Physical and genetic mapping in the grasses Lolium perenne and Festuca pratensis. (1/90)
A single chromosome of the grass species Festuca pratensis has been introgressed into Lolium perenne to produce a diploid monosomic substitution line 2n = 2x = 14. In this line recombination occurs throughout the length of the F. pratensis/L. perenne bivalent. The F. pratensis chromosome and recombinants between it and its L. perenne homeologue can be visualized using genomic in situ hybridization (GISH). GISH junctions represent the physical locations of sites of recombination, enabling a range of recombinant chromosomes to be used for physical mapping of the introgressed F. pratensis chromosome. The physical map, in conjunction with a genetic map composed of 104 F. pratensis-specific amplified fragment length polymorphisms (AFLPs), demonstrated: (1) the first large-scale analysis of the physical distribution of AFLPs; (2) variation in the relationship between genetic and physical distance from one part of the F. pratensis chromosome to another (e.g., variation was observed between and within chromosome arms); (3) that nucleolar organizer regions (NORs) and centromeres greatly reduce recombination; (4) that coding sequences are present close to the centromere and NORs in areas of low recombination in plant species with large genomes; and (5) apparent complete synteny between the F. pratensis chromosome and rice chromosome 1. (+info)Diurnal variation in uptake and xylem contents of inorganic and assimilated N under continuous and interrupted N supply to Phleum pratense and Festuca pratensis. (2/90)
Compensation by dark-period uptake of NH(4)(+) and NO(3)(-) in the grasses Phleum pratense L. and Festuca pratensis Huds. following N deprivation during the preceding light period was investigated in flowing solution culture under an artificial 10/14 h light/dark cycle. N was supplied as either NO(3)(-), NH(4)(+) or NH(4)NO(3) at 20+/-5 mmol m(-3), available continuously or only during the dark period, for 5-10 d. Intermittent N supply did not affect total daily N uptake, growth rate or net partitioning of dry matter. Net uptake and influx of NO(3)(-) varied similarly throughout the diurnal cycle when NO(3)(-) was supplied continuously, with a marginal contribution by NO(3)(-) efflux. Influx was significantly higher and efflux slightly higher following interruption of NO(3)(-) supply during the light period. Nitrate accounted for 80% of N in xylem exudate except between hours 6-9 of the light period when the amino acid concentration increased 3-fold, primarily as glutamine. Diurnal variation in relative NO(3)(-) uptake exhibited five phases of constant acceleration/deceleration, described reasonably well assuming NO(3)(-) influx was subject to metabolic co-regulation by NO(3)(-) and amino acid levels in the cytoplasmic compartment of the roots. Accordingly, influx is determined by variation in root NO(3)(-) levels throughout the dark period and the first half of the light period, but is down-regulated by increased amino acid levels during the second half of the light period. The sharp light/dark transitions affect transpiration rate and hence xylem N flux which, in turn, affect NO(3)(-) levels in the cytoplasmic compartment of the roots and the rate of NO(3)(-) assimilation in the shoot. (+info)Rathayibacter caricis sp. nov. and Rathayibacter festucae sp. nov., isolated from the phyllosphere of Carex sp. and the leaf gall induced by the nematode Anguina graminis on Festuca rubra L., respectively. (3/90)
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. (+info)Changes in microbial community composition and function during a polyaromatic hydrocarbon phytoremediation field trial. (4/90)
The purpose of this study was to investigate the mechanism by which phytoremediation systems promote hydrocarbon degradation in soil. The composition and degradation capacity of the bulk soil microbial community during the phytoremediation of soil contaminated with aged hydrocarbons was assessed. In the bulk soil, the level of catabolic genes involved in hydrocarbon degradation (ndoB, alkB, and xylE) as well as the mineralization of hexadecane and phenanthrene was higher in planted treatment cells than in treatment cells with no plants. There was no detectable shift in the 16S ribosomal DNA (rDNA) composition of the bulk soil community between treatments, but there were plant-specific and -selective effects on specific catabolic gene prevalence. Tall Fescue (Festuca arundinacea) increased the prevalence of ndoB, alkB, and xylE as well as naphthalene mineralization in rhizosphere soil compared to that in bulk soil. In contrast, Rose Clover (Trifolium hirtum) decreased catabolic gene prevalence and naphthalene mineralization in rhizosphere soil. The results demonstrated that phytoremediation systems increase the catabolic potential of rhizosphere soil by altering the functional composition of the microbial community. This change in composition was not detectable by 16S rDNA but was linked to specific functional genotypes with relevance to petroleum hydrocarbon degradation. (+info)Use of nonergot alkaloid-producing endophytes for alleviating tall fescue toxicosis in sheep. (5/90)
Nonergot alkaloid-producing endophytes from New Zealand were inserted into tall fescue (Festuca arundinacea) cultivars in an attempt to address the problem of fescue toxicosis in grazing sheep. A 3-yr grazing study was conducted to determine lamb performance and to evaluate toxicosis in lambs grazing nonergot alkaloid-producing endophyte-infected (AR542 or AR502), endophyte-free (E-), or wild-type toxic endophyte-infected (E+) Jesup tall fescue or nonergot alkaloid-producing endophyte-infected (AR542) Georgia-5 tall fescue. Replicated 0.11-ha tall fescue paddocks were established at the central Georgia Branch Station during September 1997 and stocked with lambs from spring 1998 through autumn 2000. Mean ergot alkaloid concentrations were higher (P < 0.01) in E+ forage than in AR542, AR502, and E- tall fescue, and ergot alkaloid concentrations in E- plants and plants infected with AR542 and AR502 were low. Forage availability did not differ (P = 0.92) across treatments during autumn and was higher (P < 0.05) in Georgia-5 AR542 than in Jesup AR502 and E+ pastures. Initial serum prolactin (PRL) concentrations did not differ (P = 0.58) across treatments during autumn, but were higher on Jesup AR542 than E+ during spring. Post-treatment serum PRL concentrations were depressed (P < 0.01) on E+ compared with AR542, AR502, and E- in both spring and autumn. Signs of heat stress were observed in E+ lambs during periods of high ambient temperatures. Mean post-treatment rectal temperature and mean stocking rate exhibited treatment x year interactions (P < 0.05). Lamb ADG was higher (P < 0.05) on AR542, AR502, and E- than on E+ tall fescue. Similarly, gain/hectare was higher (P < 0.015) on AR542, AR502, and E- than on E+. Tall fescue pastures containing AR542 and AR502 endophytes yielded lamb performance that did not differ from that on E- tall fescue and which was superior to performance on E+ tall fescue. Depressed PRL concentrations and elevated rectal temperatures as indicators of toxicosis were evident only in lambs grazing E+ tall fescue, suggesting that nonergot alkaloid-producing endophyte-infected tall fescue is a viable alternative for alleviating tall fescue toxicosis. (+info)Growth of endophyte, Neotyphodium, and its host plant, tall fescue (Festuca arundinacea), under 3D-clinorotation. (6/90)
Growth of a filamentous fungus endophyte, Neotyphodium, and its host plant, tall fescue, Festuca arundinacea, was examined during the seed germination process under pseudo-microgravity [correction of micrgravity] generated by three dimensional (3D-) clinorotation. The shoot growth of tall fescue infected with the endophyte was remarkably suppressed on a 3D-clinostat compared with that of the ground control. Without being infected, shoot growth of tall fescue was not strongly affected by the 3D-clinorotation. Many aggregated hyphae were observed in the plant seed incubated for 1-day on the 3D-clinostat [correction of clinost] than in those kept on the ground. These results indicate that the clinorotation induces responses in the endophyte and its host plant different from those under normal gravity. (+info)Use of nonergot alkaloid-producing endophytes for alleviating tall fescue toxicosis in stocker cattle. (7/90)
Grazing studies were conducted to determine cattle growth performance, evaluate toxicosis, and compare grazing behavior in stocker cattle grazing nonergot alkaloid-producing endophyte-infected (AR542 or AR502), endophyte-free (E-), or wild-type toxic endophyte-infected (E+) Jesup, Georgia-5, and Kentucky-31 tall fescue. Replicated 0.81-ha tall fescue paddocks were established at the Central Georgia Branch Station at Eatonton and the Northwest Georgia Branch Station at Calhoun during October 1998 and were stocked with beef cattle for autumn and spring periods from fall 1999 through spring 2002. Mean ergot alkaloid concentrations were higher (P < 0.01) on E+ pastures than the other treatments at both locations. At Calhoun and Eatonton, post-treatment serum prolactin concentrations were decreased (P < 0.01) on E+ compared with AR542, AR502, and E- tall fescue. Cattle on AR542, AR502, and E- pastures had lower (P < 0.05) post-treatment rectal temperatures than cattle grazing E+ tall fescue during spring at Eatonton and Calhoun. Calf ADG was higher (P < 0.05) on AR542, AR502, and E- as compared with E+ tall fescue during autumn and spring grazing at Eatonton, and at Calhoun, cattle on E+ pastures had lower (P < 0.05) ADG in both autumn and spring. Gain/hectare was higher (P < 0.05) on AR542, AR502, and E- than on E+ during autumn at Eatonton and during spring at both locations. In autumn at Calhoun, gain/hectare was greater (P < 0.05) on AR502 and E- compared with E+ tall fescue. During April, May, and June, cattle grazing E+ pastures at Eatonton spent more (P < 0.01) time idling, more (P < 0.01) time standing, and used more (P < 0.01) water than cattle on AR542 and E- tall fescue. Daily prehensions and biting rate were each higher (P < 0.01) on AR542 and E- tall fescue than E+ tall fescue in both grazing seasons. There were no differences among pasture treatments for bite size in either spring (P = 0.50) or autumn (P = 0.34). Steers grazing E+ pastures had lower DMI than steers grazing AR542 and E- pastures during spring (P < 0.10) and lower DMI than steers grazing E- pastures during autumn (P < 0.05). Daily steer water usage was decreased (P < 0.10) in E+ pastures compared with AR542 and E- pastures during late fall. These results indicate that nonergot alkaloid-producing endophyte technology is a promising option for alleviating tall fescue toxicosis in stocker cattle. (+info)Growth rate and physiology of steers grazing tall fescue inoculated with novel endophytes. (8/90)
Cattle grazing tall fescue (Festuca arundinacea Schreb.) often develop fescue toxicosis. This condition is thought to be caused by ergot alkaloids produced by the endophyte Neotyphodium coenophialum. Endophytes from wild tall fescue plants, which do not produce ergot alkaloids, were transferred into the endophyte-free tall fescue germplasm, HiMag. The novel associations also lacked the ability to produce ergot alkaloids. Our objective was to determine whether cattle grazing these novel endophyte associations showed signs of fescue toxicosis. At the Fayetteville, Arkansas location, tester steers (n = 72) were assigned to one of four pasture treatments: endophyte-free HiMag tall fescue (HiMag-); 'Kentucky-31' tall fescue infected with its native, toxic endophyte (KY+); and two novel endophyte-infected tall fescue associations, HiMag4 and HiMag9. At the Mount Vernon, Missouri location, steers (n = 54) were used to test three of the four cultivars (HiMag9 was not tested). Ergot alkaloid concentrations in the forage of HiMag4 and HiMag9 were low or undetectable. Respiration rate, rectal temperature, ADG, and hair scores were measured during the grazing period. Blood was collected via jugular venipuncture and used for prolactin, aspartate aminotransferase, alkaline phosphatase (ALP), lactate dehydrogenase (LDH), cholesterol, triglyceride, and creatinine analysis. Weight gains by steers grazing HiMag4 and HiMag9 did not differ from those of steers grazing HiMag-, but were greater than gains (P < 0.05) by steers on the KY+ treatment. Steers grazing KY+ had higher (P < 0.05) respiration rates, rectal temperatures, and hair scores than did steers grazing novel endophyte and HiMag- pastures. Prolactin, ALP, cholesterol, LDH, and triglycerides all were suppressed (P < 0.05) in steers grazing KY+ compared with steers grazing novel endophyte and HiMag- pastures. Steers grazing the novel endophyte tall fescues did not suffer from the decreased weight gains and toxicities associated with fescue toxicosis, resulting in enhanced animal production. (+info)I apologize for any confusion, but "Festuca" is not a medical term. It is actually the genus name for a group of plants commonly known as fescue grasses. These grasses are often used in lawns, pastures, and meadows. If you have any questions about a medical term or concept, I would be happy to help if I can!
"Lolium" is not a term commonly used in medical definitions. It is actually the genus name for a group of plants that are more commonly known as ryegrasses. These plants belong to the family Poaceae and include several species that are widely used as pasture, hay, or lawn grasses.
While not directly related to human health, these plants can have indirect effects on health, particularly in agricultural settings. For example, certain ryegrass species can host a parasitic nematode called "Haemonchus contortus," which can infect and cause disease in livestock that graze on the grass.
However, without further context, it's challenging to provide a specific medical definition for "Lolium." If you have more information or if this term is being used in a specific medical context, please provide those details so I can give a more accurate response.
Poaceae is not a medical term but a taxonomic category, specifically the family name for grasses. In a broader sense, you might be asking for a medical context where knowledge of this plant family could be relevant. For instance, certain members of the Poaceae family can cause allergies or negative reactions in some people.
In a medical definition, Poaceae would be defined as:
The family of monocotyledonous plants that includes grasses, bamboo, and sedges. These plants are characterized by narrow leaves with parallel veins, jointed stems (called "nodes" and "internodes"), and flowers arranged in spikelets. Some members of this family are important food sources for humans and animals, such as rice, wheat, corn, barley, oats, and sorghum. Other members can cause negative reactions, like skin irritation or allergies, due to their silica-based defense structures called phytoliths.
"Acremonium" is a genus of filamentous fungi that are commonly found in soil, decaying vegetation, and water. Some species of Acremonium can cause infections in humans, particularly in individuals with weakened immune systems. These infections can affect various organs and tissues, including the skin, nails, lungs, and eyes.
The medical definition of "Acremonium" is therefore a type of fungus that can cause a variety of infectious diseases, particularly in immunocompromised individuals. It's important to note that Acremonium infections are relatively rare, but they can be serious and require prompt medical treatment.
Epichloe is a genus of fungi that are commonly found as endophytes (symbiotic fungi living inside plant tissues) in grasses. These fungi can form mutualistic relationships with their host plants, providing them with resistance to various stressors such as drought, pests, and pathogens. Some Epichloe species can also produce alkaloids that are toxic to livestock, which can have both positive and negative effects on the animals that graze on the grasses.
Epichloe fungi typically infect the above-ground tissues of their host plants, such as leaves and stems, and can form visible structures called sclerotia, which are compact masses of fungal tissue that can survive in the soil for extended periods. These sclerotia can serve as a source of infection for new grass hosts, allowing the Epichloe fungi to spread throughout populations of grasses.
Overall, Epichloe fungi play important roles in the ecology and evolution of grassland ecosystems, and have potential applications in agriculture and conservation.
Ergotism is a condition that results from the consumption of ergot alkaloids, which are found in ergot fungus that infects grains such as rye. There are two types of ergotism: convulsive and gangrenous. Convulsive ergotism can cause seizures, muscle spasms, vomiting, and mental disturbances. Gangrenous ergotism, on the other hand, can lead to constriction of blood vessels, resulting in dry gangrene of the extremities, which can ultimately require amputation. Ergotism has been known since ancient times and was once a significant public health problem before modern agricultural practices were implemented.
I'm sorry for any confusion, but "Poa" is not a medical term. It is a genus of grasses commonly known as meadow grass or bluegrass. If you have misspelled or are thinking of a different term, please provide more context so I can give you a more accurate response.
Plant poisoning is a form of poisoning that occurs when someone ingests, inhales, or comes into contact with any part of a plant that contains toxic substances. These toxins can cause a range of symptoms, depending on the type and amount of plant consumed or exposed to, as well as the individual's age, health status, and sensitivity to the toxin.
Symptoms of plant poisoning may include nausea, vomiting, diarrhea, abdominal pain, difficulty breathing, skin rashes, seizures, or in severe cases, even death. Some common plants that can cause poisoning include poison ivy, poison oak, foxglove, oleander, and hemlock, among many others.
If you suspect plant poisoning, it is important to seek medical attention immediately and bring a sample of the plant or information about its identity if possible. This will help healthcare providers diagnose and treat the poisoning more effectively.
"Neotyphodium" is not a medical term, but rather it is a genus of fungi that belongs to the family Clavicipitaceae. These endophytic fungi form mutualistic symbiotic relationships with various grass species, including important forage and turfgrasses. They colonize the interior of grass leaves and stems without causing apparent harm to the host plant, while receiving nutrients in return. Some Neotyphodium species produce alkaloids, which can provide the host grass with resistance to insect pests and certain diseases. However, these alkaloids may have negative effects on livestock that graze on the infected grasses, causing various toxicities or neurological disorders.
Hypocreales is an order of fungi in the class Sordariomycetes. This group includes many species that are saprophytic (growing on dead or decaying organic matter) as well as pathogenic, causing various diseases in plants and animals. Some notable members of Hypocreales include the genera Trichoderma, Hypocrea, Nectria, and Fusarium. These fungi are characterized by their perithecial ascomata (sexual fruiting bodies) and often produce colorful, flask-shaped structures called ascostromata. Some species in this order produce toxic compounds known as mycotoxins, which can have harmful effects on humans and animals if ingested or inhaled.
Ergotamines are a type of medication that is derived from the ergot fungus (Claviceps purpurea). They are primarily used to treat migraines and cluster headaches. Ergotamines work by narrowing blood vessels around the brain, which helps to alleviate the symptoms of migraines and headaches.
Ergotamines are available in various forms, including tablets, suppositories, and injectable solutions. They can be taken orally, rectally, or intravenously, depending on the severity of the symptoms and the patient's medical history. Ergotamines should be used with caution, as they can cause serious side effects such as nausea, vomiting, muscle pain, and weakness.
Ergotamines are also used in the treatment of other conditions, including postpartum hemorrhage, heart failure, and high blood pressure during pregnancy. However, their use in these conditions is typically reserved for cases where other treatments have been ineffective or contraindicated.
It's important to note that ergotamines can interact with a variety of medications, including certain antidepressants, antibiotics, and HIV medications. Therefore, it's essential to inform your healthcare provider about all the medications you are taking before starting treatment with ergotamines.
Ergot alkaloids are a type of chemical compound that is produced naturally by certain fungi belonging to the genus Claviceps. These alkaloids are most famously known for being produced by the ergot fungus (Claviceps purpurea), which infects cereal grains such as rye and causes a condition known as ergotism in humans and animals that consume the contaminated grain.
Ergot alkaloids have a complex chemical structure and can have various effects on the human body. They are known to act as powerful vasoconstrictors, which means that they cause blood vessels to narrow and can increase blood pressure. Some ergot alkaloids also have psychoactive effects and have been used in the past for their hallucinogenic properties.
In modern medicine, certain ergot alkaloids are used in the treatment of various conditions, including migraines and Parkinson's disease. However, these compounds can be highly toxic if not used properly, and their use must be carefully monitored to avoid serious side effects.
'Carex plant' is a genus of small perennial plants that are commonly known as sedges. These plants belong to the family Cyperaceae and there are over 2,000 different species found worldwide. Carex plants can vary in size, shape, and appearance depending on the specific species, but they generally have narrow, grass-like leaves and triangular stems.
Some Carex species produce flowers and seeds, while others reproduce through rhizomes or underground stems. These plants are often found growing in wetlands, marshes, and other moist environments, although some species can tolerate drier conditions as well. In a medical context, certain Carex species may have potential medicinal uses, such as anti-inflammatory or diuretic properties, but more research is needed to confirm their effectiveness and safety.
Animal feed refers to any substance or mixture of substances, whether processed, unprocessed, or partially processed, which is intended to be used as food for animals, including fish, without further processing. It includes ingredients such as grains, hay, straw, oilseed meals, and by-products from the milling, processing, and manufacturing industries. Animal feed can be in the form of pellets, crumbles, mash, or other forms, and is used to provide nutrients such as energy, protein, fiber, vitamins, and minerals to support the growth, reproduction, and maintenance of animals. It's important to note that animal feed must be safe, nutritious, and properly labeled to ensure the health and well-being of the animals that consume it.

- The first major monograph on the genus was Hackel's "Monographia Festucarum Europaearum" in 1882. (wikipedia.org)
- The annual habit and shorter anthers of Vulpia has since been enough to distinguish Vulpia as a separate genus from Festuca. (wikipedia.org)

Drymeja2
- Festuca drymeja Mert. (itis.gov)
- As it is fairly well established that L. pratense is one progenitor to 4 x F. arundinaceum , as F. scariosa is to L. mairei , they examined the crossablility of these two known progenitors with other Festuca diploids in sections Montanae ( F. donax , F. drymeja Mert. (oregonstate.edu)
Foliage1
- The grass like foliage on this Festuca is an eye catching silvery blue in colour, becoming more intense in the sun and turning a greener colour in Winter. (plants2gardens.com)

- Native Festuca heterophylla grows in open forests, forest edges, and on shrubby slopes (Barkworth et al. (idseed.org)
Turf1
- Other subgenera of Festuca also are very important as pasture in Europe and as turf worldwide. (oregonstate.edu)
Bisexual1
- bisexual, dioecious in Festuca kingii . (berkeley.edu)
Characteristics1
- The ancient group has produced various segregates that possess more advanced characteristics than Festuca, including racemose inflorescences and more annual habits. (wikipedia.org)
