Sporopollenin biosynthetic genes TaABCG15, TaCYP703A3, TaCYP704B2, TaDPW and TaPSK1, are expressed in anthers after TaMs1. qRT-PCR expression profile of TaABCG15, TaCYP703A3, TaCYP704B2, TaDPW and TaPSK1 in anthers containing pre-meiotic microspores to mature pollen, pistil, shoot, root, glume, lemma and palea. St1, Spike white anthers; St2, archesporial cells; St3, pre-meiotic pollen mother cells; St4, meiotic microspores; St5, early uninucleate; St6, late uninucleate; St7, binucleate; St8, mature pollen. Error bars reflect standard error of three independent tissue replicates (n = 3)
