Figure 2

A schematic presentation of anther and pollen development in wild type (WT) rice, wild-abortive CMS (WA-CMS) rice, temperature- and photoperiod -sensitive genic male sterile (TGMS and PGMS) rice. Stage demarcation and developmental features of WT rice are adopted from Zhang and Wilson ([2009]); those of WA-CMS, TGMS and PGMS are according to Luo et al. ([2013]), Ku et al. ([2003]), and Ding et al. ([2012a]), respectively. Dots represent the DNA fragmentations detected by TUNNEL assay in tapetal cells undergoing programmed cell death. AP, aborted pollen; BP, binucleate pollen; E, epidermis; En, endothecium; ML, middle layer; T, tapetum; MMC, microspore mother cell; MC, meiotic cell; DY, dyad; Td: tetrad; MP, mature pollen.
