CNS variation is associated with expression diversity between paralogous genes in maize. (A) Correlation of CNS similarity and expression similarity of paralogous gene pairs. Red dots indicate negatively correlated genes; blue dots indicate positively correlated genes across tissues. (B) The shared proportion of CNS sites for negatively (red) and positively (blue) correlated paralogous gene pairs. (C) The diversity of CNS maintained by the maize major copy and minor copy for negatively (red) and positively (blue) correlated gene pairs. (D) Correlation of expression levels of the maize major copy genes with their sorghum homologous genes (red) and minor copy genes with their sorghum homologous genes (green) in shoots for genes with negatively correlated expression patterns across maize tissues in panel A.
