Abstract
, the largest order in , has a broad host range and inhabits host plants as epiphytes, endophytes, parasites and saprophytes. is a monophyletic family in , composed of species of deviated ecological background and morphological traits. In this study, we described a new fungal taxon under , based on root endophytic fungi recovered from the desert plant in Gansu Province, China. The taxon is characterised by simple, aseptate conidia and pycnidia in unusually small sizes. Multilocus phylogenetic analysis, based on ITS, LSU, SSU and TEF sequences and a morphology study indicated that the taxon represented a new genus within the and was named . Intriguingly, an intron of 355 bp in length located at site 453 on the ribosomal SSU gene was detected in one strain of . Sequence analysis and phylogenetic analysis indicated that the intron belongs to an intron position class (Pcl) restricted to . Phylogeny affiliated distribution of this Pcl was confined at the genus or lower level, suggesting a horizontal transmission pattern of this Pcl. This study established a new genus in and depicted the spread features of a less-documented Pcl amongst families with high resolution, which promotes our understanding of the origin and transmission mechanism of such mobile genetic elements.
