Plants form intimate relationships with soil microbes that give plants access to previously unavailable but essential nutrients. Legumes are major Australian crops for fodder, grain and nutrients, and are unique in forming symbioses with both nitrogen-fixing bacteria and with mycorrhizal fungi that supply nutrients such as phosphate. This project aims to determine the role of plant hormones (small, mobile, potent growth regulators) in the formation of these relationships. In particular, the role of interactions between hormones and other novel plant signals will be determined. An insight into the common and divergent roles of hormones in these symbioses is essential to provide new tools to maximise nutrient acquisition.

植物与土壤微生物形成了亲密的关系，使植物获得以前无法获得但必需的营养。豆类是澳大利亚主要的饲料、谷物和营养作物，在与固氮细菌和提供磷酸盐等营养物质的菌根真菌形成共生方面是独一无二的。该项目旨在确定植物激素（小的、可移动的、强效的生长调节剂）在这些关系形成中的作用。特别是，激素和其他新的植物信号之间的相互作用将被确定。深入了解激素在这些共生关系中的共同和不同作用对于提供新的工具以最大限度地获取营养至关重要。
