Fig. 8 in Nutritional restriction triggers callose accumulation on the sieve plates of the funiculus of developing bean seeds

Fig. 8. Scanning electron microscopy images of the funiculus sieve plates. Sieve plates in the funiculus of normally (N) developed seeds of 23 (A) and 25 DAA (D), seeds that continued (L, panels B and E), and seeds that stopped their development (S, panels C and F) after the fruits had been detached from the plant for 3 and 5 days, respectively. Arrows indicate the progressive reduction in the pore size in the funiculus of seed that no longer developed in detached fruits. Bar = 0.5 μm.
