Rhizobium hainanense sp. nov., Isolated from Tropical Legumes

Abstract

A fast-growing rhizobial group isolated from leguminous plants in Hainan Province, a tropical region of China, is proposed as a new Rhizobium species on the basis of 16S rRNA gene sequencing. DNA-DNA hybridization, and phenotypic characterization. This new species belongs to the phylogenetic branch which includes Rhizobium leguminosarum. We propose the name Rhizobium hainanense sp. nov. for this species. The strain CCBAU 57015 (166) is the type strain; it has been deposited in the culture collection of Beijing Agricultural University, People's Republic of China.
