Two rhizobia strains,named T786 and T808,were isolated from the highland barley cultivation soil in Qamdo,Tibet,using R and M5 media at 4℃,respectively.After morphological,physiological,biochemical identification and 16S rRNA sequence analysis,strains T786 and T808 were preliminarily identified to genus Neorhizobium and Pararhizobium.The multiple sequence alignment results of 6 pairs housekeeping genes(atpD,recA,rpoB,thrC,glnII and glnA)in T786 and T808 showed that the similarity of these housekeeping genes and ANI values in strains T786 and T...
