Supp_Fig1_Ubox_full_protein_maximum_likelihood_phylogram_linear.pdf

A multiple protein sequence alignment by MAFFT of 1121 U-box protein sequences from 21 species and four outgroup sequences containing a RING finger domain (A. thaliana RBX1, A. thaliana RMA1, S. cerevisiae RAD18, Homo sapiens TRAF6 ) was used to infer a phylogenetic tree by maximum likelihood with IQ-TREE. The implemented ultrafast bootstrap approximation, set to 2000 bootstrap samples, was used for branch support. The consensus tree was annotated using iTOL.

Supp_Fig2_Ubox_domain_maximum_likelihood_phylogram_linear.pdf

In order to analyse specifically the evolution of the U-box domain, the U-box domain of the final 1121 U-box protein sequences as well as the RING finger domain of the four outgroup sequences were isolated and aligned by MAFFT. The U-box domain alignment was then used to infer a phylogenetic tree by maximum likelihood with IQ-TREE. The implemented ultrafast bootstrap approximation, set to 2000 bootstrap samples, was used for branch support. The consensus tree was annotated using iTOL. This tree was used to interpret the evolutionary history of U-box proteins in the main text.
