A new route to controlling root system architecture and drought tolerance.

该项目旨在改变我们对根构型与水和氮获取之间关系的理解，这些因素对产量至关重要。我们已经发现，受肽激素受体影响的突变体具有与获得水和氮相关的独特的根结构特征。突变体耐旱，根系对硝酸盐不敏感。该项目旨在确定受体的遗传输出，并期望发现改善水和硝酸盐获取的新方法，并确定我们的发现是否适用于作物。这些发现的应用将减少氮肥吸收不良造成的严重环境破坏，并提供可持续的方法来确保粮食安全。

This project aims to transform our understanding of the relationship between root architecture and water and nitrogen acquisition, factors critical to determining yield. We have discovered that mutants affected in a peptide hormone receptor have unique root architectural features relevant to acquiring water and nitrogen. The mutants are drought tolerant and their roots are nitrate insensitive. The project aims to define the receptor’s genetic outputs and expects to uncover new ways to improve water and nitrate acquisition and determine if our findings apply to crops. The application of these findings will reduce the severe environmental damage caused by poor nitrogen fertiliser uptake and provide sustainable ways to ensure food security.
