Factors controlling ectomycorrhizal contributions to plant N nutrition

点击翻译按钮获取中文摘要

This project aims to define the mechanistic link between nitrogen metabolism in symbiotic ectomycorrhizal fungi and its effect on the quantity of nitrogen shared with a plant host. Using a genetically diverse population of a key Australian fungal species, the project expects to uncover genetic features related to nitrogen metabolism that correlate to improved support of plant nutrition. Expected outcomes include better understanding of plant-microbe interactions, groundwork for tools to better model the role of fungi in soil nutrient cycling and guidelines for plant:fungal pairings in reforestation practices. Overall, these should provide significant benefit to the global effort in understanding the role of soil microbes in plant nutrition.
