Actinomycete strain YU127-1T (T = type strain), which produces zoospores, was isolated from a soil sample. The aerial mycelium of this organism at maturity forms short chains of spores. The hyphae form coils, and sporangia are not observed. Strain YU127-1T contains glutamic acid, glucosamine, glycine, alanine, and meso-diaminopimelic acid in its cell wall (wall chemotype II), 3-O-methylmannose, mannose, xylose, and glucose as whole-cell sugars, meanaquinone 10(H4), and glycolyl cell wall polysaccharides and has a guanine-plus-cytosine content of 69.0 mol%. Mycolic acids are absent. Phosphatidylinositol and phosphatidylethanolamine are diagnostic phospholipids. The chemotaxonomic data, except for the lack of arabinose in the whole-cell sugars, indicate that this strain belongs to the family Micromonosporaceae. The morphological and physiological characteristics and chemotaxonomic and phylogenetic data for this strain differ from those of the previously described actinomycetes. We therefore propose a new genus, spirilliplanes, for this organism; the type species of the genus is Spirilliplanes yamanashiensis sp. nov., and the type strain of S. yamanashiensis is strain YU127-1 (= IFO 15828).
从土壤样本中分离出了能产生游动孢子的放线菌菌株YU127-1T（T = 模式菌株）。该菌株成熟时的气生菌丝形成短链孢子。菌丝形成螺旋状，未观察到孢子囊。菌株YU127-1T的细胞壁含有谷氨酸、葡糖胺、甘氨酸、丙氨酸和内消旋二氨基庚二酸（细胞壁化学型II），全细胞糖包括3-O-甲基甘露糖、甘露糖、木糖和葡萄糖，甲基萘醌10(H4)，以及糖基化细胞壁多糖，鸟嘌呤加胞嘧啶含量为 69.0 mol%。不存在分枝菌酸。磷脂酰肌醇和磷脂酰乙醇胺是诊断性磷脂。化学分类学数据表明，除了全细胞糖中缺乏阿拉伯糖外，该菌株属于小单孢菌科。该菌株与先前描述的放线菌在形态、生理特征以及化学分类学和系统发育数据方面存在差异。因此，我们为该菌株提议一个新属，螺旋平线菌属；该属的模式种是山梨螺旋平线菌（Spirilliplanes yamanashiensis）新种，山梨螺旋平线菌的模式菌株是YU127-1T菌株（= IFO 15828）。
