  1. Honours Projects 2013Jason Terpolilli • I am part of the Centre for Rhizobium Studies in the School of Veterinary and Life Sciences (please note our new website is under construction) • My research focus is in plant-microbe interactions, and the root nodule bacteria • RNB (rhizobia) are unique in their ability to convert atmospheric N2 into plant-available N in symbiosis with legumes • Research in the area is driven by: • Requirements for highly efficient N2-fixing symbioses in agriculture, which reduce CO2-footprint of farming and reliance on chemical fertilisers • The integral place N2-fixation plays in nutrient cycling. • On the next few slides are some potential honours projects. If any of them interest you, or you have any questions about them, I encourage you to come and discuss them with me. Cheers Jason J.Terpolilli@murdoch.edu.au

  2. Optimising N2-fixing symbiotic interactions to improve crop productivity Sucrose Malate Infected plant cell TCA ATP & e- Bacteroid Gln Asn N2 NH3 Nitrogenase Phloem Xylem • Key research aims: • Understand what drives N2-fixation efficiency • Why are some symbioses highly efficient? • Identify genetic determinants • Apply these in the field • Overcome competition • Aggressive nodulation by resident soil rhizobia • Often fix little or no N • Is selective nodulation a solution? Effectiveness on Medicago truncatula
