Abstract: This invention provides a novel family of plant phosphatases. Further provided are nucleic acids and nucleic acid constructs encoding the genes for plant phosphatases, cells containing the nucleic acids described and transgenic photosynthetic organisms with altered phosphate metabolism.

Abstract: A method for artificially changing the composition of phospholipids produced by cells is disclosed. According to the method of the invention, the host cell is transformed with a recombinant DNA having an antisense gene of phospholipase D gene, which antisense gene is expressed in the host cell to produce a mRNA that hybridizes with mRNA of phospholipase D gene in the host cell thereby inhibiting expression of the phospholipase D gene.

Abstract: Tomato LapA promoters and gene sequences are provided. The promoters are induced in plants upon wounding, or other stress-related conditions. The gene sequences include a full-length LapA gene, particularly the amino terminal region of the gene. Methods of making stress resistant plants, and of making plants susceptible to stress are provided.

Abstract: The present invention provides new gene expression regulatory DNA. This gene expression regulatory DNA comprises a promotor region derived from the barley D-hordein gene enabling the expression of a desired gene, and a regulatory region for regulating the expression of said gene based on said promoter region. This regulatory region consists at least of an activating region to activate the expression of said gene and a suppressing region to suppress the same.Use of this gene expression regulatory DNA enables controlling as desired the expression of gene within a plant cell such as barley.

Abstract: The invention provides a promoter capable of expressing an introduced gene in plant seeds, a vector comprising said promoter, a method for producing transgenic plants through transformation of plants with said vector, and a transgenic plant as transformed with said vector.After a suitable foreign gene and a terminator are linked to the promoter, the resulting vector may be introduced into seeds of barley or other plants, thereby intentionally modifying the seeds and making the resulting seeds produce foreign substances therein.

Abstract: The present invention provides a method for enhancing the expression of genes in plants by supplying a virally encoded booster sequence comprising the 5' proximal region of the potyvirus genome to the plant. The booster sequence enhances the expression of foreign genes or endogenous plant genes in plants by employing any known methodology of expressing introduced genes in plants. The booster sequence may be used to enhance expression of any gene, including foreign genes or endogenous plant genes, introduced by means of stable transformation into the genome of the plant or introduced by expression from a plant viral expression vector.

Abstract: This invention is in the field of corn breeding, specifically relating to a single cross dent corn hybrid designated as 5953. Hybrid 5953 is a variety especially bred for the north central United States having superior resistance to grey leaf blight.

Abstract: A synthetic hybrid corn plant having the designation P54, produced by crossing two proprietary DuPont TopCross International maize synthetics, LP39.1B-Lancaster and LP44.1A-Reid. P54 has the unique property of imparting high oil and high protein levels in the grain of certain normal and male sterile hybrids when used as a pollinator. P54 is characterized by excellent cold tolerant seedling vigor for rapid emergence in cold soils and excellent early-season adaptability facilitating nicking with early maize hybrids to condition fast dry-down and superior grain quality in the grain arising from the recipient female grain parent. This invention thus relates to the seeds, plants and plant parts of P54, to plants regenerated from tissue culture of the plants or plant parts of P54, to a method of producing P54, and to a method for producing high oil grain using P54 as a pollinator.

Abstract: A synthetic hybrid corn plant having the designation P55, produced by crossing two proprietary DuPont TopCross International maize synthetics, LP41.1B-Lancaster and LP44.1A-Reid. P55 has the unique property of imparting high oil and high protein levels in the grain of certain normal and male sterile hybrids when used as a pollinator. P55 is characterized by excellent cold tolerant seedling vigor for rapid emergence in cold soils and excellent early-season adaptability to nick with early maize hybrids that condition fast dry-down and superior grain quality in the recipient female grain parent. This invention thus relates to the seeds, plants and plant parts of P55, to plants regenerated from tissue culture of the plants of P55, to a method of producing P55, and to a method for producing high oil grain using P55 as a pollinator.
