NAC transcription factor expression during Gossypium hirsutum SCW and PCW formation. The heat map shows the RNA expression level as normalised FPKM of each differentially expressed NAC across the five tissues sampled. The differentially expressed NAC transcription factors were classified into ‘NAC TF groups’ based on phylogenetic similarity with Arabidopsis NACs (Additional file 7). XYLM, stem xylem; PITH, stem pith; SF07, seed fibre at 7 DPA; SF15, seed fibre at 14, 15, 16, DPA; SF25, seed fibre at 25 DPA; DPA, days post anthesis
