The root system is the first part of the plant to sense high concentrations of sodium and chloride ions in saline soils. The ability of roots to maintain growth in response to salinity is an important adaptation, increasing root soil exploration for nutrient and water uptake. The aim of this project is to identify the molecular mechanisms that control and regulate root growth in response to salinity using barley as a cereal model. The knowledge gained in barley will provide important information for increasing salinity tolerance in other Australian cereal crops, most notably wheat.

根系是植物的第一部分，在盐渍土中感受到高浓度的钠离子和氯离子。根保持生长以应对盐分的能力是一种重要的适应，增加了根对土壤养分和水分吸收的探索。该项目的目的是确定控制和调节根生长的分子机制，以大麦为谷物模型响应盐度。在大麦方面获得的知识将为提高澳大利亚其他谷类作物（特别是小麦）的耐盐性提供重要信息。
