This project aims to transform our understanding of the regulation of meristem functions, with a central hypothesis that plant cell quiescence (repressed cell division) is governed by oxygen and oxidation/reduction (redox)-dependent cues. Meristems are the growing tips of plants, and thus the fundamental unit of plant growth and productivity. This project will develop new knowledge of how plants integrate changes in the environment to regulate meristem activity. This project will define new paradigms of how oxygen and redox status interact with energy and other cues to regulate decisions to grow or quiesce. This will underpin the development of new strategies to optimise crop management and productivity, improve the efficiency of inputs, and reduce the risk of decision making in crop production.

该项目旨在改变我们对分生组织功能调节的理解，其核心假设是植物细胞静止（抑制细胞分裂）受氧和氧化/还原（氧化还原）依赖性线索的支配。分生组织是植物生长的顶端，是植物生长和生产的基本单位。该项目将开发植物如何整合环境变化以调节分生组织活动的新知识。这个项目将定义氧气和氧化还原状态如何与能量和其他线索相互作用的新范式，以调节生长或静止的决定。这将支持制定新的战略，以优化作物管理和生产力，提高投入的效率，并降低作物生产决策的风险。
