Regulation of photosynthesis by phosphorus in Australia’s C3 and C4 tropical grasses

具有明显不同光合生物化学（C3和C4）的热带草主宰着澳大利亚广阔的热带草原。在这片古老的土地上，土壤中磷的含量长期偏低，而磷在调节光合作用中起着至关重要的作用。该项目将使用综合实验方法和代谢组学等新技术来揭示和定义磷调节C4草复杂光合生物化学的复杂机制。该项目产生的新科学知识将用于牧场管理模式，以确保实施成功的战略，减少我们脆弱草原的土壤流失。

Tropical grasses with distinctly different photosynthetic biochemistry (C3 and C4) dominate Australia's vast tropical grasslands. The soils of this ancient landscape are chronically low in the mineral nutrient phosphorus that plays a crucial role in regulating photosynthesis. The project will use an integrated experimental approach and novel techniques such as metabolomics to unravel and define the intricate mechanisms by which phosphorus regulates the complex photosynthetic biochemistry of C4 grasses. The new scientific knowledge generated by the project will be used for pasture management models to ensure that successful strategies are implemented to reduce soil loss from our fragile grasslands.
