Research Program Summary

  • Molecular Plant-Microbe Interactions

The legume-Rhizobium symbiosis is of great importance in providing fixed nitrogen, both in agriculture and natural ecosystems. The level of interaction between host plants and bacterial symbiont range from intimate, highly evolved interactions to those others that approach parasitism. This range of complex associations provides an ideal system for the study of plant-microbe interactions.

Current and Recent Student Research Projects

  • Characterization of bean mutation that selectively prevents nodulation in common beans: an opportunity to improve nitrogen fixation
  • Plant gene expression during nodule senescence; limitation on and regulation of nitrogen fixation
  • Involvement of plant “defense” genes in maintaining the balance between symbiont and parasite
  • Characterization of peanut nodulation as an example of a more “primitive,” yet extremely efficient, interaction
