Food security represents a major global issue. Significant improvements in crop yields are urgently required to meet the increase in world population by 2050. The ability of a crop to efficiently absorb water and nutrients from soil is dependent on its root system responding to the availability of these resources. For example, roots preferentially form branches when in contact with water employing a mechanism called hydropatterning. Understanding the regulation of root branching is of vital agronomic importance.This research project will investigate how hydropatterning works to position new root branches in response to water availability. Our research project attempts to 'fill in the gaps' between roots sensing water availability and then branching. To help our studies, we have already identified plant signals and genes such as auxin and ARF7 that are important for this process. Several promising processes will also be characterised including one that modifies ARF7 that switches on root branching. The knowledge gained from this study will provide new information about the key genes and processes controlling root branching in response to water availability, helping scientists design novel approaches to manipulate root architecture to enhance resource capture and yield in crops.

粮食安全是一个主要的全球问题。到2050年，迫切需要迫切需要提高农作物的产量。例如，与使用称为HydroPatterning机制的水接触时，根部优先形成分支。了解根分支的调节至关重要。该研究项目将研究水上原反映方式如何将新的根分支定位为响应水的可用性。我们的研究项目试图“填补根部感知水的供应和分支之间的差距”。为了帮助我们的研究，我们已经确定了对此过程很重要的植物信号和基因，例如生长素和ARF7。还将表征几个有希望的过程，其中包括修改ARF7的arf7。从这项研究中获得的知识将提供有关响应水的可用性控制根分支的关键基因和过程的新信息，从而帮助科学家设计了操纵根建筑的新方法，以增强农作物的资源捕获和产量。
