Whole genome-resequencing analysis and identification of candidate genes associated with knob phenotype. A Principal component analysis among 3 different geese breeds. W, Sichuan White goose; L, Landes goose; S, Lion head goose. B Distribution of Fst and log2(θπ ratio (LD/Others)) values (indicated by green and blue colors, respectively) calculated in sliding 50-kb windows with 10-kb steps. The data pointed in red were genomic regions under strong selection. C PSGs were intersected with the DEGs in the knob skin and bone. PSGs, candidate genes under positive selection; DEGs, differentially expressed genes. D Heatmap of 12 crucial genes associated with selected genes and major pathways. LP, skin located on knob of Landes goose; SP, skin located on knob of Lion head goose; WP, skin located on knob of Sichuan White goose; LG, bone located in knob of Landes goose; SG, bone located in knob of Lion head goose; WG, bone located in knob of Sichuan White goose. E Genomic region with strong selective sweep signals on scaffold 258 of goose. The values of Fst and log2(θπ ratio) were plotted. The shade represented the position of DIO2 gene in this scaffold
