Transverse sections showing anther development in wild-type and sa1 plants. Transverse sections of wild-type anthers are shown in a-g, and those of sa1 anthers are shown in h-n. (a) and (h), premeiosis stage. (b) and (i), meiocyte stage. (c) and (j), tetrad stage. (d) and (k), early uninucleate stage. (e) and (l), late uninucleate stage. (f) and (m), binucleate stage. (g) and (n), mature pollen grain stage

DMsp, degenerated microspores; E, epidermis; En, endothecium; ML, middle layer; MMC, microspore mother cell; Mp, mature pollen; Ms., meiospores; Msp, microspore; T, tapetum; Tds, tetrads. Bars = 50 μm
