Figure 5

Development of nitrogen-fixing nodules (black arrows) on (a) nfr1-1snf1 and (b) nfr5-2snf1 double mutants inoculated with M. loti. Inset: Close-up of infected nfr1-1snf1 nodules. White arrow marks uninfected nodule. (c, d) Partially infected spotted nodules on (c) nfr1-1snf1 infected by nodA and (d) nfr1-1nfr5-2snf1 infected by nodC. (e) Thin section of nfr1-1snf1 nodA nodule shown in (c), r: root, i: infected cell. (f) Thin section of nfr1-1nfr5-2 snf1 nodule infected by nodC. Double arrowhead: intercellular bacteria, i: infected cell, arrow: newly divided infected cell. (g) Higher magnification of a nodC-infected cell in an nfr1-1nfr5-2 snf1nodule. Arrow: newly divided infected cell. Size bars (a, b): 1 cm, (c): 20 mm, (d): 500 μm (e) and (f): 100 μm, (g): 10 μm.
