This project aims to investigate new temperature-responsive factors that regulate cereal grain development to protect grain production under heat stress. The new research will leverage international collaborations with access to cutting-edge genetic and technological resources, and refine novel X-ray imaging techniques in Australia, to observe how temperature affects flower structure and function in barley and rice. Favourable mutations that optimise plant yield and fitness will be defined and explored in other, more complex, cereals such as wheat. Expected outcomes will be fundamental breakthroughs in understanding how plants respond to, and buffer, the effects of heat to lead to translational breeding strategies that bolster grain yield.

本项目旨在研究调节谷物发育的新的温度响应因子，以保护高温胁迫下的粮食生产。这项新的研究将利用获得尖端遗传和技术资源的国际合作，并在澳大利亚改进新的X射线成像技术，以观察温度如何影响大麦和水稻的花结构和功能。优化植物产量和适合度的有利突变将在小麦等其他更复杂的谷物中定义和探索。预期的结果将是在理解植物如何响应和缓冲高温影响方面的根本性突破，从而导致提高粮食产量的转译育种策略。
