|a Symbiosis between legumes and rhizobia results in the formation of nitrogen-fixing root nodules. Endoreduplication is essential for nodule development and efficient nitrogen fixation; however, the cellular mechanism by which rhizobial infection causes endoreduplication in symbiotic nodules and the roles of the resulting polyploid cells in nitrogen fixation remain largely unknown. Here, we developed a series of different approaches to separate infected cells (ICs) and uninfected cells (UCs) and determined their ploidy levels in soybean (Glycine max) developing nodules. We demonstrated that 4C nuclei exist in both UCs and ICs of developing nodules and that these 4C cells are primarily invaded by rhizobia and subsequently undergo endoreduplication. Furthermore, RNA-sequencing analysis of nuclei with different ploidy levels from soybean nodules at 12 d post-infection (dpi) and 20 dpi showed that 4C cells are predominantly ICs in 12-dpi nodules but UCs in 20-dpi nodules. We conclude that the infection of 4C cells by rhizobia is critical for initiating endoreduplication. These findings provide significant insight into rhizobial infection, nodule endoreduplication and nitrogen fixation in symbiotic nodules
