A to C, Relative gene expression of the 14 pollen-specific PMEs in wild-type dry pollen grains (A), 1-h imbibed pollen grains (B), and 6-h-old pollen tubes (C) measured using stably expressed reference genes (At3g28750, At3g57690, and At5g59370) in three biological samples with similar results. Only the results obtained with At3g28750 are shown. The locus and the corresponding UniProt name of each protein are indicated. The data correspond to means ± sd of three technical replicates of a biological sample. D to F, Analyses of the expression of the promoter of PME48 using the pPME48::YFP construct by confocal microscopy in dry pollen grains (D), 1-h imbibed pollen grains (E), and during pollen tube growth (F). Images shown are overlays of the bright-field and fluorescent images. G to I, Analyses of the expression of the promoter of PME48 using the pPME48::GUS construct in dry pollen grains (G), 3-h-old pollen tube (H), anthers (I), and self-pollinated pistil (inset in I). a, Anther; ov, ovary; ovu, ovule; pt, pollen tube; s, stigma; st, style; tt, transmitting tract.
