Abstract
We have recently shown that myo-inositol is the principal sugar/polyol present in soil solution and secreted by legume roots. Myo-inositol catabolic mutants of R. leguminosarum form less than 1 per cent of nodules on legume hosts when in competition with the wildtype. These data indicate that myo-inositol has a particularly crucial role in growth and colonisation of the rhizosphere. We propose to investigate the colonisation of legume and non-legume (roots) by a panel of myo-inositol mutants of R. leguminosarum and a myo- inositol transport mutant Pseudomonas sp. JD54. This will enable the global importance of myo-inositol catabolism to root colonisation to be assessed.
