The evolution of specialised orchid pollination and its reversibility. This project aims to determine the changes in key floral volatile compounds underpinning pollination transitions, identify their molecular basis, and understand the ecological processes favouring reversals away from extreme specialisation. By focusing on pollination of sexually deceptive Australian orchids, this project would be the first to determine the molecular, chemical and behavioural basis of evolutionary reversals to more generalised strategies in a group of plants facing high risk of pollinator extinction. The expected outcome, a mechanistic understanding of how pollination transitions occur, would be internationally ground-breaking, and provide crucial insights to protect this diverse but highly threatened group of plants.

兰花传粉的进化及其可逆性。该项目旨在确定支撑授粉转变的关键植物挥发性化合物的变化，确定其分子基础，并了解有利于从极端专业化逆转的生态过程。通过专注于有性欺骗的澳大利亚兰花的授粉，该项目将首次确定一组面临传粉者灭绝高风险的植物的进化逆转的分子，化学和行为基础。预期的结果是对传粉过渡如何发生的机制理解，这将在国际上具有开创性，并为保护这种多样化但受到高度威胁的植物群体提供重要见解。
