Motte Rimrock Reserve

13 Jan, 01 AM - 13 Jan, 03 AM

We hope to examine potential effects of nitrogen deposition on legume/rhizobia symbiosis. Our study plant is Lotus strigosus, common in western Riverside County. Rhizobia fix nitrogen for legumes. We are interested in the evolution of this trait. Theory predicts that in the presence of excess nitrogen there is a potential for rhizobia to 'cheat', not fixing nitrogen for their hosts. The assumption is that since the plant has sufficient nitrogen it does not enforce symbiotic benefits from the bacteria. We intend to examine symbiosis at sites with varying levels of nitrogen depostion.
