IMPROVING NITROGEN USE EFFICIENCY IN CROP PLANTS: ROLE OF THE AMMONIUM TRANSPORT FAMILY AMT

提高作物氮肥的利用效率将减少对环境有害的氮肥的使用，这些氮肥通过淋滤威胁到澳大利亚农业部门和当地水生态系统的可持续性。植物含有编码从土壤中吸收氮（铵和硝酸盐）所需的运输蛋白的基因。我们将确定铵转运蛋白AMT家族的植物活性以及控制植物铵的吸收和同化的相关信号通路。该项目将确认从土壤中吸收铵的机制，并导致开发氨氮高效作物。

Improving nitrogen use efficiency in crop plants will reduce the use of environmentally damaging nitrogen fertilisers that threaten through leaching the sustainability of Australia's agricultural sector and local water ecosystems. Plants contain genes that encode transport proteins required for the uptake of nitrogen (ammonium and nitrate) from the soil. We will identify the in planta activity of the AMT family of ammonium transporters and associated signalling pathways which control the uptake and assimilation of ammonium in plants. This project will confirm the mechanisms involved in ammonium uptake from the soil and lead to the development of ammonium-nitrogen efficient crop plants.
