Figure 3

Occurrence and absence of genes from different ancestral groups across the Aegilops/Triticum genomes. Overview of the occurrence of genes from the six groups recognised from the maximum likelihood trees (Figure 2, Additional file 4), represented here as Gr1-Gr6 to the left, in all taxa for which we have gamma-gliadin sequences, sorted by genome (at the top). Color in a cell means present, empty means absent. Text in cells indicates additional features: ‘pseudo’ means that all sequences represent pseudogenes (i.e., with stopcodons); ‘9 cys’ indicates that all genes contain exactly 9 cysteines (all other gamma-gliadins generally contain 8 cysteines).
