Reverse transcriptase maximum likelihood tree. Following Zimmerly et al. [29], the tree was divided into three regions: mitochondrial lineage, bacterial groups and chloroplast-like lineage. Solid circles indicate branches with high support values (ML BP ≥ 95 and Bayesian PP = 1.0); grey circles indicate branches with moderate support values (95 > ML BP ≥ 75 and Bayesian PP ≥ 0.90). Branches with a ML bootstrap value below 50 % were collapsed
