Abstract: .alpha.-Amylase, an enzyme that hydrolyses starch, can be found in all plants. The modification of potato starch production, in particular, is important in the preparation of various food products. The present invention discloses nucleotide sequences of potato .alpha.-amylase genes and the corresponding amino acid sequences. The present invention also describes DNA probes comprising .alpha.-amylase nucleotide sequences, as well as expression vectors that produce active .alpha.-amylase enzymes. These expression vectors can be used to produce transgenic potato plants.

Abstract: A carbon-based process for the selection of heterotrophically cultured plant cells is contemplated as are plants transformed using that process and a kit useful for effecting such a transformation. Plant cells are transformed with a heterologous DNA segment that contains two expression cassettes. The first cassette contains a gene that encodes a heterologous enzyme that on expression converts a growth-limiting (encrypted) carbon source that does not support growth and proliferation of non-transformed plant cells into a carbon source that supports growth and proliferation of transformed plant cells. The second cassette contains a second gene to be expressed in the transformed plant cells. A mixture transformed and non-transformed plant cells is cultured under heterotrophic culture conditions with the growth-limiting carbon source as the only carbon source.

Abstract: A process for integrating a DNA fragment into the genome of a cell of a monocotyledonous plant, the process comprising the steps of:1) incubating, prior to contacting with the DNA fragment, a culture of untransformed monocotyledonous plant cells on a medium comprising a plant phenolic compound, for a period of time sufficient to stimulate cell division and enhance competence for integration of foreign DNA; and2) contacting the untransformed cells with the DNA fragment under conditions in which the DNA fragment is taken up by the untransformed cells and is stably integrated in the genome of the untransformed cells, to generate transformed cells.

Abstract: A method for producing antibodies and plant protein toxins in plant cells is described which includes the steps of providing a genetic construct to encode the secretable protein, delivering copies of the construct into a liquid suspension culture of tobacco cells, selecting for cells that have acquired the genetic construct, and allowing the desired protein to accumulate in the liquid media in which the plant cells are grown, and isolating the desired protein away from the tobacco cells.

Abstract: The invention discloses methods of controlling one or more genes in plants. The genes may be exogenous genes and produce a desired phenotypic trait in the plants produced. The genes are operatively linked to a heterologous upstream activating sequence (UAS) recognition site, which is activatable by a transactivating protein. The genes linked to the UAS sequence, and nucleic acid encoding for the transactivating protein may originally be in separate transgenic plants, one of which fertilizes the other to produce reproductive material, such as seed, which may be grown into plants expressing the desired phenotype. The desired phenotype may be herbicide resistance or the production of a polyhydroxyalkanoate, such as polyhydroxybutyrate.

Abstract: The present invention provides a method for increasing the levels of essential amino acids in seeds of plants, thereby enhancing the nutritional value of the seeds. The method comprises manipulating the metabolic pathway of the amino acid to provide an increased source of the target free amino acid and, concomitantly, over-expressing a preselected gene coding for the protein containing the target amino acid, such that there is accumulation of protein-bound target amino acid. A complementary protein sink is thus produced. The present invention is particularly useful in increasing levels of methionine, lysine and threonine in seeds.
