GmRj2/Rfg1 control of soybean–rhizobium–soil compatibility

Abstract

Coordinated evolution and mutual adaptation of soybean–rhizobium–soil (SRS) are crucial for soybean distribution, but the genetic mechanism involved had remained unclear. In a recent study, Li et al. identified a natural variant of the GmRj2/Rfg1 gene that affected the ability of soybean to adapt to distinct soil types by controlling soybean–rhizobium interaction, thus unravelling the mystery of SRS compatibility.
