Dormancy is an important economic and ecological trait of many trees and crop plants, including most commercially valuable fruit species. This project aims to: define oxygen and radicals of oxygen as central cues of grapevine bud development and dormancy; identify and model the developmental processes that occur during dormancy onset, maintenance and release (bud burst); as well as to identify the molecular and biochemical regulators of oxygen signals in bud dormancy. The knowledge generated could provide a platform to test impacts of climate change on fruit and tree species, and lead to better management of fruit and tree species in agricultural and ecological systems.

休眠是许多树木和农作物的重要经济和生态特性，包括大多数有商业价值的果树。该项目的目标是：将氧和氧自由基定义为葡萄芽发育和休眠的中心线索；识别和模拟休眠开始、维持和释放(芽爆发)期间发生的发育过程；以及识别芽休眠中氧信号的分子和生化调节因素。所产生的知识可以为测试气候变化对水果和树木物种的影响提供一个平台，并导致在农业和生态系统中更好地管理水果和树木物种。
