This project aims to use and develop new chemical and microscopy-based tools to test whether the cell-type specific plant hormone changes induced by rhizobia in legumes can be triggered in non-legumes. Most crop plants rely on fossil fuel-derived nitrogen fertilisers, while legumes benefit from biologically-fixed nitrogen through a symbiosis with rhizobia bacteria that initiate nodules. It is not understood why non-legumes cannot form this symbiosis. This project aims to apply detailed knowledge of nodulation in model legumes to a phylogenetically diverse range of nodulating and non-nodulating plant species. This is expected to give new insight into the evolution of nodulation and advance the long held goal of extending nodulation to non-legumes.

该项目旨在使用和开发新的化学和显微镜为基础的工具，以测试是否可以在非豆科植物中触发豆科植物根瘤菌诱导的细胞类型特异性植物激素变化。大多数农作物依赖化石燃料来源的氮肥，而豆类则通过与根瘤菌共生而受益于生物固定的氮。人们不明白为什么非豆科植物不能形成这种共生关系。该项目旨在将模式豆科植物结瘤的详细知识应用于系统发育多样化的结瘤和非结瘤植物物种。预计这将使新的洞察力的演变，并推进长期持有的目标，扩大非豆类作物的种植。
