Karrikins are a newly-discovered family of naturally-occurring plant growth regulators that stimulate seed germination and seedling vigour. They were discovered in smoke and while they are centrally important in fire ecology they have far wider significance since species from non-fire-prone regions also respond to karrikins. Our research will discover how karrikins work at the molecular level in plant cells. Our discoveries will be applied to improve growth of crop plants, to stimulate germination of weeds so that they can be eradicated, and in restoration ecology to revegetate degraded land such as minesites. Australia's world-leading position in this new important research area will be enhanced.

Karrikins是一个新发现的天然植物生长调节剂家族，可刺激种子萌发和幼苗活力。它们是在烟雾中发现的，虽然它们在火灾生态学中非常重要，但它们具有更广泛的意义，因为来自非火灾易发地区的物种也会对karrikins做出反应。我们的研究将发现karrikins如何在植物细胞的分子水平上发挥作用。我们的发现将被应用于改善作物的生长，刺激杂草的发芽，以便根除它们，并在恢复生态学中重新植被退化的土地，如矿区。澳大利亚在这一新的重要研究领域的世界领先地位将得到加强。
