Fig. 2: Geographic distribution and phylogenetic tree of silkworm.

a Geographic distribution of 1082 silkworms. b Phylogenetic tree based on genome-wide SNPs of 1082 samples. The clades in the green circle represent the local strains from the middle and lower reaches of the Yellow River area. The same color of circles and lines in a and b represents the same silkworm cluster. CHN-I (purple), improved strains in China; JPN-I (light blue), improved strains in Japan; China-Local (blue), local strains in China; Europe-Local (orange), local strains in Europe; Japan-Local (yellow), local strains in Japan; Tropics-Local (red), local strains in the tropic region (Guangdong and Guangxi provinces of China, South Asia, and Southeast Asia); Wild (black), wild silkworm; Genetic stock (gray); Unknown-Local (light gray), local strains without geographic information.
