متن کاملRhizobial Nodulation Genes nodIJ
Although many aand some b-proteobacterial species are symbiotic with legumes, the evolutionary origin of nitrogenfixing nodulation remains unclear. We examined aand b-proteobacteria whose genomes were sequenced using largescale phylogenetic profiling and revealed the evolutionary origin of two nodulation genes. These genes, nodI and nodJ (nodIJ), play key roles in the secretion of Nod factors, ...
