Abstract

We explored the dynamics of simple artificial rhizobial populations by conducting a rhizobial passaging experiment and using qPCR. According to the sanctions hypothesis, we expect M. loti genotypes that fix more nitrogen to attain greater population sizes over time. We did not find support for the sanctions hypothesis for our mediocre and non–beneficial combination, but we did find support for the wildtype, mediocre, and non–beneficial strain combination. By utilizing a rapid, relatively cheap, and powerful technique, such as qPCR, future studies will be able to investigate the ecological dynamics of dozens of other M. loti mutants.
