Two novel species, Rathayibacter caricis sp. nov. (type strain VKM Ac-1799T = UCM Ac-618T) and Rathayibacter festucae sp. nov. (type strain VKM Ac-1390T UCM Ac-619T), are proposed for two coryneform actinomycetes found in the phyllosphere of Carex sp. and in the leaf gall induced by the plant-parasitic nematode Anguina graminis on Festuca rubra L., respectively. The strains of the novel species are typical of the genus Rathayibacter in their chemotaxonomic characteristics and fall into the Rathayibacter 16S rDNA phylogenetic cluster. They belong to two separate genomic species and differ markedly from current validly described species of Rathayibacter at the phenotypic level. The most striking feature differentiating Rathayibacter caricis sp. nov. from other species of the genus is the presence of fucose in its cell wall and Rathayibacter festucae sp. nov. can be easily recognized among other yellow-pigmented rathayibacters because of its rose-orange-coloured colonies.
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 ...
Lolitrem B is one of many toxins produced by a fungus called Epichloë festucae (var. lolii), which grows in perennial ryegrass. The fungus is symbiotic with the ryegrass; it doesnt harm the plant, and the toxins it produces kill insects that feed on ryegrass. Lolitrem B is one of these toxins, but it is also harmful to mammals. The shoots and flowers of infected ryegrass have especially high concentrations of lolitrem B, and when livestock eat too much of them, they get perennial ryegrass staggers. At low doses the animals have tremors, and at higher doses they stagger, and at higher yet doses the animals become paralyzed and die. The blood pressure of the animals also goes up. The effect of the lolitrem B comes on slowly and fades out slowly, as it is stored in fat after the ryegrass is eaten. The condition is especially common in New Zealand and Australia, and plant breeders there have been trying to develop strains of fungus that produce toxins only harmful to pests, and not to mammals. ...

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.

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, ...

Observer: Paul Lauenstein. Observation Date: 6/2/19. Observation Time: 3:15 p.m.. Observation Location: Along the dirt road under the power lines on the other side of South Main Street from Wards Berry Farm. Common Name: Deer-tongue Grass. Scientific Name: Dichanthelium clandestinum. Comments: Deer-tongue grass is a perennial cool-season grass native to eastern North America. It grows to 2′ to 4′ tall. It is tolerant of low pH soils, high concentrations of aluminum, drought conditions, and infertile soils. For these reasons, it is used in revegetating acid mine sites. Deer-tongue grass prefers moist to wet sites and does best in full sun. This grass produces two seed crops; a spring crop in an open panicle and a fall crop that remains mostly enclosed in the leaf sheath. Birds eat the seed and the plant lodges during the winter forming a dense cover for wildlife.. More Information: Roundstone Native Seed. ...

Thanks for gathering all this information into one place. Can we add some links to standards of genome annotation? In some bacteria for one example the tefA gene is annotated as a second copy of the fusA gene. The fusA encodes EF-G, the ribosomal translocase, while tefA encoded the ribosomal back-transloacase. They are quite similar in sequence, stucture and function so it is understandable that some annotators would confuse the two.. ReplyDelete ...
During the last 100 years, in Western Europe and elsewhere, considerable effort has been devoted to improving perennial ryegrass (Lolium perenne L.) for agriculture. The first persistent cultivars to be widely used were more digestible than other common pasture species but were no higher yielding than the better wild populations of perennial ryegrass. Two main approaches (here called mainstream breeding and population improvement) have been used to further improve the species for the UK, but no recent experiments to assess progress have been published. In 2006, two plot trials were established at IBERS to compare the performance of some newer cultivars and candidate varieties with the first persistent cultivars to be widely used in the UK. One trial involved comparing 10 intermediate-heading (6 diploid and 4 tetraploid) cultivars and candidate varieties with the intermediate-heading cv. Talbot, and the other involved comparing 11 late-heading (4 diploid and 7 tetraploid) cultivars and candidate ...
Spinach is a cool-season crop that can be grown in spring, fall, and even winter. Here are a few tips on growing spinach in your garden.
Lolines are specialized metabolites produced by endophytic fungi, such as Neotyphodium and Epichloë species, that are in symbiotic relationships with cool-season grasses. Lolines are vital for the survival of the grasses because their insecticidal and antifeedant properties protect the plant from insect herbivory. Although lolines have various bioactivities, they do not have any concomitant antimammalian activities. Lolines have complex structures that are unique among naturally occurring pyrrolizidine alkaloids. Lolines have four contiguous stereocenters, and they contain an ether bridge connecting C(2) and C(7) of the pyrrolizidine ring. An ether bridge connecting bridgehead C atoms is unusual in natural products and leads to interesting questions about the biosynthesis of lolines in fungal endophytes. Dr. Pan, who was a graduate student in Dr. Schardl Lab at University of Kentucky, isolated a novel metabolite, 1-exo-acetamidopyrrolizidine (AcAP). She observed that AcAP was accumulating in naturally

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 ...

Helitrons are a class of transposable elements which have been identified in a number of species of plants, animals and fungi. They are unique in their proposed rolling-circle mode of replication, have a highly variable copy-number and have been implicated in the restructuring of coding sequences both by their insertion into existing genes and by their incorporation of transcriptionally competent gene fragments. Helitron discovery depends on identifying associated DNA signature sequences and comprehensive evaluation of helitron contribution to a particular genome requires detailed computational analysis of whole genome sequence. Therefore, the role which helitrons have played in modelling non-model plant genomes is largely unknown. Cloning of the flowering gene GIGANTEA (GI) from a BAC library of the Pooideae grass Lolium perenne (perennial ryegrass) identified the target gene and several GI pseudogene fragments spanning the first five exons. Analysis of genomic sequence 5 and 3 of one these GI

Large-scale gene discovery has been performed for the grass fungal endophytes Neotyphodium coenophialum, Neotyphodium lolii, and Epichloë festucae. The resulting sequences have been annotated by comparison with public DNA and protein sequence databases and using intermediate gene ontology annotation tools. Endophyte sequences have also been analysed for the presence of simple sequence repeat and single nucleotide polymorphism molecular genetic markers. Sequences and annotation are maintained within a MySQL database that may be queried using a custom web interface. Two cDNA-based microarrays have been generated from this genome resource. They permit the interrogation of 3806 Neotyphodium genes (NchipTM microarray), and 4195 Neotyphodium and 920 Epichloë genes (EndoChipTM microarray), respectively. These microarrays provide tools for high-throughput transcriptome analysis, including genome-specific gene expression studies, profiling of novel endophyte genes, and investigation of the host ...
It was wonderful to enjoy the unseasonable cool fronts that came through our state in August, although, as we knew it would, the heat and humidity returned.. In September we should see even more relief from the heat. Still, daytime highs can continue to reach the 90s well into October.. During this transition period, warm-season and cool-season vegetables rub elbows in the garden. The warm-season vegetables, such as snap beans, okra, cucumbers, tomatoes, peppers and eggplants, will mostly finish up in November or early December as weather becomes colder. And cool-season vegetables and herbs are planted into the garden starting this month.. Vegetable and herb gardening seasons can be roughly divided into the cool season and the warm season. Vegetable gardeners must be especially attuned to the seasons and carefully observe the proper planting times for vegetables. Planting times relate to a variety of factors, but temperature is a major consideration.. Warm-season vegetables cannot withstand ...

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

Citation: Panaccione, D.G., Beaulieu, W.T., Cook, D. 2014. Bioactive alkaloids in vertically transmitted fungal endophytes. Functional Ecology. 28(2):299-314. Interpretive Summary: Plants form mutualistic symbioses with endophytic fungi that live inside the plant and cause no symptoms of infection. Key elements of these symbioses are vertical transmission of the fungus through seed of the host plant, a narrow host range, and production of bioactive metabolites by the fungus. Grasses frequently form symbioses with endophytic fungi belonging to the family Clavicipitaceae and produce four classes of bioactive alkaloidsergot alkaloids, lolines, indole-diterpenes, and peraminethat are distributed in different combinations among endophyte taxa, and result in significant impacts on insect and mammalian herbivores. Some plant species in the morning glory family (Convolvulaceae) also form symbioses with endophytic fungi of the Clavicipitaceae that produce ergot alkaloids and some species in this plant ...
