Differential regulation of the Epr3 receptor coordinates membrane-restricted rhizobial colonization of root nodule primordia

Abstract

TheLotus japonicus LysM receptor kinase EPR3 perceives rhizobial exopolysaccharides to initiate infection of the root epidermis. Here the authors show that EPR3 also mediates infection thread progression in the root cortex and show that key transcription factors that regulate symbiosis specify the expression of Epr3.
