Rhizobium leguminosarum bv. viciae strains producing lipo-chitin oligosaccharides (LCOs) that are O-acetylated at the reducing terminus are required for nodulation of wild pea cultivars originating from Afghanistan that possess the recessive sym2A allele. The O-acetylation of the reducing sugar of LCOs is mediated by the bacterial nodX gene, which presumably encodes an acetyltransferase. We found that for nodulation on Afghan pea cultivars and sym2A introgression lines the nodX gene can be functionally replaced by the nodZ gene of Bradyrhizobium japonicum, which encodes a fucosyltransferase that fucosylates the reducing terminus of LCOs. The structure of the nodules, which were induced with normal frequency, was typical for effective pea nodules, and they fixed nitrogen with the same efficiency as nodules induced by nodX-carrying strains.
