Regulation of Root Nodule Symbiosis by Soybean Rj Genotypes and Rhizobial Effectors.
Soybean (Glycine max) is one of the most important crops worldwide. Root nodule symbiosis between soybean and rhizobia has been extensively exami-ned due to its significance for agricultural productivity and environmental sustainability. Recent advances have enhanced our understanding of the soybean genotypes known as the Rj/rj genotypes, which play a critical role in regulating root nodule symbiosis. Furthermore, the function of rhizobium-secreted proteins, termed effectors, in eliciting specific responses in soybean Rj/rj genotypes has been elucidated. This review summarizes the involvement of soybean Rj/rj genotypes and their corresponding root nodule bacterial effectors in the regulation of nodule formation. We also discussed the potential for manipulating root nodule symbiosis by applying Rj/rj genotypes in soybean breeding programs, which may enhance nitrogen fixation efficiency and subsequently reduce the need for chemical fertilizers and greenhouse gas emissions from agricultural land.
