This project aims to investigate a recently discovered signalling system in plants that requires an unknown hormone to regulate seed germination and seedling growth. Burning vegetation produces karrikins that promote seed germination by signalling through a recently identified plant protein. Plants do not make karrikins and impairments to this protein results in increased seed dormancy and abnormal leaf growth, suggesting karrikins mimic an unknown plant hormone that regulates these aspects of plant development. The project aims to identify this phytohormone and elucidate its biosynthetic pathway. The identification of this new plant growth regulator would be a major advance for plant science and may create new opportunities in restoration ecology, weed control and food production.

该项目旨在调查植物中最近发现的信号系统，该信号系统需要一种未知的激素来调节种子发芽和幼苗生长。燃烧的植被会产生karrikins，通过通过最近确定的植物蛋白发出信号来促进种子发芽。植物不会使这种蛋白质的karrikins和损伤导致种子休眠和异常的叶片生长，这表明卡里金斯模仿了一种未知的植物激素，可调节植物发育的这些方面。该项目旨在鉴定这种植物激素并阐明其生物合成途径。对这种新植物生长调节剂的识别将是植物科学的重大进步，并可能在恢复生态，杂草控制和粮食生产方面创造新的机会。
