Abstract: The invention provides isolated plant gene promoters and regulatory elements that are root specific and/or induced by plant parasitic nematodes. The promoters of the invention are useful for controlling expression of nucleic acids of interest in plant roots and are particularly useful for controlling transcription of nucleic acids encoding agents that disrupt formation or maintenance of parasitic nematode feeding sites in plants.

Abstract: The invention provides isolated promoter polynucleotides that are root-specific and/or induced by plant parasitic nematodes. The promoters of the invention are useful for controlling expression of nucleic acids of interest in plant roots and are particularly useful for controlling transcription of nucleic acids encoding agents that disrupt formation or maintenance of parasitic nematode feeding sites in plants.

Abstract: The invention provides plant gene promoters and regulatory elements that are root-specific and/or induced by parasitic nematodes. The promoters of the invention are useful for controlling expression of nucleic acids of interest in plants' roots. The invention also provides expression cassettes including the plant gene promoters and regulatory elements of the invention, transgenic plants containing such expression cassettes, and methods of producing such transgenic plants.

Abstract: The present invention provides compositions of matter comprising plant-operable promoter sequences that confer selective/specific endosperm expression on genes to which they are operably connected and uses of such compositions to confer gene expression, especially in developing endosperm.

Abstract: This invention provides cyanobacteria as an alternative source of ahas and pds genes for plant transformations and for selectable markers. In particular, it provides for cyanobacteria, for example, Synechocystis, as a source of genes encoding herbicide insensitive proteins, and elements of genes for control of expression in plastids. Nucleic acid fragments, both the acetolactate synthase (ahas) large subunit and the ahas small subunit, were found to provide herbicide resistance. Also, the present invention provides novel Synechocystis mutant phytoene desaturase (PDS) gene conferring resistance to 4?-fluoro-6[(alpha,alpha,alpha,-trifluoro-m-tolyl)oxy]-picolinamide, a bleaching herbicide. The present invention provides improvements to method involving cyanobacteria for the screening of compounds, including a new high-through-put protocol that is a rapid and cost effective way to identify target site genes.

Abstract: This invention provides an alternative source of ahas and pds nucleic acids for plant transformation and selection. In particular, the invention provides ahas and pds nucleic acids from cyanobacteria, for example, Synechocystis, and expression elements of these genes for control of expression in plastids. The invention further provides nucleic acids encoding the acetolactate synthase (ahas) large subunit and the ahas small subunit which were found to provide herbicide resistance to plants. The present invention also provides a novel Synechocystis mutant phytoene desaturase (PDS) gene conferring resistance to 4?-fluoro-6-[(alpha, alpha, alpha,-trfluoro-m-tolyl)oxy]-picolinamide, a bleaching herbicide. The present invention provides improved methods involving cyanobacteria for the screening of compounds, including a new high throughput protocol that is a rapid and cost effective way to identify target site genes.
