Longitudinal section of root nodules

Longitudinal section of root nodules showing zones of nodule development (own picture, 40-fold enlarged). Rhizobia grow in the meristem and mature on the way into the bright, main N2-fixing zone. When the rhizobia get inefficient, they olden and transfer the organic N to the plant (according to HIRSCH, A.M., (1992). New Phytol, 122, 211-237. In: SCHOPFER, P.; BRENNICKE, A., (2010). Pflanzenphysiologie. Springer. 621-627).
