BRADYRHIZOBIUM JAPONICUM NODULATION REGULATORY PROTEIN AND GENE.

摘要

regulatory genes for nodulation (nodd genes of bradyrhizobium japonicum strains have been isolated and sequenced. recombinant dna molecules and vectors containing these regulatory genes are described. these genes, molecules and vectors are useful in genetic engineering of strains of rhizobium and bradyrhizobium.a process is also described to implement the structural genes for selective gene expression in response to the application of chemical factors that induce nod genes of b. japonicum.
