Are the genus Moniliella and Trichosporonoides closely related in molecular taxonomic relationship\ulcorner

The molecular taxonomic relationship of nine species in the genus Moniliella Stolk & Dakin and Trichosporonoides Haskins & Spencer and six species of other yea나-like fungi was examined by sequencing analysis of large subunit rDNA D1/D2 variable domain. The fifteeen species fell into two major groups corresponding with their genetic relationships. The nine species of the genus Moniliella and Trichosporonoides were placed at the same cluster. similarity values based on the D1/D2 domain sequences were 45.4-100% among species of genus Moniliella, 45.2-84.4% among genus Trichosporonoides species, and 45.6-90.1% among species of genus Moniliella and Trichosporonoides. Identical sequence similarity was observed between M. suaveolens var. nigra and M. suaveolens. A colse relationship of M. mellis. and M. acetoabutens is observed. The result of this study provided and insight into the genetic origins of genus Moniliella and Trichosporonoides species as well as their genetic relationships. Genus Moniliella and Trichosporonoides are closely related to each other based on sequence analysis of the large subunit rDNA D1/D2 region and we suggest combination of the genus Moniliella and Trichosporonoides to single genus.
