This report presents the description of a new Sporobolomyces species, Sp. odoratus sp. nov. The new species was characterized by DNA fingerprinting using the micro/minisatellite-primed PCR approach (MSP-PCR). A phylogenetic analysis using the D1/D2 region of the 26S rDNA revealed that Sp. odoratus belongs to a clade that includes Rhodosporidium fluviale and Sporidiobolus ruineniae. An integrated comparison with related species is presented. A number of presumptive strains of S. ruineniae were also investigated using the MSP-PCR method and 26S rDNA sequence analysis. Mating experiments revealed, for the first time, that S. ruineniae includes heterothallic strains, besides those already known to be self-fertile.
本报告描述了一种新的掷孢酵母属物种，即香掷孢酵母（Sporobolomyces odoratus sp. nov.）。该新物种通过使用微卫星/小卫星引物PCR方法（MSP-PCR）进行DNA指纹分析来表征。利用26S rDNA的D1/D2区域进行的系统发育分析表明，香掷孢酵母属于一个进化枝，其中包括河流红冬孢酵母（Rhodosporidium fluviale）和鲁氏掷孢酵母（Sporidiobolus ruineniae）。本文还对相关物种进行了综合比较。此外，还使用MSP-PCR方法和26S rDNA序列分析对一些推定的鲁氏掷孢酵母菌株进行了研究。交配实验首次揭示，除了已知的自育菌株外，鲁氏掷孢酵母还包括异宗配合菌株。
