Figure 5From: Identification of diverse full-length endogenous betaretroviruses in megabats and microbatsA proposed series of events leading to the current diversity in the genus Betaretrovirus. The proposed series of evolutionary events leading to eight distinct sub-groups of betaretroviruses based on a combination of the phylogenetic analyses of Gag, Pol, and Env protein sequences, and the genomic features and organizations of individual betaretroviruses.Back to article page
