Fig. 6From: Mixed infection of ITPase-encoding potyvirid and secovirid in Mercurialis perennis: evidences for a convergent euphorbia-specific viral counterstrikeEvolution of the phytoviral ITPases based on an unrooted ML phylogenetic tree. The global tree was built for a curated alignments of representative ITPases using the substitution model LG + F + G4 + I in combination with 1000 bootstrap replicates. Branches with < 80% bootstrap support were collapsed. The tree scale is given in substitution per site. The phytoviral lineages are colored in redBack to article page
