Mineral nutrients spatiotemporally participate in the biosynthesis and accumulation of storage biopolymers, which directly determines the harvested grain yield and quality. Optimizing fertilizer nutrient availability improves the grain yield, but quality aspects are often underestimated. We hypothesize that extensive mineral nutrients have significant effects on the biosynthesis, content, and composition of storage proteins, ultimately determining physicochemical properties and food quality, particularly in the context of climate change. To investigate this, we hierarchized 16 plant mineral nutrients and developed a novel climate-nutrient-crop model to address the fundamental question of the roles of protein and starch in grain-based food quality. Finally, we recommend increasing the added value of mineral nutrients as a socioeconomic strategy to enhance agro-food profitability, promote environmental sustainability, and improve climate resilience.
矿质营养在时空上参与贮藏生物聚合物的生物合成和积累，这直接决定了收获的谷物产量和品质。优化肥料养分的有效性可以提高谷物产量，但往往会低估质量方面。我们假设，大量的矿质营养对贮藏蛋白的生物合成、含量和组成有显著影响，最终决定了物理化学性质和食品质量，特别是在气候变化的背景下。为了研究这一点，我们对 16 种植物矿质营养进行了层次划分，并开发了一种新的气候-营养-作物模型，以解决蛋白质和淀粉在谷物食品质量中的作用这一基本问题。最后，我们建议增加矿质营养的附加值，作为提高农业食品盈利能力、促进环境可持续性和提高气候弹性的社会经济策略。
