Factors explaining differential retention of homoeologs in different TF families. a) Median expression level per TF family plotted against the percentage of the TF family in triads for TF families with >10 triads. The mean expression level of each gene in tpm was calculated using 15 tissues of Chinese Spring RNA-seq data and these gene-level values were used to calculate median expression level within the TF family. b) The percentage of tandem duplicated genes within each TF family plotted against the percentage of the TF family in triads for TF families with >10 triads. TFs were considered to be tandem duplicates when they were up to ±3 genes away from each other (i.e. up to two genes in between duplicates).
