    • Figure 1. 

      Phylogenetic and genetic structure analyses of cabbage varieties with different maturation times. (a) A neighbour-joining phylogenetic tree constructed using whole-genome SNPs data. The red lines represent early-maturing of cabbages; green lines represent late-maturing of cabbages; blue lines represent mid-maturing of cabbages. The clades clustered by each maturity resource were identified with corresponding colors. (b) Genetic structure plots with K = 2–4. The y axis quantifies the proportion of the individual's genome from inferred ancestral populations, and x axis shows the different individuals. The color of the sample code represents the same meaning as in (a).

    • Figure 2. 

      Genomic regions with selection sweep signals in different mature cabbages. (a) Distribution of ln ratio (θπ, early/middle) and FST. Green dots represent windows fulfilling the selected regions requirement in early-maturing cabbages; blue dots represent selected regions in mid-maturing. (b) Distribution of ln ratio (θπ, middle/late) and FST. Blue dots represent selected regions in mid-maturing; green dots represent selected regions in late-maturing. (c) Distribution of ln ratio (θπ, early/late) and FST. Blue dots represent selected regions in early-maturing; green dots represent selected regions in late-maturing.

    • Figure 3. 

      KEGG pathway enrichment of the candidate genes in different mature cabbages. Enrichment result of candidate genes located in the (a) early-maturing and (b) mid-maturing resources respectively in early-maturing vs mid-maturing analysis; (c) mid-maturing and (d) late-maturing resources respectively in mid-maturing vs late-maturing analysis; (e) early-maturing and (f) late-maturing resources respectively in early-maturing vs late-maturing analysis.

    • Figure 4. 

      GO annotation of the candidate genes in different mature cabbages. Annotation result of candidate genes located in the (a) early-maturing, and (b) mid-maturing resources respectively in early-maturing vs mid-maturing analysis. Result of candidate genes located in the (c) mid-maturing, and (d) late-maturing resources respectively in mid-maturing vs late-maturing analysis. Result of candidate genes located in the (e) early-maturing, and (f) late-maturing resources respectively in early-maturing vs late-maturing analysis.
