Fig. 1 — Maximum likelihood phylogenetic tree of catalytic PI3Ks subunits. The tree was inferred with the UL3+ Γ ₄ model (398 sites, 139 sequences). Sequences are colored according to their taxonomic classification. Green circles correspond to nodes with SH >0.95 and BS >80 %. Blue and yellow circles correspond to nodes having either SH >0.95 or BS >80 %. Duplication events are indicated by an orange “D”. The scale bar represents the average number of substitutions per site
