Fig. 1. The four Castanea taxa show distinct genomic variation.

Fig. 1

a Map showing the distributions of samples collected. Each of the four taxa is shown in a different color. b Frequency polygon of DXY per base pair for each pair out of the four taxa, using a sliding-window approach with a window size of 100 kbp. Abbreviations are: s = C. seguinii, m = C. mollissima, h = C. henryi var. henryi, o = C. henryi var. omeiensis (the same below). c, d PCoA showing the first three coordinates and the percentage of variation explained by each coordinate. The four colors represent samples collected from the four taxa. e Population structure estimated by admixture analysis for all four Castanea taxa. f maxFST analysis of 100 kbp nonoverlapping windows across the 12 chromosomes between C. henryi var. henryi and C. henryi var. omeiensis. The 12 chromosomes are represented by different colors. g maxFST analysis of 100-kb nonoverlapping windows across the 12 chromosomes between C. mollissima and C. henryi var. omeiensis. The arrow in g indicates windows where fixed differences between C. henryi var. omeiensis and the two parental taxa (C. henryi var. henryi and C. mollissima) can be observed.
