Phylogenetic tree and gene structures of TaPRX-2A and related PRXs in wheat Ae. tauschii, and other plants. a The neighbor-joining tree elaborated in this study. Amino acid sequences of the PRX domain were used to construct the neighbor-joining tree using the MEGA-CC 7.0 software with the p-distance model. Most sequences belong to subfamily VI of class III PRX and some branches are compressed. Detailed information is showed in Additional file 4: Figure S1. b The exon–intron structures of some PRXs examined in this study. Red boxes represent the PRX domain; white boxes represent other exon regions; black boxes represent untranslated regions (UTRs); lines represent the PRX introns; numbers 0, 1, and 2 represent the exon phases. The long introns are shortened by “//.” Our investigated PRX (TraesCS2A02G573900.1.cds1) in T. aestivum is circled by a red or cyan box
