Phylogenetic relationship, gene structure and protein motifs distribuation of PtrINV family members in P. trifoliata. A The phylogenetic tree was constructed by MEGAX using the neighbor-joining algorithm and bootstraps with 1000 replicates for poisson correction model. The scale bar indicates to the relative amount of change along the branches, and numbers beside the branches of dendrogram represent bootstrap values. B Gene structure was built using the Gene Structure Display Server (GSDS). Brown rectangles refer to the exons, lines indicate to the introns, and blue rectangles show the upstream and downstream untransalated regions (UTR). C The distribution of protein conserved motif. D The sequence of motif
