Tissue-specific expression pattern of NAC genes in 22 different tissues and development of two wild peanuts. The illumina RNA-seq data from Clevenger et al. [36] were reanalysed, the average FPKM values were log2 transformed and a heatmap was obtained using HemI. The expression intensity shows in different colours (red, high expression; green, low expression; black, no expression). The bar at the top represents 22 different tissues and developmental stages; NAC genes from A. duranensis and A. ipaensis are shown on the right
