Plant parasitic nematodes (PPNs) seriously threaten global food security. Conventionally an integrated approach to PPN management has relied heavily on carbamate, organophosphate and fumigant nematicides which are now being withdrawn over environmental health and safety concerns. This progressive withdrawal has left a significant shortcoming in our ability(More)
Entomopathogenic nematodes (EPNs) employ a sophisticated chemosensory apparatus to detect potential hosts. Understanding the molecular basis of relevant host-finding behaviours could facilitate improved EPN biocontrol approaches, and could lend insight to similar behaviours in economically important mammalian parasites. FMRFamide-like peptides are enriched(More)
Plant parasitic nematodes (PPN) locate host plants by following concentration gradients of root exudate chemicals in the soil. We present a simple method for RNA interference (RNAi)-induced knockdown of genes in tomato seedling roots, facilitating the study of root exudate composition, and PPN responses. Knockdown of sugar transporter genes, STP1 and STP2,(More)
12 Here we present a simple and rapid new method for RNAi-induced knockdown of genes in 13 tomato seedlings, through treatment with an aqueous solution of double-stranded RNA 14 (exoRNAi). The exoRNAi method is used to assess the involvement of tomato Sugar 15 Transporter Protein genes, stp1 and stp2 on the root exudation of glucose, fructose and 16 xylose;(More)
