Fig. 1From: Comparative transcriptome analysis and ChIP-sequencing reveals stage-specific gene expression and regulation profiles associated with pollen wall formation in Brassica rapaComparison of pollen grains of the sterile line ‘Bcajh97-01A’ (A line) and the fertile line ‘Bcajh97-01B’ (B line) of Brassica rapa. a, e Scanning electron micrographs of mature pollen grains. b, f Magnified images show details of the pollen morphology. c, g Pollen morphology under bright field microscopy. d, h Pollen grains stained with 4′, 6-diamidino-2-phenylindole (DAPI) solutionBack to article page
