Increased nodulation of soybean by a strain of Bradyrhizobium japonicum with altered tryptophan metabolism

A strain of Bradyrhizobium japonicum was isolated that accumulated anthranilic acid, indole, 3‐indoleacetic acid, 3‐indolelactic acid and 3‐indolepyruvic acid in culture. Such accumulations are indicative of altered tryptophan metabolism. Soybean plants inoculated with these bacteria formed more nodules (349 vs 159 per plant) and had more nodule mass (3.9 vs 2.2 g wet wt per plant) than plants inoculated with the wild‐type strain.
