Developmental and environmental effects on the assembly of glutenin polymers and the impact on grain quality of wheat

► Wheat kernel development phases are cell division, cell enlargement and dehydration. ► Glutenin polymerization, a post-translational process occurs during dehydration phase. ► Glu-D1d allele starts to polymerize earlier than Glu-D1a allele. ► Glu-D1d allele is more tolerant to heat stress than Glu-D1a allele. ► Sulphur deficiency shifts molecular weight (MW) distribution to higher MW.
