RNA in situ hybridization of SlHB8 during anther development of wild-type tomato plant. Anthers at MI, Tds, MUM, BM and MP stages were cross-sectioned for hybridization with antisense (upper) and sense (lower) probes of SlHB8. Black and white arrows indicate positive and negative in situ hybridization signals for SlHB8 transcripts respectively. BM: binucleate microspore stage; MI: microspore mother cell stage; MP: mature pollen stage; MSP: microspore pollen; MUM: middle uninucleate microspore stage; PG: pollen grain; T: tapetum; Td: tetrad; Tds: tetrad stage. Bars = 50 μm.
