Factors controlling ectomycorrhizal contributions to plant N nutrition

本计画的目的是探讨外生菌根共生菌的氮代谢与其对植物宿主氮素分享量的影响。该项目利用澳大利亚一种关键真菌物种的遗传多样性种群，预计将揭示与氮代谢相关的遗传特征，这些特征与改善植物营养相关。预期成果包括更好地了解植物-微生物相互作用，为更好地模拟真菌在土壤养分循环中的作用的工具奠定基础，以及为重新造林实践中的植物：真菌配对提供指导。总的来说，这些应该为全球努力了解土壤微生物在植物营养中的作用提供显着的好处。

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.
