Figure 4From: Gene expression analyses in maize inbreds and hybrids with varying levels of heterosisRelationship between parental genetic diversity and differential gene expression. The number of differentially expressed genes identified for each inbred-hybrid group based on stringent statistical criteria is plotted against the genetic distance between parents. Spots representing crosses between stiff stalk (SS) and non-stiff stalk (NSS) groups are shown in red, and spots representing crosses within either group are shown in blue. The Pearson's R correlation value and p-value of the regression are shown.Back to article page
