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 virus (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: A class of heterologous dominant conditional lethal genes is disclosed. The gene is useful in genetically modifying plant cells and plants to selectively induce cellular lethality for purposes such as inducing male sterility for hybrid seed production, cell ablation and counter-negative selection.

Abstract: This invention involves a cloning or expression vector comprising a gene which encodes 5-enolpyruvylshikimate-3-phosphate synthase (EPSPS) polypeptide which, when expressed in a plant cell contains a chloroplast transit peptide which allows the polypeptide, or an enzymatically active portion thereof, to be transported from the cytoplasm of the plant cell into a chloroplast in the plant cell, and confers a substantial degree of glyphosate resistance upon the plant cell and plants regenerated therefrom.The EPSPS coding sequence may be ligated to a strong promoter, such as the 35S promoter from cauliflower mosaic virus, to create a chimeric gene. Such genes can be inserted into plant transformation vectors, and subsequently introduced into plant cells. Plant cells transformed using such genes and plants regenerated therefrom have been shown to exhibit a substantial degree of glyphosate resistance.

Abstract: Transgenic plants are disclosed which are resistant to virus infection by Potato Virus X and Potato Virus Y. Plant genes and transformation vectors are also disclosed. Potato plants, for example, Russet Burbank variety, are made resistant to dual infection by Potato Virus X and Potato Virus Y by transforming the plant to express the coat proteins of the two viruses.
