Agrifood production faces the dual challenges of an increasing world population and the threats of abiotic stresses arising from climate change and the erosion of arable land. Cereals, the major food crops, are poorly adapted to tolerate most abiotic stresses, including salinity. This project applies new technologies investigating spatial and temporal biochemical mechanisms a model cereal, Hordeum vulgare (barley), utilises to adapt and tolerate salinity. The aims are to investigate the role of specifically plasma membrane lipids modulating either signalling pathways or membrane fluidity that impacts on adaptation during salinity. The results will provide new leads for the development of cereal germplasm with increased salt tolerance.

农产品生产面临着世界人口不断增长以及气候变化和耕地侵蚀造成的非生物胁迫威胁的双重挑战。谷物作为主要粮食作物，很难适应大多数非生物胁迫，包括盐度。该项目应用新技术研究模型谷物大麦（大麦）用于适应和耐受盐度的空间和时间生化机制。目的是研究特定质膜脂质调节信号通路或膜流动性的作用，从而影响盐度适应。该研究结果将为耐盐谷类种质资源的开发提供新的线索。
