Protein and gene structure of grasses PMEs. (a) Schematic representation of WheatPME1 structure in Triticum aestivum cv. Chinese Spring as predicted by FGENESH (http://linux1.softberry.com). In color the different gene regions. I = intron sequence of 84 bp; Exon 1 = 1053 bp; Exon 2 = 555 bp. (b) Protein and gene structures of grasses PME sequences related to WheatPME1. Left: graphic representation of PMEs; in yellow is indicated the pro region and in green the PME domain. Numbers inside the blocks indicate the lenght of aminoacid sequences. Right: Syntenic relationships among the PME genes; the black block indicates the most conserved nucleotide stretch showing the same position and orientation in all the grasses domain. For each PME, the plant origin, accession number and % of aa identity with respect to WheatPME1 are indicated.
