Plants exude a complex mixture of organic compounds from their roots, which alters the availability of plant nutrients and fuels diverse microbial communities that influence plant health and nutrition. Nutrient deficiencies affect large areas of agricultural land. Although they're known to strongly influence root exudation, these effects are poorly understood. Changes in root exudation could reduce crop yields by negatively affecting plant nutrient uptake and plant-microbe interactions. For this reason, better understanding of the effects of nutrient deficiencies on root exudation is needed to predict future food security.

In this project, you'll grow plants under different nutrient deficiencies and collect and analyse root exudates using advanced chromatography and mass spectrometry methods.
