Profundae diversitas: the uncharted genetic diversity in a newly studied group of fungal root endophytes.

ABSTRACT: Endophytes associated with crops have potential as beneficial inoculants in agriculture, but little is known about their genetic diversity and phylogenetic relationships. We carried out the first ever ecological and phylogenetic survey of the culturable fungal root endophytes of a wild barley species. Fungal root endophytes were isolated from 10 populations of wall barley (Hordeum murinum), and 112 taxa of fungi were identified based on internal transcribed spacer sequence similarity. We found representatives from 8 orders, 12 families and 18 genera. Within this group, only 34 isolates (30% of the total) could be confidently assigned to a species, and 23 of the isolates (21% of the total) had no significant match to anything deposited in GenBank (based on <85% sequence similarity).
