Yield losses in crop plants due to increasingly saline soils are linked to the effects of salt on chloroplasts. By comparing chloroplast water- and salt-transport mechanisms of closely related salt-loving and salt-sensitive plants, this Fellowships aims to discover how chloroplasts maintain function in saline conditions. Novel biophysics and molecular techniques will be used to characterise transporters in model plants, and proof-of-concept complementation experiments aim to confer salt tolerance on sensitive plants. These fundamental insights are likely to lead to rapid, step-change improvements in salt tolerance, especially in agriculturally relevant crops, to benefit Australia’s agri-industry and ensure food security in the future.

盐碱化土壤造成的作物产量损失与盐对叶绿体的影响有关。通过比较亲缘关系密切的喜盐植物和盐敏感植物的叶绿体水盐运输机制，本研究旨在发现叶绿体在盐水条件下如何维持功能。新的生物物理学和分子技术将用于描述模式植物中的转运蛋白，概念验证互补实验旨在赋予敏感植物耐盐性。这些基本见解可能会导致耐盐性的快速、阶段性改善，特别是在农业相关作物方面，从而使澳大利亚的农业产业受益，并确保未来的粮食安全。
