  • Publication number: 20080131896
    Abstract: Methods for plant transformation, for improving transformation efficiency, and for producing transgenic plants are provided. The methods comprise crossing a recipient plant from a genetic line of a plant species of interest with a donor plant selected from a transformation competent genetic line of the same plant species or of another closely related plant species to obtain a hybrid plant. Tissues obtained from the hybrid plant are transformation competent. These tissues can then be transformed with one or more nucleotide sequences of interest and selected for transgenic events having the nucleotide sequence of interest integrated within a chromosome derived from the recipient plant. Transformed cells can be selected and transgenic hybrid plants regenerated. The nucleotide sequence of interest can be introgressed into the genetic line from which the original recipient parent was derived, or into other genetic lines. Transformed plants and seeds are additionally provided.

  • Patent number: 6452069
    Abstract: The present invention provides compositions and methods for regulating expression of heterologous nucleotide sequences in a plant. Compositions are novel nucleotide sequences for pollen-preferred promoters isolated from a gene unit for SF3. A method for expressing a heterologous nucleotide sequence in a plant using the promoter sequences disclosed herein is provided. The method comprises transforming a plant cell to comprise a heterologous nucleotide sequence operably linked to one of the pollen-preferred promoters of the present invention and regenerating a stably transformed plant from the transformed plant cell.

  • Patent number: 6441275
    Abstract: Methods for increasing resistance in plants to pathogens by the expression of a hydrogen peroxide/reactive oxygen species producing enzyme or an oxalate degrading enzyme. The present invention relates to a method of producing a pathogen resistant hybrid plant by crossing the appropriate transgenic expressing a hydrogen peroxide/reactive oxygen species producing enzyme or an oxalate degrading enzyme with pathogen tolerant lines or inbreds obtained through conventional genetic manipulations, or by transformation of tolerant plants or plant tissues with a hydrogen peroxide/reactive oxygen species producing gene or by altering the expression of an endogenase hydrogen peroxide/reactive oxygen species producing gene. The synergistic effect of expression of a hydrogen peroxide/reactive oxygen species producing enzyme or an oxalate degrading enzyme in a tolerant background gives significant and unexpectedly high resistance to the pathogens.

  • Patent number: 6337100
    Abstract: Antisense expression of a stearoyl-ACP desaturase gene in sunflower results in more than a four-fold increase in seed stearate, and can enhance palmitate content as well. Thus, sunflower oil containing over 40 percent saturated fatty acids can be produced, which is desirable in the context of various products, such as coating fat, margarine, soap and shortening.
