interactions, Plant nutrition
Nitrogen (N) is the major limiting factor in agriculture and the largest input cost for non-leguminous crops, which can account for up to 60% of the production costs. For maize, yield performance is mainly dependent on N fertilization. However, this extensive use of N affects ecosystems and represents an important environmental threat. Nitrogen nutrition may be optimized with the help of soil-borne microbes such as nitrogen fixing bacteria or mycorrhizal fungi. Optimizing the use of N by plants using soil-borne microbes is the focus of our projects. We develop genomic and physiological approaches to tackle this issue.
