Figure 4From: Classification and evolutionary history of the single-strand annealing proteins, RecT, Redβ, ERF and RAD52Maximum likelihood tree for the ERF superfamily of proteins. The designations, gene names and species abbreviations are as in Fig. 2A. The internal branches with RELL bootstrap support >70% are indicated by blue circles. The gene neighborhoods of the ERF proteins are shown whenever they contained gene coding for proteins with potential functional relevance. Gene abbreviations are as in Fig. 1BBack to article page
