Phylogenetic evolutionary tree and gene structures of BRI1 gene family members. (A), an neighbor-joining (NJ) phylogenetic tree was constructed using the full-length protein sequence alignments of BRI1 genes identified using MUSCLE in MEGAX. Bootstrap supports were indicated by the colour of the branch. The OTUs are labelled as follows: Dicotyledons (blue); Monocotyledons (red); Amborella trichopoda (black). The colour blocks indicate the types, with type I (pink), type II (green), and type III (yellow) denoted. (B), Gene structures of the BRI or BRL genes. The lengths of rectangles and lines are scaled according to the mRNA lengths. CDSs (green rectangles), UTRs (yellow rectangles), and introns (black line) are denoted
