a. Neighbor joining phylogenetic tree (inferred using the Jukes-Cantor nucleotide substitution model) of representative SCStV isolates together with a representative selection of mastrevirus genomes. Numbers associated with branches indicate the percentage of 1000 bootstrap replicates that support the existence of these branches. Branches with <60% bootstrap support have been collapsed. Maximum likelihood phylogenetic trees of the inferred CP (b) and Rep (c) amino acid sequences of the same genomes as in A inferred using LG + G + I substitution model (selected as the best fit using ProtTest [23]. Numbers associated with branches indicate the percentage probability that the branches exist according to an approximate likelihood ratio test (aLRT) of branch support. Branches with <80% aLRT support have been collapsed. The CP and Rep phylogenetic trees were rooted with the CP and Rep sequences of beet curtly top virus (BCTIV), a member of the genus Becurtovirus of the family Geminiviridae
