Fig. 1: Genotypic and phenotypic variation with respect to population and genome structure within Pisum.
a, Taxa types and other classifications indicated by colour on the right, including wild taxa (P. fulvum, P. elatius and other wild taxa listed in Supplementary Tables 1 and 5) and domesticated taxa (P. abyssinicum and P. sativum), further divided into cultivars, landraces and other, which mostly comprises genetic stocks. The number in brackets denotes the number of accessions for each classification. b, Admixture analyses at K = 3 (average of 5 runs), K = 5 (average of 3 runs) and K = 8 (one run that splits K = 5 groups). Accessions strongly assigned to admixture groups are colour-coded, with grey indicating admixture (see Supplementary Table 5). c, Distribution of phenotypes for Mendel’s seven pea traits, with initials labelled as follows: R (round, pale) versus W (wrinkled, black), seed shape; Y (yellow) versus G (green), cotyledon colour; P (pigmented, purple) versus W (white, pale), flower colour; I (inflated, pale) versus C (constricted, black), pod shape; G (green) versus Y (yellow), pod colour; A (axial, pale) versus T (terminal, black), flower position; and T (tall) versus D (dwarf), internode length. The bar length is proportional to internode length. d, Principal component analysis (PCA) of PLINK distance matrix for all accessions, with accessions having Q value > 0.75 colour-coded. e, Splits Tree61 analysis of accessions with Q value > 0.75, with colours matching PCA groups. f, Pisum genomic variation map across all seven chromosomes, including SNPs, insertions and deletions (<50 bp), large-scale structural variations (SVs) and the linkage disequilibrium (LD)-based haplotype map.
