The genus has important economic and ecological values. In 2016, we isolated a strain . After studying the phylogenetic relationship of , we believe that is an independent species and speculate that it is a natural nothospecies. Recently, the morphological characteristics and sequences of seven genes (ITS, LSU, β-tubulin, calmodulin, RNA polymerase II subunit, β-ketoacyl synthase, and mating-type locus 1-1) of 15 strains were analyzed, including sequencing of multiple clones of five protein genes in four strains. Two types of haplotypes (A and B) were observed in the five protein genes of . Haplotype A was closely related to , and haplotype B may be derived from an unknown species. The results demonstrated that including type strains may be a natural nothospecies. This study laid the foundation for further exploration of the genome, and the study may be of significant importance for the fermentation industry.
该属具有重要的经济和生态价值。2016年，我们分离出了一个菌株。在研究该菌株的系统发育关系后，我们认为它是一个独立的物种，并推测它是一个天然杂种。最近，对15个该菌株的七个基因（ITS、LSU、β-微管蛋白、钙调蛋白、RNA聚合酶II亚基、β-酮酰基合酶和交配型位点1-1）的形态特征和序列进行了分析，包括对四个该菌株中五个蛋白质基因的多个克隆进行测序。在该菌株的五个蛋白质基因中观察到了两种单倍型（A和B）。单倍型A与[某物种]密切相关，单倍型B可能来源于一个未知的[某物种]。结果表明，包括模式菌株在内的该菌株可能是一个天然杂种。本研究为进一步探索该菌株的基因组奠定了基础，该研究可能对该菌株的发酵工业具有重要意义。
