Fig. 4: Phylogenetic tree of the B.1.351 lineage from Kenyan samples and those sub-sampled globally.

The tree was constructed from 82 genomes - 27 from Kenya (12 from this study), and 55 sub-sampled genomes from around the world. The global sub-sample included 29 genomes sampled from the earliest reported beta variants. The tree is rooted against the Wuhan/WHO1/2019 and Wuhan/Hu-1/2019 reference genome (Genbank accession no. LR757998 and MN908947). The genomes from this study are shown in dark blue circular tips, while other Kenyan genomes are shown in light blue circular tips. Genomes from other parts of the globe are shown in yellow circular tips. South African genomes occurred in the basal parts of the tree, while majority of the Kenyan genomes were in the more derived parts of the tree.
