Phylogenetic relationships of the odorant receptors (OR) and their expression profiles in M. destructor. A distance-corrected neighbor-joining tree (bootstrap consensus, topology only) based on M. destructor OR amino acid sequences and rooted by MdORCO. The tree was constructed using Mega 5 after multiple sequence alignment in ClustalX. Numbers on branches indicate bootstrap support (1000 iterations) and are only displayed if >70 and on major branches. Expression levels of the Or genes in the four transcriptomes are represented in a heat plot based on log-transformed FPKM values. Zero expression is represented by the lightest yellow color. Suffixes to gene names are explained in the Methods section.
