About this work
Alfalfa (Medicago sativa) grown with nitrogen during preflight testing as part of Dissecting Beneficial Plant-Microbe Interactions and their Efficacy in the ISS Spaceflight Environment, a Model Study (Veg-06). This investigation examines spaceflight’s effects on the interactions between plants and nitrogen-fixing bacteria called rhizobia. These bacteria can take up nitrogen gas from the air and convert it into ammonia, a form of nitrogen plants can use for growth.
