Methods are provided for the genetic control of pathogen infestation in host organisms such as plants, vertebrate animals and fungi. Such methods utilize the host as a delivery system for the delivery of genetic agents, preferably in the form of RNA molecules, to a pathogen, which agents cause directly or indirectly an impairment in the ability of the pathogen to maintain itself, grow or otherwise infest a host plant, vertebrate animal or fungus. Also provided are DNA constructs and novel nematode nucleotide sequences for use in same, that facilitate pathogen resistance when expressed in a genetically-modified host. Such constructs direct the expression of RNA molecules substantially homologous and / or complementary to an RNA molecule encoded by a nucleotide sequence within the genome of a pathogen and / or of the cells of a host to effect down-regulation of the nucleotide sequence. Particular hosts contemplated are plants, such as pineapple plants, and particular pathogens are nematodes.

A method of transferring a gene to vertebrate cells is disclosed. The method comprises the steps of: (a) providing microprojectiles, the microprojectiles carrying polynucleic acid sequences, the sequences comprising, in the 5' to 3' direction, a regulatory sequence operable in the tissue cells and a gene positioned downstream of the regulatory sequence and under the transcriptional control thereof; and (b) accelerating the microprojectiles at the cells, with the microprojectiles contacting the cells at a speed sufficient to penetrate the cells and deposit the polynucleic acid sequences therein. Preferably, the target cells reside in situ in the animal subject when they are transformed. Preferred target cells are dermis or hypodermis cells, and preferred genes for insertion into the target cells are genes which code for proteins or peptides which produce a physiological response in the animal subject.
