Description

Yu Kosulnikov and five co-authors profile in 2026 a soybean nodule bacterium strain, RZ300, bred to survive drying on seeds. Farmers coat legume seeds with such bacteria before sowing to fix nitrogen in the roots. Many cells die as the coat dries, which blunts the benefit.

Three production strains are tested on seeds of three soybean varieties at varied doses, drying heats, and protective coatings. Variety barely matters, while strain matters a great deal. RZ300 survives drying best of the three. Genome comparison with a weaker strain finds an extra gene, opgC, in RZ300 that may explain the edge. The strain suits commercial inoculants for dry seed handling.
