Abstract
Intercropping with the legume Desmodium uncinatum almost completely protects maize crops grown in East Africa from the parasitic weed Striga hermonthica. We have shown this effect is not physically but allelochemically mediated within the rhizosphere of D. uncinatum. The project is to elucidate the chemistry of these rhizosphere interactions by isolating the bio-active compounds, determining their molecular structures and chemically synthesising them for structure confirmation and to examine their role in the rhizosphere ecology of the host-parasite interaction. Studies will also be made to understand the biochemical release of the active compounds into the rhizosphere, to facilitate future exploitation by plant molecular genetics.
