The production of staple crops such as wheat need to be increased by 50 % by 2050 to meet the global demand for food. However, water scarcity represents a major limiting factor for crop production and poses an increasing risk to global wheat production due to climate change. In recent years drought has affected wheat yields in the UK, contributing to 2020's harvest being the smallest for three decades. In this project interdisciplinary approaches will be used to identify new gene targets to improve drought tolerance and secure wheat yields for the future. The Research Group has recently discovered several transcription factors which delay senescence (ageing) in wheat, which they hypothesise could provide a route to improve drought tolerance, as has been shown in other plant species. A combination of genetic variation studies, knock-out mutants and overexpression lines will be used to ask whether these transcription factors can be used to improve drought tolerance.

到2050年，小麦等主要作物的产量需要增加50%，以满足全球对粮食的需求。然而，水资源短缺是作物生产的一个主要限制因素，并因气候变化而对全球小麦生产构成越来越大的风险。近年来，干旱影响了英国的小麦产量，导致2020年的收成为三十年来最少。在这个项目中，跨学科的方法将用于确定新的基因靶点，以提高耐旱性和确保未来的小麦产量。研究小组最近发现了几种延缓小麦衰老的转录因子，他们假设这可以提供一种提高耐旱性的途径，正如其他植物物种所显示的那样。结合遗传变异研究，敲除突变体和过表达系将被用来问这些转录因子是否可以用来提高耐旱性。
