Extended Data Fig. 1: Sphagnum diversity panel genomic variation.
a) Sphagnum diversity panel chromosome variation. SNPs and INDELS are relative to the S. angustifolium reference genome. The minor allele frequency (MAF) < 0.05 and sites with > 20% missing data were excluded. Any variant within 25 basepairs of a repeat element was excluded. Figure shows variant counts within non-overlapping 100 Kb windows. b) Multidimensional scaling (MDS) plots for Sphagnum SNP variation, relative to the S. angustifolium reference genome. Principal coordinates (PCs) were calculated after subsetting SNPs based on linkage disequilibrium (LD-see methods for description). Each point are colored by subgenera and shaped by environmental niche preference. c) Unrooted maximum likelihood SNP phylogeny for the Sphagnum diversity panel. Branch color represents the subgenus, branch support values represent the ultrafast bootstrap values, and branch lengths represent the number of substitutions per site. Polyploid species are labeled with asterisks (***).
