Gene clustering of Huaxia 3 and Zhonghuang 24. (A and B) Genes are clustered based on scaled expression in Huaxia 3 and Zhonghuang 24. Expression, scaled gene expression. Mean, mean of gene expression (log values); DN, day and night. The black part of the bar indicates the supposed night in continuous light condition. (C) Intersection of gene clusters between Huaxia 3 and Zhonghuang 24. Width is scaled to cluster size of Zhonghuang 24. (D) Polymorphism count ratio of gene body and its flanking regions. Red shows genes that clustered consistently in Huaxia 3 and Zhonghuang 24. Green shows genes that clustered differently in Huaxia 3 and Zhonghuang 24. The polymorphism count of the genes with the same clustering groups were used as the control. U10K, U5K, U2K, and U1K are the upstream regions of 10, 5, 2 and 1 kilobases, respectively. D1K, D2K, D5K and D10K are the downstream regions of 1, 2, 5, and 10 kilobases, respectively. BODY, gene body
