Molecular dissection of systemic regulation of nodulation in legumes

该项目旨在发现和描述控制豆类根瘤数量的关键新因素。豆科植物可以通过形成专门的根瘤来提高作物生产力和改善农业的可持续性，根瘤中含有固氮根瘤细菌。该项目将使用多学科方法来确定难以捉摸的枝条衍生抑制分子，并确定其在结瘤控制中与新基因、microRNAs和植物激素的相互作用。这些发现将极大地加强目前的结瘤模型，并将有利于开发新化合物和作物品种的战略，以减轻化肥需求、改善土壤条件和提高粮食安全。

This project aims to discover and characterise critical new factors that control legume nodule numbers. Legume plants can increase crop productivity and improve agricultural sustainability by forming specialised root nodules that house nitrogen-fixing rhizobia bacteria. The project will use a multidisciplinary approach to identify the elusive Shoot Derived Inhibitor molecule and define its interaction with novel genes, microRNAs and phytohormones in nodulation control. Findings will considerably enhance the current nodulation models and will benefit strategies to generate new compounds and crop varieties that mitigate fertiliser requirements, improve soil conditions and increase food security.
