text: Indeterminate nodules display five developmental zones: meristem (Zone I), infection and differentiation (Zone II), transition region between Zone II and Zone III in which bacteria are engulfed by plant cells (interzone II–III), nitrogen fixation (Zone III), and senescence (Zone IV) (Vasse et al., 1990).
