Figure 3From: Gene make-up: rapid and massive intron gains after horizontal transfer of a bacterial α-amylase gene to BasidiomycetesReconstitution of intron gain and loss events mapped on a species tree. Branch lengths are proportional to time, the time scale in million years is shown below. Numbers along the branches are intron positions. HGT: horizontal transfer event. Black numbers: intron gains; red numbers: intron losses in all gene copies in a clade; green numbers: intron loss in some, but not all gene copies in a clade; blue numbers: intron gains specific to Stehi1|78757|. Black crosses show complete gene losses.Back to article page
