Inoculation with Sinorhizobium meliloti RMBPC-2 Increases Alfalfa Yield Compared with Inoculation with a Nonengineered Wild-Type Strain

Abstract

Inoculation of alfalfa seeds with any of three recombinant strains of Sinorhizobium meliloti significantly increased overall plant biomass compared with inoculation with the wild-type strains over a 3-year period at three locations. A high proportion of nodules were occupied by the inoculum strains throughout the 3-year period.
