Three‐Partner Symbiosis among Legumes, Mycorrhizae, and N‐Fixing Bacteria Changes with Light and Soil Nitrogen Conditions.

All partners were more successful in the gaps (under higher light availability), but light only had a positive effect on AMF when nitrogen was added and plants invested less in nitrogen-fixing bacteria. Three-Partner Symbiosis among Legumes, Mycorrhizae, and N-Fixing Bacteria Changes with Light and Soil Nitrogen Conditions Seedlings planted under gap conditions were located here, and seedlings planted under understory conditions were in adjacent intact forest.
