This project aims to identify the molecular mechanisms responsible for the evolution of grasses using the C4 biochemical pathway that enables plants to survive in hot, dry, high-light environments. The endemic Australian subtribe Neurachninae is the only known grass group that contains C4 species, species using the ancestral C3 pathway, as well as species using pathways intermediate to C3 and C4. Through a comparative approach employing high-throughput sequencing technologies, it is expected that the molecular changes underlying the transition from C3 to C4 will be identified. These results should define what is required to engineer plant varieties with increased yield and the ability to withstand climate change effects.

该项目旨在确定负责使用C4生物化学途径的草进化的分子机制，使植物能够在炎热，干燥，高光环境中生存。澳大利亚特有的Neurachninae亚族是唯一已知的包含C4物种的草群，使用祖先C3途径的物种，以及使用C3和C4中间途径的物种。通过采用高通量测序技术的比较方法，预计将确定从C3到C4过渡的分子变化。这些结果应该确定需要什么来设计具有增加产量和承受气候变化影响的能力的植物品种。
