Abstract

  • Legumes and rhizobia engage in a symbiotic relationship that revolves around the nutrient exchange of rhizobia derived nitrogen for legume synthesized carbon that increases the growth of both partners.

  • Here, we use quantitative polymerase chain reaction (qPCR) and compare our results to a traditional colony forming unit (CFU) method for analyzing rhizobial abundance in more complex populations.

  • First, we confirmed that qPCR yielded similar results to CFU estimation for rhizobial populations within individual nodules and then found that genotypes that fix more nitrogen increased in population proportion over time

  • These experiments demonstrate the utility of qPCR for future experiments interested in analyzing rhizobia genotype proportions and how they relate to the level of benefits legumes receive.
