Comparison of the pollen mother cell transcriptome with anther stages. (a) Venn diagram showing the expression of pollen mother cell (PMC) preferential genes identified by Tang and co-workers [45] in PMA, MA and SAM. The number of probe-sets expressed in each stage is indicated, with the number of genes specifically expressed in anthers indicated in parentheses. (b) A heat-map representing the expression profiles of 702 PMC preferential genes (from the original 917 identified in comparing the 44K and 57K chip - see reference [45]and the discussion) that are expressed in SAM and the four stages of anther development (PMA, MA, SCP and TPA).
