This project aims to develop nitrogen-fixing legumes adapted to the changing climate. Nitrogen fixation from legumes is worth $3 billion to the Australian agricultural economy, but changing rainfall patterns threaten much of this. One solution is to transition pasture growth to a reliance on perennial plants, which are less affected by unseasonal rain. Lebeckia ambigua is an outstanding perennial legume to begin this change, but its nitrogen fixation is compromised by nodulation failure caused by death of its symbiotic rhizobia. This project intends to improve the survival in acid and infertile soils of the unique rhizobial symbionts the research team has discovered for Lebeckia ambigua in South Africa.

该项目旨在开发适应气候变化的固氮豆科植物。豆类作物的固氮为澳大利亚农业经济带来了30亿美元的价值，但不断变化的降雨模式威胁到了其中的大部分。一种解决方案是将牧草的生长转变为依赖多年生植物，因为多年生植物受反常降雨的影响较小。多年生豆科植物多年生豆科植物多年生甜菜属植物，其固氮能力受到共生根瘤菌死亡导致的结瘤失败的影响。该项目旨在改善研究小组在南非发现的独特的根瘤菌共生体在酸性和贫瘠土壤中的存活率。
