TaAAP6-3B, a regulator of grain protein content selected during wheat improvement.

ABSTRACT:

Background

The content of grain protein (GPC) in cereals is an important part of total protein in human food. Exploring and utilizing new GPC genes is one of the most effective approaches for wheat quality breeding.

Results

Three homoeologues of TaAAP6(-3A, 3B, 3D)were cloned by homology cloning from OsAAP6.Temporal and spatial expression analysis showed that TaAAP6homoeologues were preferentially expressed in developing grains, and TaAAP6-3B may play a major role in regulating GPC in wheat. Association analysis indicated thatTaAAP6-3B-I is significantly correlated with higher GPC than that of TaAAP6-3B-II for 115 wheat lines in all five environments. TaAAP6-3B-I, the favored allele of TaAAP6-3B, was preferentially expressed in preliminary developing grain stage. Two functio
