This project aims to determine how halophytes balance photosynthesis and water loss under extreme soil conditions. Salinity and drought affect crop production. Plants’ ability to balance carbon dioxide uptake and water loss through stomata determines how they cope with stressors. Halophytes can achieve this balance at conditions that normally kill 99% of crops, but how they do so is unknown. This project will characterise the transport systems mediating stomata function in halophytes and contribute to understanding the molecular and physiological basis of their operation. This should allow breeders to use this trait to improve crop performance under conditions of extreme salinity and drought.

该项目旨在确定盐生植物在极端土壤条件下如何平衡光合作用和水分损失。盐碱和干旱会影响作物产量。植物通过气孔平衡二氧化碳吸收和水分损失的能力决定了它们如何应对压力源。盐生植物可以在通常杀死99%的作物的条件下实现这种平衡，但它们如何做到这一点尚不清楚。这个项目将描述调节盐生植物气孔功能的运输系统，并有助于理解它们运行的分子和生理基础。这应该允许育种者利用这种特性来改善作物在极端盐分和干旱条件下的表现。
