Investigation of the metabolism, molecular targets and environmental fate of the seed germination stimulant, butenolide

丁烯内酯是一种强效催芽剂，有望为农业、土地恢复和恢复中使用的许多植物物种的种子萌发和幼苗活力提供实质性的好处。目前，对丁烯内酯在自然环境中的稳定性、持久性和分布以及种子休眠打破的机制了解甚少。这项研究现在为澳大利亚的研究提供了一个独特的机会，使其在了解调节种子休眠的过程，特别是与采矿后土地恢复有关的过程方面建立世界领先地位。研究结果将在植物保护、杂草控制和作物生产等方面有更广泛的应用。

The potent germination stimulant, known as butenolide, is expected to provide substantial benefits for improving seed germination and seedling vigour of many plant species used in agriculture, land restoration and rehabilitation. Currently, little is known about the stability, persistence and distribution of the butenolide in natural environments and the mechanism of seed dormancy breaking. This study now provides a unique opportunity for Australian research to establish a world-leading position in understanding the processes that regulate seed dormancy, particularly in relation to post-mining land rehabilitation. The research findings will also have wider application in plant conservation, weed control and crop production.
