Thiol-based redox sensing regulates the yellow pigment and antioxidant accumulation and improves the nutritional quality of wheat grains (<i>Triticum aestivum</i> L.).

ABSTRACT: Thiol-based redox sensing has been found to play diverse roles in regulating various metabolic pathways. Here, the thiol-based redox system of 16 diverse genotypes of wheat grains was characterized, and it correlated with the accumulation of macro-/micronutrients inside the grains. We observed significant variations in the thiol and disulfide content in the grains. An expression analysis of the genes responsible for thiol-based redox sensing, such as thioredoxin (TRX), glutaredoxin (GRX) and glutathione reductase (GR), showed maximum fold expression in wheat cvs. Halna and HD2985 (high thiol cvs.) during the seed hardening stage (G₂) of endosperm, as compared to low thiol-containing cvs. We retrieved the amino acid sequences of 11 genes
