Zinc nutrition influences the protein composition of flour in bread wheat (Triticum aestivum L.)

Effect of foliar application of Cu, Zn, and Mn on yield and quality indicators of winter wheat grain

“…According to Zhang et al (2012b), foliar application of only 0.4% ZnSO4 7H2O increased Zn content in the grain by 58%; Peck et al (2008) recorded twice the concentration of that element in the grain. This was not confirmed in our study.…”

“…Extra fertilization with Zn and Mn increased the proportion of glutenin proteins by 15.5% and 8.4%, respectively, in the wheat grain. Similarly, Peck et al (2008) studied the applied micronutrients and found a clear effect of Zn fertilization on the decrease in the content of gliadins and glutenins. A possible mechanism of the effect of Zn and Mn on protein is the interaction with cysteine and methionine residues in protein and the formation of disulfide linkages during polymerization.…”

Evaluation of Different Levels of Potassium and Zinc Fertilizer on the Growth and Yield of Wheat

“…Application of Zn fertilizers not only improves nutritional quality but also contributes significantly to grain production in Zn deficient soils [5,13]. Hao et al [14] found that after applying Zn fertilizer, Zn absorption in wheat increased significantly and its concentration in wheat grains increased by 18.8%.…”

Zinc fertilization alters flour protein composition of winter wheat genotypes varying in gluten content

“…Zinc (Zn) plays an important role in the formation of protein and nitrogen assimilation process in grains of winter wheat (Li et al 2011); Zn nutrition can affect flour quality by influencing the proportion of monomeric gliadins vs. polymeric glutenins. However, the specific mechanisms were not clear (Peck et al 2008). …”
