Supplementary Figure 4: Comparison of TIR copy number in B73 and W22.
From: The maize W22 genome provides a foundation for functional genomics and transposon biology
a, The proportion of TIR families in each of the superfamilies (Activator (DTA); CACTA (DTC), PIF/Harbinger (DTH), Mutator (DTM), Tourist (DTT)) was determined for all TIR families (blue) in the B73 and W22 genomes. The proportion of TIR families in these categories was then determined for B73-specific (orange) and W22-specific (gray) families. b, The copy number in each TIR TE family is shown for B73 and W22. Color indicates superfamilies. c, The relative copy number for each LTR TE family in B73 and W22 is shown. In d, only families with <500 copies are shown. e, Boxplot of the percent identity of LTR sequences for LTR retrotransposons, demonstrating that elements in B73-specific families with at least five members (orange) are younger than members of shared families (blue) and elements in B73-specific families with fewer than five members (red). Line, median; box limits, first and third quartiles; whiskers, furthest point within 1.5 * IQR; points, outliers.
