From: Genomic insights into positive selection during barley domestication
Comparisons of genomic features between PSGs and NSGs during the initial process of barley domestication. The line in the box is the median value, and the lines at the bottom and top of each box are the first (lower) and third (higher) quartiles. Violin plots represent the density of gene numbers. a-l The plots display of Ka, Ks, Ka/Ks, gene length, intron length, exon length, first exon length, exon number, GC content, CAI, CBI and Fop between PSGs and NSGs. Blue and purple boxes represent positively and negatively selected genes, respectively
