Maximum likelihood phylogenetic tree of SVP-like proteins from 10 Rosaceae species, five other eudicots and Amborella trichopoda. The tree was rooted using the single SVP-like sequence from the early diverging angiosperm A. trichopoda as an outgroup. The tree is drawn to scale, with branch lengths proportional to evolutionary distances between nodes. The scale bar indicates the estimated number of amino acid substitutions per site. Statistical support values on clades based on aLRT tests are represented as orange circles next to each node for those that resulted in posterior probabilities above 0.90, with diameters proportional to the actual value. The three main retrieved clades (SVP1, SVP2 and SVP3) are shown. Loquat SVP-like proteins are labelled with asterisks, and Arabidopsis AthSVP and AthAGL24 are highlighted. A schematic representation drawn to scale of conserved protein motifs detected using MEME is shown next to each sequence
