Fig. 8. — Model of the role of gibberellin (GA) and ethylene during nodule development in pea. The scheme shows infection and nodule development, including (A) root hair curling, (B) infection thread development, (C) initiation of cell division in the inner cortex (grey cells), (D, E) nodule organogenesis, including entry of bacteria (speckled cells), and (F) a mature nodule with cells containing enlarged nitrogen-fixing bacteroids (black cells). GA suppresses the action of DELLA proteins, and DELLA in turn promotes stage B and suppresses stages C–F. Ethylene acts through EIN2 to inhibit stages B and C. GA appears to act relatively independently of ethylene during stage B but can interact with ethylene at stage C.
