FIG 4.

Nextclade phylogenetic tree from Fig. 3 magnified to visualize isolates with E484K mutations in clade 20B lineage P.2 (left) and isolates with the combined N501Y and E484K mutations, all of which belong to clade 20H/501Y.V2 lineage B.1.351 (right). Isolates from this study are denoted with asterisks. They are shown next to their nearest neighbors from the Nextstrain global reference tree, with branch length corresponding to nucleotide divergence. Isolates are colored by region in which they were collected. PANGO lineage names and Nextstrain clade names were assigned as of 5 April 2021.
