Fig. 4From: Horizontal gene transfer and recombination analysis of SARS-CoV-2 genes helps discover its close relatives and shed light on its originPutative horizontal gene transfer events found for the RB domain (amino acid sequences) of 46 betacoronavirus organisms (extended version of Fig. 3i). Left part of the figure presents the gene tree of the RB domain. Right part of the figure presents the species tree (i.e. whole genome tree) with putative horizontal gene transfers mapped into it. The explanations of the caption of Fig. 3 also apply for this figureBack to article page
