A Phylogenomic relationships of L. rhizohalophila isolates, and the outgroup species Letendraea helminthicola (CBS 884.85, Pleosporales, Ascomycota). The maximum likelihood (ML) tree was constructed using 1,241,238 SNPs. The tree groups (or subpopulations) are indicated by red, blue, and purple colors. B Principal component analysis (PCA) of 29 individual isolates identified three distinct groups. Individuals within the same population are marked using the same symbols. The first and second principal components account for 41.5% and 17.4% of the variation, respectively. C ADMIXTURE plots for increasing numbers of clusters (K is set from 2 to 4). Simulations were set at 1000 bootstraps with tenfold cross-validation. Each individual is represented by a thin vertical bar, which is partitioned into K-colored segments and represents the individual affiliation to each cluster.
