Evolutionary relationship of B. orellana.
a Phylogenetic analysis based on alignment of concatenated proteins encoded by sets of 13 single copy genes  from 28 plant species and one moss species. b Phylogenetic analysis based on alignment of concatenated enzymes of the carotenoid/MEP pathways in 29 plant species and one moss species. Numbers near the branch points represent the bootstrap value produced by 1000 replications. The trees are drawn to scale, with branch lengths proportional to the number of substitutions per site. Single-celled green alga Chlamydomonas reinhardtii was used as an outgroup. Protein sequences and plant species used are listed in Additional file 1: Table S9
