Fig. 3From: Putative type 1 thymidylate synthase and dihydrofolate reductase as signature genes of a novel bastille-like group of phages in the subfamily Spounavirinae Comparative phylogenetic analysis of major capsid proteins (a) and tail sheath proteins (b) of 61 Spounavirinae phages using MEGA v6 [27] and Muscle programs and the Maximum Likelihood (ML) method. Bootstrapping was set to 1000 and the unrooted tree was collapsed at a less than 50 % bootstrap value.
