  • Shown are the different classes within each gene family and the number of genes total, the number of syntenic genes, the number of nonsyntenic genes, and the number of transposed genes for each class for which there was available data. In B3 genes, REM-type genes disproportionately transpose (Swaminathan et al., 2008); for ATCHX genes, all transposed genes are associated with strong pollen expression. Most syntenic genes are associated with leaf and root expression (Sze et al., 2004).
