Rhizobium acaciae and R. anhuiense are the dominant rhizobial symbionts of Pisum sativum L. from Yunnan-Guizhou Plateau.

ABSTRACT:

Introduction

The aim of this study is to investigate the diversity and geographic distribution of pea-nodulating rhizobia in the subtropical region of Yunnan Province from Yunnan-Guizhou Plateau.

Methods and results

A total of 615 rhizobial isolates were obtained from root nodules of the trapping plants and characterized genetically and symbiotically. The isolates discriminated into 43 genotypes by PCR-RFLP of IGS DNA. Multiple locus sequence analysis based on 16S rRNA, recA, atpD, dnaK, and rpoB genes placed them into eight clusters corresponding to species R. acaciae, R. anhuiense, R. binae, R. bangladeshense, R. hidalgonense, and three suspected novel populations of Rhizobium genosp. I-III. R. acaciae was the dominan
