Abstract: The invention provides a process for producing trehalose in plant cells capable of producing trehalase by growing plant cells having the genetic information required for the production of trehalose and trehalase, or cultivating a plant or a part thereof comprising such plant cells, characterized in that said plant cells are grown, or said plant or a part thereof, is cultivated in the presence of a trehalase inhibitor.

Abstract: The invention involves decreasing the intracellular availability of trehalose-6-phosphate by plant cell transformation with a gene encoding trehalose-6-phosphate phosphatase from E. coli. Phenotypic effects of plant transformation with this gene include stimulation of glycolysis, cell or tissue growth, and metabolism; and inhibition of photosynthesis and bolting.

Abstract: The present invention is directed to the production of male sterile plants by providing them with a recombinant DNA capable of specific expression in the male reproductive system of a plant of the enzyme trehalose phosphate phosphatase (TPP). Restoration of the fertility can be established either by providing said male sterile plants with a recombinant DNA capable of expression of trehalose phosphate synthase (TPS) under control of an inducible promoter or with a recombinant DNA capable of expression of a suppressor protein which suppresses expression of TPP under control of an inducible promoter. This inducible restoration possibilities enable the maintenance site-specific recombination system is provided, by inserting two site-specific recombination sites flanking the recombinant DNA coding for TPP and crossing the male sterile lines with lines expressing the corresponding recombinase. By crossing the recombinase will excise the gene coding for TPP and fertile hybrids are produced.

Abstract: This invention describes a method to prevent sprouting in vegetatively propagated plants such as potato, strawberry, banana and bulbous plants such as onion and bulbous flowers, by transforming a plant or a plant from one of its parental lines with a gene coding for trehalose phosphate synthase. Restoration of sprouting is also provided for.

Abstract: A method of modification of the development and/or composition of cells, tissues, or organs in vivo in plants by inhibiting the level of an endogenous trehalase is provided. The cells, tissues, or organs have been genetically altered to comprise a DNA sequence encoding a trehalase inhibitor. The DNA sequence is capable of expressing an RNA that is at least partially complementary to an RNA produced by a DNA sequence encoding the endogenous trehalase. Alternatively, the DNA sequence comprises a DNA sequence which is identical to a DNA sequence encoding the endogenous trehalase. The modification is other than to increase production or accumulation of trehalose.

Abstract: The present invention is directed to the production of male sterile plants by providing them with a recombinant DNA capable of specific expression in the male reproductive system of a plant of the enzyme trehalose phosphate (TPP). Resotration of the fertility can be established either by providing said male sterile plants with a recombinant DNA capable of expression of trehalose phosphate synthase (TPS) under control of an inducible promoter or with a recombinant DNA capable of expression of a suppressor protein which suppresses expression of TPP under control of an inducible promoter. This inducible restoration possibilities enable the maintenance of a homozygous male sterile line. Restoration can also be done by spraying the male sterile plants with gibberellic acid.

Abstract: This invention describes a method to prevent post-harvest sprouting in potato by transforming the potato plant with a gene coding for trehalose phosphate synthase.

Abstract: An isolated DNA fragment that promotes root knot or cyst nematode indcuible transcription of a coding sequence downstream of and operably linked to the fragment in at least an Arabidopsis thaliana plant and a chimeric DNA sequence including the DNA fragment. Also, methods for the use of the DNA fragment.

Abstract: A method for obtaining plants with reduced susceptibility to invasion by a plant parasitic nematode, and plants having reduced susceptibility to invasion by a plant parasitic nematode obtained, for example, with such method.
