Abstract: A plant promoter that is a nucleic acid region located upstream of the 5' end of a plant DNA structural coding sequence that is transcribed at high levels in meristematic tissue and/or rapidly dividing cells. This promoter region is capable of conferring high levels of transcription in meristematic tissue and/or rapidly dividing cells when used as a promoter for a heterologous coding sequence in a chimetic gene. The promoter and any chimeric gene in which it may be used can be used to obtain transformed plants or plant cells. A DNA coding sequence that codes for a gene that is highly transcribed in meristematic tissue of Arabidopsis thaliana is also disclosed. This coding sequence can be used to obtain a cDNA probe useful in obtaining analogous promoters from a homologous coding sequence in other plant species. Chimeric genes including the isolated promoter region, transformed plants containing the isolated promoter region, transformed plant cells and seeds are also disclosed.

Abstract: A method for Agrobacterium-mediated transformation and regeneration of soybean is disclosed. The method utilizes a cotyledon explant which is prepared by first removing the hypocotyl and then tearing the two cotyledons apart at the cotyledonary node. The explant may be inoculated with either a smear of the disarmed Agrobacterium vector or of liquid culture of the bacterium.

Abstract: In one aspect the present invention relates to the use of viral promoters in the expression of chimeric genes in plant cells. In another aspect this invention relates to chimeric genes which are capable of being expressed in plant cells, which utilize promoter regions derived from viruses which are capable of infecting plant cells. One such virus comprises the cauliflower mosaic virux (CaMV). Two different promoter regions have been derived from the CaMV genome and ligated to heterologous coding sequences to form chimeric genes. These chimeric genes have been shown to be expressed in plant cells. This invention also relates to plant cells, plant tissue, and differentiated plants which contain and express the chimeric genes of this invention.

Abstract: Plants can be transformed to express glucose oxidase from Aspergillus sp. and be made resistant to bacterial and fungal pathogens. Optionally, the plants may also express invertase to increase the available glucose as a substrate for enzymatic activity.

Abstract: A method for controlling the ripening of fruits and vegetables as well as a method for controlling senescence of plant tissue is described. The method generally embraces the expression of an ACC metabolizing enzyme in the fruit or other desired plant tissue to inhibit the production of ethylene in the fruit or plant tissue. The use of the ACC metabolizing enzyme ACC deaminase is described in detail. The ripening or senescence process in the fruit or plant tissue is inhibited by the expression of the ACC deaminase gene such that the shelf-life and marketability of the fruit or plant is enhanced. The ACC metabolizing enzyme may be used in combination with other methods for reducing ethylene production in transformed plants to further reduce the production of ethylene in the fruit or plant. DNA constructs containing the ACC deaminase gene are also described.
