This study revealed additional genomic and taxonomic diversity of tumorigenic agrobacteria. Tumorigenic strains isolated from rhododendron represent a novel species of the genus Rhizobium for which the name Rhizobium rhododendri sp. nov. is proposed. Both species of the “tumorigenes” clade (R. rhododendri and R. tumorigenes), contain multipartite genomes. Synteny and phylogenetic analyses indicated that a large putative chromid of R. rhododendri resulted from the cointegration of an ancestral megaplasmid and two putative chromids, following its divergence from R. tumorigenes.

根瘤菌科“tumorigenes”进化枝的基因组学和杜鹃根瘤菌的描述。十一月

这项研究揭示了致瘤农杆菌的额外基因组和分类学多样性。从杜鹃花中分离出的致瘤菌株代表了根瘤菌属的一个新种，其名称为Rhizobium rhododendri sp.。十一月 被提议。“tumorigenes”进化枝（R. rhododendri和R. tumorigenes）的两个物种都包含多部分基因组。同线分析和系统发育分析表明， R. rhododendri的一个大的假定染色质是由一个祖先的巨质粒和两个假定的染色质的共整合产生的，继它与R. tumorigenes的分歧之后。
