Phylogenetic relationships among turnip 28 OPT proteins. The molecular phylogeny was constructed from a complete protein sequence alignment of OPTs from turnip using the neighbor-joining method with a bootstrapping analysis (1000 replicates). The numbers beside the branches indicate bootstrap values. The exon–intron structures of BrrOPTs were analyzed by the online tool Gene Structure Display Servers 2.0 and were shown in the middle panel. The conserved motifs were detected using the MEME online tool (http://meme.sdsc.edu/meme/intro.html) and SMART (http://smart.embl-heidelberg.de/) (Right panel).
