Ascorbate and glutathione integrate the control of grapevine development

该项目旨在改变人们对木本多年生作物生长调控方式的理解。对一年生草本植物的研究证实，抗氧化剂抗坏血酸和谷胱甘肽在调节植物发育的每一步都很重要。然而，这不能轻易转化为长期的生命周期。该项目将在葡萄上开发新的遗传工具，首次在多年生植物中研究这些抗氧化剂的功能。它将研究抗坏血酸和谷胱甘肽如何调节葡萄的发育，以及这些功能如何与激素和能量代谢相结合。这些成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。

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.
