This project aims to make a step-change in understanding how the growth of woody perennial crops is regulated. The study of herbaceous annual plants has established that the antioxidants, ascorbate and glutathione, are important in regulating every step of plant development. However, this cannot readily translate to perennial life cycles. This project will develop novel genetic tools in grapevine that enable functional studies of these antioxidants in a perennial plant for the first time. It will investigate how ascorbate and glutathione regulate the development of grapevine, and how these functions integrate with hormone and energy metabolism. The outcomes will advance our ability to manage perennial crops in current and future climates.

该项目旨在在理解如何调节多年生木本作物的生长方面做出重大改变。对一年生草本植物的研究表明，抗氧化剂、抗坏血酸和谷胱甘肽对于调节植物发育的每一步都很重要。然而，这不能轻易转化为多年生的生命周期。该项目将在葡萄树中开发新型遗传工具，首次能够对多年生植物中的这些抗氧化剂进行功能研究。它将研究抗坏血酸和谷胱甘肽如何调节葡萄树的发育，以及这些功能如何与激素和能量代谢相结合。研究结果将提高我们在当前和未来气候下管理多年生作物的能力。
