—The abundance and tissue expression patterns of pineapple TFs and TCs. The bar graph shows the total number of members (X-axis) identified for each TF/TC family (listed along Y-axis) in pineapple. The TFs and TCs in each family are further grouped and color coded based on their expression in the four tissues—flower, leaf, root, and fruit. N.D., not detected (FPKM 0 in all tissues); Low (FPKM <10 in all tissues), groups C1 to C6 are the largest clusters obtained by clustering the normalized FPKM values from four tissues (see fig. 2 for the major clusters).
