Phylogenomics of asexual Epichloe fungal endophytes forming associations with perennial ryegrass.

ABSTRACT:

Background

Perennial ryegrass (Lolium perenne L.) is one of the most important species for temperate pastoral agriculture, forming associations with genetically diverse groups of mutualistic fungal endophytes. However, only two taxonomic groups (E. festucae var. lolii and LpTG-2) have so far been described. In addition to these two well-characterised taxa, a third distinct group of previously unclassified perennial ryegrass-associated endophytes was identified as belonging to a putative novel taxon (or taxa) (PNT) in a previous analysis based on simple sequence repeat (SSR) marker diversity. As well as genotypic differences, distinctive alkaloid production profiles were observed for members of the PNT group.
