Abstract: The present invention relates generally to methods for generating plants having altered phenotypes, and to plants so generated and parts of these plants. More particularly, the present invention relates to a method for modifying a plant so as to produce a plant exhibiting an altered phenotype. Particularly useful altered phenotypes contemplated by the present invention include plants having altered tissue architecture. The present invention further contemplates genetic sequences capable of facilitating the modification of a phenotype of a plant and to sequences complementary thereto and to derivatives of the sequences. Plants and parts of plants, such as flowering and reproductive parts including seeds, also form part of the present invention. The ability to modify the phenotype of a plant may be useful for, inter alia, producing plants with more highly desired characteristics, such as delayed flowering, increased lateral branching, delayed senescence and the like.

Abstract: 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.

Abstract: A method is disclosed for constructing a synthetic polynucleotide from which a protein is selectively expressible in a target cell of a plant, relative to another cell of the plant. The method comprises selecting a first codon of a parent polynucleotide for replacement with a synonymous codon which has a higher translational efficiency in the target cell than in said other cell, and replacing said first codon with said synonymous codon to form said synthetic polynucleotide.
