Influence of genetics and environment on grain quality.

Abstract
Wheat grain quality are strongly influenced by the effects of environment during grain fill. Environmental variables such as temperature, water and fertilizer influence the rate and duration of wheat grain development, protein accumulation and starch deposition in unique ways, and by different mechanisms. The effects of environment are superimposed on the intrinsic temporal patterns of gene expression during grain development. Integration of genomic and proteomic studies with developmental studies under controlled environmental conditions should make it possible to resolve complex patterns of gene expression during grain development, pinpoint key regulatory processes that are influenced by the environment, and reveal the Influence of genetics and environment on grain quality.
