    摘要: The present invention provides for the expression of phytase in transgenic plants or plant organs and methods for the production of such plants. DNA expression constructs are provided for the transformation of plants with a gene encoding phytase under the control of regulatory sequences which are capable of directing the expression of phytase. These regulatory sequences include sequences capable of directing transcription in plants, either constitutively, or stage and/or tissue specific, depending on the use of the plant or parts thereof. The transgenic plants and plant organs provided by the present invention may be applied to a variety of industrial processes either directly, e.g. in animal feeds or alternatively, the expressed phytase may be extracted and if desired, purified before application.

    摘要: A nucleic acid having (i) a DNA molecule which, when expressed in a plant or plant cell, increases the trehalose content of the plant or plant cell, the DNA molecule encoding an E. coli trehalose phosphate synthase, and (ii) a plant expressible promoter operatively coupled to the DNA molecule. Also, a method for obtaining a plant with increased trehalose production by introducing into a recipient cell of a plant, a plant expressible gene which, when expressed in a plant or plant cell increases the trehalose content of the plant or plant cell. The plant expressible gene is an E. coli trehalose phosphate synthase gene which is operably linked to: a) a transcriptional initiation region that is functional in the plant, and b) a DNA molecule encoding a selectable marker gene that is functional in the plant. The method includes a step of regenerating a plant from the recipient cell under conditions that allow for selection for the presence of the selectable marker gene.
