TEM analysis of developing anthers in WT (A-I) and MT (a-i) plants. Cross-sections of WT and MT anthers at the tetrad stage (A, B and a, b), uninucleate pollen stage (C, D and c, d), binucleate pollen stage (E-H and e-h) and mature pollen stage (I and i) are shown. Anther wall is showed in B, C, I (WT) and b, c, i (MT). Pollen is showed in E, G (WT) and e, g (MT). Pollen wall is showed in D, F, H (WT) and d, f, h (MT). Ba, bacula; E, epidermis; En, endothecium; Ex, exine; In, intine; ML, middle layer; Ne, nexine; T, tapetum; Te, tectum; Tr, tryphine. Bar = 10 μm in (A-C, and a-c), 20 μm in (E, G, I, and e, g, i), 2 μm in (D, F, H, and d, f, h). The ellipses and arrows point out the major differences between WT and MT in the same development stages
