Abstract:
Wheat one of the widely grown food crop, contributes around 27% of the world's grain production. Due to the lack of protein, and essential mineral nutrients in their diets, almost 40% of the global population are malnourished. Improving the nutritional value of wheat genotypes while maintaining high production is important. To address this issue, scientists, breeders, and the food industry employ a variety of strategies. Bio-fortification is a successful way to improve wheat's nutritional content. HD3298, a promising bio-fortified wheat genotype with high yield and high nutrient (Fe, Protein) content was developed recently. Two essential mineral elements required for plant growth and development are iron (Fe) and nitrogen (N). There seems to be relatively little understanding of the crosstalk between different nutrients and their effects in the shifting nutritional environment. In this study, we aimed to understand the effects of individual nutrient stress (-Fe, -N) and combination nutritional stress (-N-Fe) in hydroponically grown bread wheat. The information gained from the current study will be helpful for engineering plants' adaption to a fluctuating nutritional environment.
