Characterization of the PM19 gene family. a Gene models of the PM19 genes in the QTL region, PM19-A1 and PM19-A2, showing in black the coding regions. Grey boxes in the promoters indicate the position of ABA-related motifs (ABRE and CE3 elements). Deletions and insertions between the two haplotypes identified for each gene are indicated above the genes by black bars or by a triangle, respectively. b Schematic representation of the homeologous supercontigs containing the PM19 genes. The arrows indicate the position of the genes. The PM19 genes are highlighted in black. c Phylogenetic tree of the PM19 gene family in wheat. The sequence of the Arabidopsis orthologue gene AtPM19-like was use as outlier. Numbers indicate the bootstrap support
