Phylogenetic and population genetic analyses of Phaeosphaeria nodorum and its close relatives indicate cryptic species and an origin in the Fertile Crescent

Abstract: The origin of the fungal wheat pathogen Phaeosphaeria nodorum remains unclear despite earlier intensive global population genetic and phylogeographical studies. We sequenced 1683 bp distributed across three loci in 355 globally distributed Phaeosphaeria isolates, including 74 collected in Iran near the center of origin of wheat. We identified nine phylogenetically distinct clades, including two previously unknown species tentatively named P1 and P2 collected in Iran. Coalescent analysis indicates that P1 and P… Show more

“…Based on the evidence presented in this study, the taxonomic status of isolates recognized as T. discophora should be reconsidered. This trend is not only found in Thelonectria , but also in other genera of the Hypocreales [75][76], other ascomycetes [11], [77], and many other microorganisms. At the gross morphological level, Thelonectria discophora -like species might appear to be under morphological stasis or an example of many species showing a morphological convergence.…”

“…ToxA was later found in a third fungal pathogen species Phaeosphaeria avenaria tritici (McDonald et al ., ). Here, evidence of interspecific hybridization between P. nodorum and this sister species was postulated to be the mechanism of ToxA transfer (McDonald et al ., ).…”

“…As a result, such taxonomic features need to be supplemented with other characters like molecular markers that differentiate biological entities at the genetic level. Currently there is a growing interest to assess the genetic diversity of fungi including Fusaria based on sequence analysis (McDonald et al, 2012;Leavitt et al, 2013;Maphosa et al, 2016;Laraba et al, 2017).…”
