Clusters of differential expression TFs (DETFs). DETFs were clustered and displayed in line chart using Mev. Six clusters were grouped. X-axis represents the five different developmental stages of L. japonica flower including S1, S2, S3, S4 and S5. Y-axis represents normalized value of the DETFs’ expression level. The middle black line in each cluster is the zero line and the red line indicates the average expression level. The number in the upper left corner represents the number of TFs in each cluster
