Fig. 4From: Comparative analysis of basic helix–loop–helix gene family among Brassica oleracea, Brassica rapa, and Brassica napusKs value distribution of orthologous bHLH genes between A. thaliana and B. oleracea (a), A. thaliana and B. rapa (b), and A. thaliana and B. napus (c). The vertical axis indicates the frequency of paired sequences. The peaks of Ks value appeared between 0.3 and 0.4Back to article page
