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.

该项目旨在研究调节谷物发育的新温度响应因子，以保护热胁迫下的谷物生产。这项新研究将利用国际合作获取尖端遗传和技术资源，并在澳大利亚完善新型 X 射线成像技术，以观察温度如何影响大麦和水稻的花朵结构和功能。将在小麦等其他更复杂的谷物中定义和探索优化植物产量和适应性的有利突变。预期成果将是在了解植物如何响应和缓冲热量影响方面取得根本性突破，从而制定提高谷物产量的转化育种策略。
