The species corresponds to a complex, including two subspecies with validly published names, two proposed subspecies and two new species, and Recent studies suggested that this complex needed revision. We examined the taxonomic status of 144 strains isolated from a wide range of plant species, various geographical origins and waterways. Sequences of the , and housekeeping genes clustered 114 of these strains together within a not yet described clade. We sequenced eight strains of this clade and analysed them together with the 102 genomes available in the NCBI database. Phylogenetic analysis, average nucleotide identity calculation and DNA-DNA hybridization allowed us to differentiate seven clades. This led us to propose the elevation of subsp. to species level as sp. nov. (type strain CFBP 1878=LMG 5863=NCPPB 3839=ICMP 11533), the proposal of sp. nov. (type strain KKH3=LMG 26003 =KCTC 23131) and sp. nov. (type strain CFBP 6617= LMG 21371=NCPPB 4609), to emend the description of (type strain CFBP 2046=LMG 2404=NCPPB 312=ICMP 5702), and to propose a novel species, sp. nov (type strain CFBP6051= NCPPB 3387=ICMP 9168) which includes the strains previously described as 'Candidatus '. Phenotypic analysis performed using Biolog GENIII plates on eight strains of sp. nov. and related strains completed our analysis.
该物种对应于一个复杂的分类群,包括两个有效发表名称的亚种、两个拟议亚种和两个新种, 和 。最近的研究表明,这个分类群需要修订。我们检查了从广泛的植物物种、各种地理起源和水道中分离出来的 144 株菌株的分类地位。 、 和 看家基因的序列将这 144 株菌株中的 114 株聚集在一个尚未描述的分支内。我们对这个分支的 8 个菌株进行了测序,并与 NCBI 数据库中可用的 102 个基因组进行了分析。系统发育分析、平均核苷酸同一性计算和 DNA-DNA 杂交使我们能够区分出 7 个分支。这导致我们提议将亚种 提升到种的水平,即 sp. nov.(模式株 CFBP 1878=LMG 5863=NCPPB 3839=ICMP 11533),提议 sp. nov.(模式株 KKH3=LMG 26003=KCTC 23131)和 sp. nov.(模式株 CFBP 6617=LMG 21371=NCPPB 4609),修订 (模式株 CFBP 2046=LMG 2404=NCPPB 312=ICMP 5702)的描述,并提议一个新种, sp. nov.(模式株 CFBP6051=NCPPB 3387=ICMP 9168),其中包括以前描述为“Candidatus ”的菌株。使用 Biolog GENIII 板对 8 株 sp. nov.和相关菌株进行的表型分析完成了我们的分析。
