Abstract

The hydrogen uptake (Hup) system of Bradyrhizobium diazoefficiens recycles the H₂ released by nitrogenase in soybean nodule symbiosis, and is responsible for H₂-dependent chemolithoautotrophic growth. The strain USDA110 has two hup gene clusters located outside (locus I) and inside (locus II) a symbiosis island. Bacterial growth under H₂-dependent chemolithoautotrophic conditions was markedly weaker and H2 production by soybean nodules was markedly stronger for the mutant of hup locus I (ΔhupS₁L₁) than for the mutant of hup locus II (ΔhupS₂L₂). These results indicate that locus I is primarily responsible for Hup activity.
