Gene expression heatmap of candidate differentially expressed genes associated with cell division, cell expansion, and flowers in Aquilegia rockii. Red color boxes represent high gene expression, white and blue boxes represent relatively low expression. The orange line represents cell division-related genes; green and purple lines represent genes associated with cell expansion and flowers. AS1-3, cDNA from three independent biological samples of short-spurred flowers; AL1-3, cDNA from three independent biological samples of long-spurred flowers.
