Grain legumes are essential for sustainable agriculture and human dietary protein, but seed quality is predicted to decline under future scenarios of high CO2 and warmer temperatures. This project aims to improve legume seed quality under future climates by comparing metabolites and physiological traits of chickpea and other legumes to establish mechanisms by which legumes maximise seed nutrient allocation. The anticipated outcomes include new metabolite-based breeding markers for the improvement of crops with higher seed proteins, micronutrients and bioactive compounds that are adapted to future climates. Seed nutrient improvement will also include increased biological nitrogen fixation to reduce the need for chemical nitrogen fertilisers.

谷物豆类对于可持续农业和人类膳食蛋白质至关重要，但预计在未来高二氧化碳和气温升高的情况下，种子质量会下降。该项目旨在通过比较鹰嘴豆和其他豆类的代谢物和生理特征，建立豆类最大化种子营养分配的机制，提高未来气候下豆类种子的质量。预期成果包括基于代谢物的新育种标记，用于改良具有更高种子蛋白、微量营养素和生物活性化合物的作物，以适应未来的气候。种子营养改良还包括增加生物固氮，以减少对化学氮肥的需求。
