Abstract

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. A detailed phylogenetic analysis of perennial ryegrass-associated endophytes using components of whole genome sequence data was performed using complete sequences of 7 nuclear protein-encoding genes. Three independently selected genes (encoding a DEAD/DEAH box helicase [Sbp4], a glycosyl hydrolase [family 92 protein] and a MEAB protein), none of which have been previously used for taxonomic studies of endophytes, were selected together with the frequently used 'house-keeping' genes tefA and tubB (encoding translation elongation factor 1-α and β-tubulin, respectively). In addition, an endophyte-specific gene (perA for peramine biosynthesis) and the fungal-specific MT genes for mating-type control were included. The results supported previous phylogenomic inferences for the known species, but revealed distinctive patterns of diversity for the previously unclassified endophyte strains, which were further proposed to belong not one but two distinct novel taxa. Potential progenitor genomes for the asexual endophytes among contemporary teleomorphic (sexual Epichloë) species were also identified from the phylogenetic analysis. Unique taxonomic status for the PNT was confirmed through comparison of multiple nuclear gene sequences, and also supported by evidence from chemotypic diversity. Analysis of MT gene idiomorphs further supported a predicted independent origin of two distinct perennial ryegrass-associated novel taxa, designated LpTG-3 and LpTG-4, from different members of a similar founder population related to contemporary E. festucae. The analysis also provided higher resolution to the known progenitor contributions of previously characterised perennial ryegrass-associated endophyte taxa.

Attention Score in Context

This research output has an Altmetric Attention Score of 4. This is our high-level measure of the quality and quantity of online attention that it has received. This Attention Score, as well as the ranking and number of research outputs shown below, was calculated when the research output was last mentioned on 06 August 2020.
All research outputs
#5,480,370
of 18,523,374 outputs
Outputs from BMC Evolutionary Biology
#1,296
of 2,836 outputs
Outputs of similar age
#70,771
of 242,745 outputs
Outputs of similar age from BMC Evolutionary Biology
#1
of 1 outputs
Altmetric has tracked 18,523,374 research outputs across all sources so far. This one has received more attention than most of these and is in the 70th percentile.
So far Altmetric has tracked 2,836 research outputs from this source. They typically receive a lot more attention than average, with a mean Attention Score of 10.8. This one has gotten more attention than average, scoring higher than 53% of its peers.
Older research outputs will score higher simply because they've had more time to accumulate mentions. To account for age we can compare this Altmetric Attention Score to the 242,745 tracked outputs that were published within six weeks on either side of this one in any source. This one has gotten more attention than average, scoring higher than 70% of its contemporaries.
We're also able to compare this research output to 1 others from the same source and published within six weeks on either side of this one. This one has scored higher than all of them
