Salinity is an increasing burden on the Australian economy & environment, with >2 million ha of salt-affected land, at an annual cost to agriculture over $187 million. One solution is to exploit naturally salt-tolerant plants to increase productive agricultural land and restore salt-affected environments. To do this, we must increase basic knowledge of the diversity & distribution of salt-tolerance. This project is the first to use DNA sequences from thousands of species to understand the evolution of salt-tolerance in order to provide the foundation for the development of new crop varieties, selection of species that can be developed for bioremediation, and identification of traits that will be profitable targets for breeding programs.

盐度对澳大利亚的经济和环境造成越来越大的负担，超过200万公顷的土地受到盐的影响，每年农业成本超过1.87亿澳元。一种解决办法是利用天然耐盐植物来增加农业用地，恢复受盐影响的环境。要做到这一点，我们必须增加耐盐性的多样性和分布的基本知识。该项目是第一个使用来自数千个物种的DNA序列来了解耐盐性的进化，以便为开发新的作物品种，选择可用于生物修复的物种以及鉴定将成为育种计划的有利可图的目标的性状提供基础。
