Phylogenetic tree of the auxin receptors. (A) ABP1 class of receptors, (B) TIR1/AFB class of receptors. Maximum alignable protein sequences of the auxin receptors from apple (green), strawberry (lilac), Arabidopsis (black) and tomato (red) were aligned using MUSCLE and phylogenetic trees were built using neighbour joining. Bootstraps of 1000 iterations are given. At: Arabidopsis thaliana, Fv: Fragaria vesca, Md: Malus x domestica, Pp: Physcomitrella patens, Sl: Solanum lycopersicum
