Enrichment analysis of the DEGs between female and male trees. a Venn diagram showing the number of sex-related DEGs under UV-B radiation. b Enrichment analysis of the sex-related DEGs in several environmental stress-related GO terms. c The differential response of metabolic pathways between the female and male trees. Red color indicates the significance value P < 0.01. d Expression levels of phenylamine and tyrosine biosynthesis-related genes. e Expression levels of glutathione metabolism-related genes. f Expression levels of carotenoid biosynthesis-related genes. Red indicated up-regulated genes and green indicated down-regulated genes. The heatmap scale ranges from − 3 to + 3 on a log2 scale. g Analysis of the light-responsive cis-elements in upstream promoter sequences of differentially expressed TF genes. Different color boxes indicated various light-responsive cis-elements
