Schematic view of the sporopollenin synthesis pathway in Arabidopsis and peach. Arabidopsis proteins involved in sporopollenin synthesis and deposition, and the transcriptional regulation of late anther development are shown in black. Peach putative orthologs of the genes coding for these proteins are shown in green (cluster A and non-clustered genes with earlier expression) and red (cluster B with later expression). Discontinuous arrows indicate transcriptional interactions. This figure has been adapted from .
