for environmental problems with P.. Very high potassium levels in the soil can lead to nutrient imbalances in forage crops which can cause serious health problems in animals. Use caution when grazing forage crops, especially if the soil magnesium is not also in the high range. It may not be possible to correct these soil imbalance in the short term. Feed rations must be balanced accordingly.. ...

The mean daily temperature for the April transplanting was 16.0°C, while the mean maximum daily temperature was 24.5°C. Only 28% of all April transplants produced harvestable heads largely due to a disease rate of 45% and the fact that 12% of the plants bolted prematurely. The mean daily temperature for the June transplanting was 24.8°C. Only 20% of all June transplants produced harvestable heads due to soft rot and tipburn. In August, the mean daily temperature dropped to 21.7°C, and 66% of all plants produced harvestable heads. The mean daily temperature for the September transplanting was 15.5deg.C, and the harvestable yield was 93%. Heat-tolerant cultivars from the April and June transplanting dates could not be identified because all cultivars produced a relatively low percentage of harvestable heads. Conversely, temperatures following the September transplanting were nearly ideal for Chinese cabbage production, so heat-tolerant cultivars could not be detected. Temperatures after the ...
A total APAL nutrient analysis enables you or your agronomist to formulate and exact foliar program.. Leaf/Soil analysis: There are significant differences between a soil and plant leaf analysis. LEAF (TISSUE) ANALYSIS. Represents plant nutrient levels and uptake of elements as a result of soil levels and soil imbalances.. A leaf analysis is not always an indication of soil levels.. SOIL ANALYSIS. Shows available soil elements and mineral imbalances.. Plant uptake can be different due to soil imbalances.. UNDERSTANDING THE DIFFERENCE. BETWEEN A LEAF AND A SOIL ANALYSIS and the IMPORTANCE OF BOTH. A leaf analysis can often be seen as a reflection of the soil in that it reflects what nutrients the soils mineral balance is allowing the plant to extract eg. High soil potassium inhibit plant uptake of magnesium, high magnesium soils inhibit plant potassium, high sodium inhibits plant potassium and calcium and high soil calcium inhibits plant uptake of most trace elements, so we often see a mineral ...

Phenotypes of five transgenic lines of narrow-leafed lupin (Lupinus angustifolius [L] cv Merrit) stably transformed with the isopentenyl pyrophosphate transferase (ipt) gene from Agrobacterium tumefaciens coupled to a flower-specific promoter (TP12) from Nicotiana tabacum [L.] are described. Expression of the transgene was detected in floral tissues and in shoot apical meristems on all orders of inflorescence. In each transgenic line there was significant axillary bud outgrowth at all nodes on the main stem with pronounced branch development from the more basal nodes in three of the lines. The lowest basal branches developed in a manner similar to the upper stem axillary branches on cv Merrit and bore fruits, which, in two lines, contained a significant yield of filled seeds at maturity. Senescence of the cotyledons was delayed in all lines with green cotyledons persisting beyond anthesis in one case. IPT expression increased cytokinin (CK) levels in flowers, meristem tissues and phloem exudates ...
