Abstract

Plant nematode gene function can be assessed by RNAi techniques. We have shown effective prolonged effects of a single pre-infection RNAi treatment on establishment, development and fecundity of M.incognita. Our RNAi target was dual oxidase, shown in C. elegans to be involved in tyrosine cross- linking in the extracellular matrix (ECM). This establishes the ECM as a potent target for resistance strategies. ECM biosynthesis is critical during the moulting stages in maturation of plant nematodes. We will test different dsRNA constructs for efficacy by in planta infection assays to guide development of transgenic plants expressing effective RNAi constructs. We will test further ECM-related genes for their efficacy in disrupting nematode development. These studies will provide further understanding of ECM processes in plant nematodes.
