The gamma-gliadin multigene family in common wheat (Triticum aestivum) and its closely related species.

ABSTRACT:

Background

The unique properties of wheat flour primarily depend on gluten, which is the most important source of protein for human being. gamma-Gliadins have been considered to be the most ancient of the wheat gluten family. The complex family structure of gamma-gliadins complicates the determination of their function. Moreover, gamma-gliadins contain several sets of celiac disease epitopes. However, no systematic research has been conducted yet.

Results

A total of 170 gamma-gliadin genes were isolated from common wheat and its closely related species, among which 138 sequences are putatively functional. The ORF lengths of these sequences range from 678 to 1089 bp, and the repetitive region is mainly responsible for the size heterogeneity of gamma-gliadins. The repeat motif
