A signalling pathway for future crop improvement

该项目旨在破译控制植物气体交换的机制——释放氧气、失去水分、吸收二氧化碳的过程，对植物生长、食物、纤维和燃料生产至关重要。当植物遇到干旱、高温或洪水等压力条件时，它们会调整自己的生理机能，以保持生存能力并重新建立生长。该项目将通过提高作物对低水分和高温等与澳大利亚气候变化有关的条件的耐受性，操纵应激诱导的γ -氨基丁酸控制植物气体交换的能力，以帮助确保未来的粮食生产。

This project aims to decipher a mechanism that controls plant gas exchange – the process that emits oxygen, loses water, absorbs carbon dioxide and is essential for plant growth for food, fibre and fuel production. When plants encounter stressful conditions such as drought, high temperatures or flooding, they adapt their physiology to maintain viability and re-establish growth. This project will manipulate stress-induced gamma-aminobutyric acid’s capacity to control plant gas exchange to help secure future food production, through improving crop tolerance to stresses such as low water availability and high temperatures – conditions associated with a changing Australian climate.
