Nitrogen addition does not influence pre-infection partner choice in the legume-rhizobium symbiosis.

PREMISE OF THE STUDY Resource mutualisms such as the symbiosis between legumes and nitrogen-fixing rhizobia are context dependent and are sensitive to various aspects of the environment, including nitrogen (N) addition. Mutualist hosts such as legumes are also thought to use mechanisms such as partner choice to discriminate among potential symbionts that… CONTINUE READING
