Unveiling the gene-expression profile of pollen

José António da Costa-Nunes et al. Genome Biol. 2003.

Abstract

Four recent papers have characterized the transcription profile of pollen grains, showing striking differences between gene expression in pollen and other plant tissues. These studies increase the number of known pollen-expressed genes by as much as 50-fold and have identified many novel genes that are potentially pollen-specific.

Pollen-grain development. (a) A schematic representation of the stages of pollen development. (b) Arabidopsis pollen grains (Columbia accession), stained with DAPI to show DNA, at the stages indicated in (a). The larger uncondensed vegetative-cell nucleus (VCN; diffuse staining) and the condensed nuclei of one generative cell and two sperm cells (brighter dots in (b); GCN, generative-cell nucleus and SCN, sperm-cell nucleus) can be seen in the bicellular and tricellular pollen grains, respectively. The scale bar represents 10 μm. Adapted from [4,5].
