Epichloë Festucae
''Epichloë'' is a genus of ascomycete fungi forming an endophytic symbiosis with grasses. Grass choke disease is a symptom in grasses induced by some ''Epichloë'' species, which form spore-bearing mats (stromata) on tillers and suppress the development of their host plant's inflorescence. For most of their life cycle however, ''Epichloë'' grow in the intercellular space of stems, leaves, inflorescences, and seeds of the grass plant without incurring symptoms of disease. In fact, they provide several benefits to their host, including the production of different herbivore-deterring alkaloids, increased stress resistance, and growth promotion. Within the family Clavicipitaceae, ''Epichloë'' is embedded in a group of endophytic and plant pathogenic fungi, whose common ancestor probably derived from an animal pathogen. The genus includes both species with a sexually reproducing (teleomorphic) stage and asexual reproduction, asexual, anamorphic species. The latter were previously p ...

Epichloë Typhina
''Epichloë typhina'' is a haploid sexual species in the fungal genus ''Epichloë''. It was Species description, originally described as a ''Sphaeria'' species. Today, however, it is classified in ''Epichloë''. A systemic grass symbiont first described as ''Sphaeria typhina'' by Christian Hendrik Persoon in 1798, and transferred to genus ''Epichloë'' in 1865, ''E. typhina'' forms an only partially resolved species complex within the ''Epichloë'' genus. ''Epichloë typhina'' is found in Europe, but has been introduced widely in North America and elsewhere. It lives in association with a large number of grass species from multiple genera, including ''Anthoxanthum odoratum'', ''Brachypodium'' ''phoenicoides'', ''Brachypodium pinnatum'', ''Dactylis glomerata'', ''Lolium perenne'', ''Milium effusum'', Timothy-grass, ''Phleum pratense'', ''Poa trivialis'', ''Poa silvicola'' and ''Puccinellia distans''. ''Epichloë typhina'' appears to be seed-transmissible only in ''Puccinellia d ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
