Analyses of single copy orthologs
We used OrthoFinder v.1.0.6 (Emms & Kelly, 2019) with a Diamond search
(Buchfink, Xie, & Huson, 2015) to identify orthologous groups of genes.
All single copy orthologs were aligned with MAFFT (Katoh & Standley,
2013), concatenated with FASconCAT-G (Kück & Longo, 2014), and their
relationships visualised with a neighbour net in SplitsTree.
