We describe the yeast genus Tortispora gen. nov., an early-diverging lineage in the Saccharomycetales that displays the formation of helical ascospores. The genus is based on 16 strains resembling Candida caseinolytica that were isolated from necrotic plant tissue in warm regions of the New World. Based on sequences of the D1/D2 domains of the nuclear large subunit rRNA gene, as well as other data, the strains are assigned to eight distinct species. The species are nutritionally specialized and share the unusual ability to hydrolyse casein and to grow on 1-butanol as sole carbon source. One species of the proposed new genus produces a simple ascus with a helical ascospore, whereas other species of the clade have failed to form ascospores. All species in the clade, including C. caseinolytica, are assigned to Tortispora gen. nov. The new binomials are Tortispora ganteri sp. nov., type species of the genus (SUB 86-469.5(T) = CBS 12581(T) = NRRL Y-17035(T)), Tortispora caseinolytica f.a., comb. nov. (UCD-FST 83-438.3(T) = CBS 7781(T) = NRRL Y-17796(T)), Tortispora mauiana f.a., sp. nov. (UWOPS 87-2430.3(T) = CBS 12803(T) = NRRL Y-48832(T)), Tortispora agaves f.a., sp. nov. (UWOPS 94-257.6(T) = CBS 12794(T) = NRRL Y-63662(T)), Tortispora sangerardonensis f.a., sp. nov. (UWOPS 00-157.1(T) = CBS 12795(T) = NRRL Y-63663(T)), Tortispora cuajiniquilana f.a., sp. nov. (UWOPS 99-344.4(T) = CBS 12796(T) = NRRL Y-63664(T)), Tortispora starmeri f.a., sp. nov. (G 91-702.5(T) = CBS 12793(T) = NRRL Y-63665(T)) and Tortispora phaffii f.a., sp. nov. (UWOPS 91-445.1(T) = CBS 12804(T) = NRRL Y-48833(T)). In addition, species formerly assigned to the genus Ascobotryozyma are reassigned to the genus Botryozyma. The genera Trigonopsis, Botryozyma and Tortispora are assigned to the family Trigonopsidaceae fam. nov.
我们描述了酵母属 Tortispora 属，这是一个在 Saccharomycetales 中早期分化的谱系，其特征是形成螺旋形的子囊孢子。该属基于 16 株类似于产朊假丝酵母的菌株，这些菌株是从新世界温暖地区的坏死植物组织中分离出来的。基于核大亚基 rRNA 基因的 D1/D2 结构域序列以及其他数据，这些菌株被分配到 8 个不同的种。这些种在营养上具有特异性，并且具有不寻常的水解酪蛋白的能力，并能够以 1-丁醇作为唯一的碳源生长。提议的新属的一个种产生具有螺旋形子囊孢子的简单子囊，而该分支的其他种未能形成子囊孢子。该分支中的所有种，包括产朊假丝酵母，都被分配到 Tortispora 属。新的双名法是 Ganteri Tortispora sp. nov.，属的模式种（SUB 86-469.5（T）= CBS 12581（T）= NRRL Y-17035（T）），产朊假丝酵母 f.a.，组合新名（UCD-FST 83-438.3（T）= CBS 7781（T）= NRRL Y-17796（T）），Mauiana Tortispora f.a.，新种（UWOPS 87-2430.3（T）= CBS 12803（T）= NRRL Y-48832（T）），Agaves Tortispora f.a.，新种（UWOPS 94-257.6（T）= CBS 12794（T）= NRRL Y-63662（T）），Sangerardonensis Tortispora f.a.，新种（UWOPS 00-157.1（T）= CBS 12795（T）= NRRL Y-63663（T）），Cuajiniquilana Tortispora f.a.，新种（UWOPS 99-344.4（T）= CBS 12796（T）= NRRL Y-63664（T）），Starmeri Tortispora f.a.，新种（G 91-702.5（T）= CBS 12793（T）= NRRL Y-63665（T））和 Phaffii Tortispora f.a.，新种（UWOPS 91-445.1（T）= CBS 12804（T）= NRRL Y-48833（T））。此外，以前被分配到 Ascobotryozyma 属的种被重新分配到 Botryozyma 属。Trigonopsis、Botryozyma 和 Tortispora 属被分配到新的 Trigonopsidaceae 科。
