FIGURE 4.
Distribution of sex‐biased (|log2FoldChange| > 1, adjusted p value <.05) and nonbiased expression genes in catkins. (a) Female‐biased genes. (b) Male‐biased genes. (c) Sex‐biased genes. (d) Nonbiased genes. The percentages of female‐biased, male‐biased or nonbiased expression genes are shown for different fold change categories (|log2FoldChange|). Light blue bars show values >1, blue indicate values >2, dark blue indicates >3, and open bars are changes less than or equal to two‐fold. Pearson's Chi‐squared test was used to test for significance differences of sex‐based expression genes in different regions (*p < .05)
