Maximum likelihood phylogenetic tree of 146 Pgt isolates based on 393,568 SNPs compared to the diploid Pgt21-0 reference assembly. Nodes are colored by the geographic region where isolates were collected. Node symbol indicates sequence data type: circle = whole genome sequencing, star = RNA-seq. Bootstrap values over 80% are shown as circles at branch midpoints. Scale is mean substitutions per site. Nuclear-phased references exist for isolates with bold names. Clade identifiers are based on previous reports using SNPchip analysis2,8,31.
