Spontaneously Produced Lysogenic Phages Are an Important Component of the Soybean <i>Bradyrhizobium</i> Mobilome.

ABSTRACT: The ability of Bradyrhizobium spp. to nodulate and fix atmospheric nitrogen in soybean root nodules is critical to meeting humanity's nutritional needs. The intricacies of soybean bradyrhizobia-plant interactions have been studied extensively; however, bradyrhizobial ecology as influenced by phages has received somewhat less attention, even though these interactions may significantly impact soybean yield. In batch culture, four soybean bradyrhizobia strains, Bradyrhizobium japonicum S06B (S06B-Bj), B. japonicum S10J (S10J-Bj), Bradyrhizobium diazoefficiens USDA 122 (USDA 122-Bd), and Bradyrhizobium elkanii USDA 76^T (USDA 76-Be), spontaneously (without apparent exogenous chemical or physical induction) produced tailed phages throughout the growth cycle; for three strains,
