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

et al. 2015

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). These results suggest a high proportion of novel fungi, with 28% not assigned to a known fungal order. This includes three endophytes that have been shown to significantly improve agronomic traits in cultivated barley. This study has, therefore, revealed a profound diversity of fungal root endophytes in a single wild relative of barley. Extrapolating from this, the study highlights the largely unknown, hugely diverse and potentially useful resource of crop wild relative endophytes.

Jacobsen, N, & Bothmer, R. von, 1995. Taxonomy in the Hordeum murinum complex (Poaceae). — Nord. J. Bot. 15: 449–458. Copenhagen. ISSN 0107–055X. Hordeum murinum as circumscribed here comprises ssp. glaucum (2x), ssp. murinum (4x), and ssp. leporinum (4x, 6x). Previous taxonomical treatments are reviewed as well as the more recent approaches, viz. numerical and statistical analyses, investigations of isoenzymes, rDNA, cpDNA, meiotic analyses, and chromosome banding patterns. A formal nomenclatural treatment is presented.

The demarcation of the Old World species in Hordeum L. section Hordeastrum Doell. has been the subject of considerable controversy. The present paper reports the results of a morphometric analysis of the wall and sea barleys (H. murinum L., H. marinum Huds., and their allies). A sample of 227 accessions was scored for 39 characters, and the resulting data matrix was divided into three groups on the basis of lodicules and cpiblast characters. These three groups were then subjected to several aspects of discriminant analysis (stepwise discriminant analysis, linear discriminant analysis, canonical analysis of discriminance, and nearest neighbor discriminant analysis) both on untransformed and log-transformed data. The results indicate that the wall and sea barleys consist of five distinct groups worthy of morphological specific rank. These correspond to H. marinum sensu stricto, H. geniculatum All., H. glaucum Steudel. H. murinum sensu stricto, and H. leporinum Link. Ranges for 37 characters within these five taxa are presented. A key to the five species and one hybrid (reported in the first paper of this series) is supplied. Our conclusions are discussed in the context of various taxonomic treatments of the group.
