Burkholderia phymatum Strains Capable of Nodulating Phaseolus vulgaris Are Present in Moroccan Soils

摘要

Phylogenetic analysis of 16S rRNA, nodC , and nifH genes of four bacterial strains isolated from root nodules of Phaseolus vulgaris grown in Morocco soils were identified as Burkholderia phymatum . All four strains formed N_(2)-fixing nodules on P. vulgaris and Mimosa , Acacia , and Prosopis species and reduced acetylene to ethylene when cultured ex planta .
