Attack by insects, molluscs and microbial pathogens causes significant losses to the oilseed rape crop and considerable expense is incurred in trying to counter this problem by using pesticides. The aim of this project is to undertake research to underpin the development of new oilseed rape varieties with increased resistance to insect herbivory. Exposure of plants to UV-B wavelengths, which are a natural component of sunlight, has been shown to reduce the attractiveness of plants to insect herbivores by altering plant chemical composition. Several plant responses to UV-B are mediated by a protein called UVR8 and the defence response to herbivory involves the regulatory molecule jasmonic acid. In this project, we will examine the potential of UVR8 and a protein called MYC2 that mediates the response to jasmonic acid to increase resistance to insect herbivory in oilseed rape. We will test whether transgenic over-expression of specific genes increases resistance to insect herbivory as 'proof of concept' that manipulation of the UV-B response could be used to develop new varieties.

昆虫、软体动物和微生物病原体的侵袭给油菜作物造成重大损失，并且试图通过使用杀虫剂来解决这个问题会产生相当大的费用。该项目的目的是进行研究，以支持开发具有增强的食草昆虫抗性的新油菜品种。研究表明，将植物暴露在 UV-B 波长（阳光的天然成分）下会改变植物的化学成分，从而降低植物对食草昆虫的吸引力。几种植物对 UV-B 的反应是由一种名为 UVR8 的蛋白质介导的，而对草食动物的防御反应涉及调节分子茉莉酸。在这个项目中，我们将研究 UVR8 和一种名为 MYC2 的蛋白质的潜力，该蛋白质可以介导对茉莉酸的反应，从而提高油菜对昆虫草食性的抵抗力。我们将测试特定基因的转基因过度表达是否会增加对食草昆虫的抗性，作为“概念证明”，即操纵 UV-B 响应可用于开发新品种。
