(), a plant-pathogenic coryneform species includes five pathovars with valid names and a number of proposed – but unvalidated – new members. In this study, phenotypic features and DNA similarity indexes were investigated among all members. Results showed that the pv. strains causing bacterial canker of in the USA as well as the orange-/red-pigmented strains of pv. pathogenic on dry beans in Iran are too distinct from each other and from the type strain of the species to be considered members of . Hence, the latter two groups were elevated at the species level as sp. nov. (ATCC 9682 = CFBP 2403 = ICMP 2566 = LMG 3715 = NCPPB 854 as type strain), and sp. nov. (50R = CFBP 8819 = ICMP 22071 as type strain). Within the emended species comb. nov., yellow-pigmented strains causing bacterial wilt of dry beans and those causing bacterial canker of in Europe were retained as pv. and pv respectively; while taxonomic position of the sugar beet pathogen pv. ATCC BAA144 was confirmed. The newly described onion pathogen was also reclassified as pv with the pathotype strain LMG 32517. Furthermore, pv. causing bacterial leaf spot of malabar spinach () was transferred to pv. with ATCC BAA143 as pathotype.

多阶段研究意味着豆类病原体 Curtobacter flaccumfaciens pv. 的橙色/红色菌株的转移。flaccumfaciens 到一个新物种 C. aurantiacum sp。11 月，一品红病原体 C. flaccumfaciens pv. 升高。一品红到物种水平为 C. Poinsettiae sp。nov.，以及 C. albidum 与 C. citreum 的同义

()，一种植物致病性棒状杆菌属物种，包括五个具有有效名称的致病变种和一些拟议的（但未经验证的）新成员。本研究对所有成员的表型特征和DNA相似性指数进行了调查。结果表明，PV。在美国引起细菌性溃疡病的菌株以及橙色/红色的PV菌株。伊朗干豆上的致病菌彼此之间以及与被视为成员的物种的模式菌株差异太大。因此，后两组在物种水平上被提升为 sp。十一月 （ATCC 9682 = CFBP 2403 = ICMP 2566 = LMG 3715 = NCPPB 854 作为典型菌株）和 sp。十一月 （50R = CFBP 8819 = ICMP 22071 作为类型菌株）。内修正种梳。十一月，引起干豆青枯病的黄色菌株和引起欧洲细菌性溃疡病的菌株被保留为 pv。和 pv 分别；而甜菜病原体 pv 的分类位置。ATCC BAA144 已得到确认。新描述的洋葱病原体也被重新分类为 pv，其致病型菌株为 LMG 32517。引起马拉巴菠菜细菌性叶斑病的细菌性叶斑病（）被转移到光伏。以 ATCC BAA143 为致病型。
