Abstract: The present invention provides transgenic algal cells that produce an increased amount of oil, methods of making transgenic algal cells, and methods of obtaining biofuel from the transgenic algal cells.

Abstract: The invention provides methods and compositions for the production of transgenic plants, plant cells, embryos, and seeds that produce plants with floral organs that have increased mass and/or size as compared to wild-type plants.

Abstract: The present invention provides recombinant promoters that drive tissue-specific expression, and transgenes comprising such recombinant promoters. Specifically, the invention provides transgenes comprising a recombinant promoter that drives tissue-specific expression of a heterologous nucleic acid molecule in a floral organ. The invention also provides methods for using such transgenes to produce a protein in a host cell or transgenic plant. The invention further provides methods for producing a transgenic plant that produces, for example, longer-lasting flowers, better fragrance, or better or longer-lasting color as compared to a wild type plant.

Abstract: The present invention relates to the altering or controlling inhibition of gene expression in a cell using a methodology involving a dsRNA. The use of the method in plants and plant cells has been found to be particularly beneficial. For example the inhibition of a hormone signaling gene in a plant, such as the EIN2 gene, permits the modulating of flower longevity in the selected plant. This is accomplished by using our RNAi technology in inhibiting the expression of an ethylene-modulated gene or an ethylene signaling gene in plants and plant cells. This method provides for the use of RNAi technology in inhibiting the expression of a hormone signaling gene in a plant, particularly in the floral parts of a plant. Thus, one can modulate flower longevity in a plant.
