Rhizobium leguminosarum bv. viciae 3841 (Rlv3841) establishes nitrogen-fixing symbiosis with Viciae legumes such as agriculturally important pea (Pisum sativum). Rlv3841 is able to exist both as a free-living organism and as a nitrogen-fixing symbiont within root nodules. In the progression between these two states it experiences a number of lifestyle changes: growth in the rhizosphere, competing for root proximity, attachment and colonisation, and terminal differentiation into a nitrogen-fixing bacteroid. In my DPhil project I have used a mariner-based transposon vector for high-throughput insertion sequence mutagenesis to characterize the fitness determinants for these different lifestyle changes in Rlv3841 on the whole-genome scale.

    Wow! Sounds complicated. Googled you to check I had the right face, and I did. Thanks for your email again Rachel. It really means a lot. Owen Mansfield.
