This project aims to develop an interdisciplinary research alliance to enhance the efficiency of ecological restoration for recalcitrant Australian rainforest plant species. The project expects to provide fundamental knowledge to target two major impediments to cryostorage of recalcitrant-seeded native species: desiccation sensitivity with relatively large size, and active metabolism and precocious germination. These attributes severely limit the time available for effective use of collected germplasm for long-term storage. A combination of biochemical, biophysical and molecular simulation approaches will be used to optimise cryopreservation of a wide range of endangered Australian rainforest species. This should provide significant benefits such as enabling conservation agencies to greatly enhance their ability to preserve the unique Australian rainforest flora, particularly given current threats due to habitat loss and global warming.

该项目旨在发展一个跨学科的研究联盟，以提高澳大利亚热带雨林植物物种的生态恢复效率。该项目预计将提供基础知识，以针对两个主要的障碍，以冷冻保存的柑橘种子的本地物种：干燥敏感性与相对较大的尺寸，和活跃的代谢和早熟发芽。这些属性严重限制了有效利用收集的种质进行长期储存的时间。生物化学，生物物理和分子模拟方法的组合将用于优化各种濒危澳大利亚雨林物种的冷冻保存。这应该会带来巨大的好处，例如使保护机构能够大大提高他们保护独特的澳大利亚雨林植物群的能力，特别是考虑到目前由于栖息地丧失和全球变暖造成的威胁。
