Perennial ryegrass endophytes (Neotyphodium lolii) together with the neurotoxin lolitrem B and the vasoconstrictor ergovaline are responsible for, among others, hypersensitivity in ruminants, impaired heat stress recognition, and vasoconstriction. (thebeefsite.com)
Perennial ryegrass endophyte (Neotyphodium lolii) alkaloids are frequently present in pastures containing the neurotoxin lolitrem B, together with the vaso-constrictor ergovaline, at levels associated with ryegrass staggers, heat stress, ill-thrift and lowered milk production. (thebeefsite.com)
Perennial ryegrass (Lolium perenne) is often infected with the fungal-endophyte Neotyphodium lolii. (researchgate.net)
Outbreaks, in summer and autumn, occur only on pasture in which endophyte (Neotyphodium lolii)-infected perennial ryegrass (Lolium perenne) predominates and usually on which animals are grazed intensively. (keyopinionleaders.com)
One is liver damage with resulting photosensitization (caused by a fungus called Pithomyces chartarum growing on the ryegrass) and the other is incoordination, caused by mycotoxins produces by the endophytic fungus originally called Acrimonium lolii and now called neotyphodium lolii. (equimed.com)
There are several neurotoxins responsible for these signs, due to the alkaloids produced in perennial and hybrid ryegrasses infected with the endophytic fungus Neotyphodium lolii. (equimed.com)
The ryegrass endophyte (Neotyphodium lolii) is not present in Italian ryegrass. (progressiveseeds.com.au)
Cloning and analysis of a plant-induced non-ribosomal peptide synthetase (NRPS) gene from Neotyphodium lolii and analysis of the E. festucae E2368 genome sequence revealed a complex gene cluster for ergot alkaloid biosynthesis. (massey.ac.nz)
Endophytes4
Loline alkaloids (LA), which are 1-aminopyrrolizidines with an oxygen bridge, are produced by Epichloë (anamorph= Neotyphodium ) species, endophytes of grasses. (uky.edu)
The symbioses between many Pooideae grasses and Neotyphodium fungal endophytes are mutualistic relationships with both partners gaining benefits. (oregonstate.edu)
For detailed information on tall fescue and Neotyphodiumendophytes (see Chapter 2 ). (oregonstate.edu)
Clavicipitaceous fungal endophytes of the genera Epichloë and Neotyphodium form symbioses with grasses of the family Pooideae in which they can synthesise an array of bioprotective alkaloids. (massey.ac.nz)
Coenophialum3
Neotyphodium starrii is closely related to N. coenophialum, but the taxonomic status within Epichloë (whether it is a distinct species or not) is unclear (nomen dubium). (wikipedia.org)
The purpose of this review is to provide a pictorial representation of the nature of the symbioses between tall fescue and Neotyphodium coenophialum (Morgan-Jones and Gams) Glenn, Bacon, and Hanlin , and also that of other asexual Neotyphodium species and their close sexual relatives, the Epichloë species, with their respective host grasses.

Fescue hay infected with the endophyte fungus Neotyphodium coenophialum causes reproductive problems in mares if fed during late pregnancy. (missouri.edu)

Neotyphodium is a genus of endophytic fungi symbiotic with grasses. (wikipedia.org)

Uncinatum2
Suppression subtractive hybridization PCR was used to isolate transcripts up-regulated during loline alkaloid production in cultures of Neotyphodium uncinatum . (uky.edu)
Differential expression of these two genes in LA-producing cultures of N. uncinatum was confirmed, and in a survey of 23 isolates from 21 Neotyphodium and Epichloë species these two genes strictly correlated with LA production. (uky.edu)
Species1
Two species of unclear position were excluded from this treatment: Neotyphodium chilense from Chile should be treated as Acremonium chilense since the previous transfer to Neotyphodium is untested. (wikipedia.org)
