Abstract

Three yeast isolates, NBRC 115909T, NBRC 115910 and NBRC 116270, were isolated from Trifolium pratense (red clover) flowers collected from Kisarazu, Chiba, Japan. Analysis of the sequences of the D1/D2 domains of the large subunit (LSU) rRNA gene and the internal transcribed spacer (ITS) regions revealed that these isolates represent a single novel species within the genus Starmerella. Also, no ascospore formation was observed. The yeast isolates were closely related to Starmerella vitae UWOPS 00-107.2T and Starmerella bombi NRRL Y-17081T. They differed from S. vitae, the most closely related species with a validly published name, by ten nucleotide substitutions with two gaps in the D1/D2 domains and 20 nucleotide substitutions in the ITS region. Moreover, the three isolates exhibited distinct phenotypic characteristics from the closely related species. Therefore, we suggest that these three isolates represent a novel species, designated as Starmerella kisarazuensis f.a., sp. nov. The holotype is NBRC 115909T (isotype: CBS 18485T).
