Chromosomal mapping and frequency distribution of the PpNAC transcription factors. a, Physical locations of the putative PpNAC genes on each chromosome. Red, green, blue, orange, black and purple indicate groups 1, 2, 3, 4, 5 and 6 respectively. The chromosomal length is shown at the end while the chromosome number (Chr01-Chr17) is shining at the top. PpNAC genes located on scaffold are mapped on Cun1 and Cun2 with 10 Mb lengths. b, Number of PpNAC genes according to their frequency distributions on each chromosome. Each color shows different chromosome numbers
