However, OsWJUMK1, the rice putative ortholog of PtMPK20-1/20-2, was found to be expressed in both vegetative and reproductive organs [25] as are the poplar putative orthologs, with PtMPK20-1 expression dominating over PtMPK20-2. The PtMPK16-1/16-2 pair of paralogs is particularly interesting, since PtMPK16-1 is highly expressed in both male and female floral buds, whereas transcripts corresponding to PtMPK16-2 are barely detectable in these organs. Taken together with the PtMPK3-1/3-2 patterns, this points to particularly rapid divergence of functional specificity that highly similar paralogous genes appear to have evolved within the context of reproductive organ development in poplar.","tracks":[]}
