text: In M. truncatula , nodules develop to typically zoned indeterminate nodules (Vasse et al ., 1990 ), containing an apical meristematic zone I, a bacterial infection zone II, an interzone II–III where rhizobia have entered plant cells and begin to terminally differentiate involving cell elongation and genome amplification governed by plant nodule‐specific cysteine‐rich (NCR) peptides (Van de Velde et al ., 2010 ), a nitrogen‐fixing zone III, and a senescence zone IV that is formed only in older nodules.
