Abstract:
The present invention relates generally to the field of molecular biology and describes nucleic acids encoding regulatory elements capable of affecting expression of a coding sequence. The regulatory elements described herein may be used to direct the expression of a heterologous coding region in the green tissues and upon exposure to light in plants. The invention may also be used to create transgenic plants having increased yield.
Abstract:
The present invention relates to plant cells and plants, which are genetically modified, wherein the genetic modification leads to the reduction of the activity of a starch phosphorylating OKl protein in comparison with corresponding wild type plant cells or wild type plants that have not been genetically modified. The OKl protein acts as a phosphoglucan, water dikinase (PWD) which predominately phosphorylates the C3 position. Genetically modified plants in which the expression of PWD is reduced show a starch excess phenotype. Furthermore, the present invention relates to means and methods for the manufacture of such plant cells and plants. Plant cells and plants of this type synthesise a modified starch. The present invention therefore also relates to the starch synthesised by the plant cells and plants according to the invention, methods for the manufacture of this starch, and the manufacture of starch derivatives of this modified starch, as well as flours containing starches according to the invention. Furthermore, the present invention relates to nucleic acid molecules, which ar suitable for manufacturing plants according to the invention.
Abstract:
The invention provides non-naturally occurring microbial organisms containing a fatty alcohol, fatty aldehyde or fatty acid pathway, wherein the microbial organisms selectively produce a fatty alcohol, fatty aldehyde or fatty acid of a specified length. Also provided are non-naturally occurring microbial organisms having a fatty alcohol, fatty aldehyde or fatty acid pathway, wherein the microbial organisms further include an acetyl-CoA pathway. In some aspects, the microbial organisms of the invention have select gene disruptions or enzyme attenuations that increase production of fatty alcohols, fatty aldehydes or fatty acids. The invention additionally provides methods of using the above microbial organisms to produce a fatty alcohol, a fatty aldehyde or a fatty acid.

The present invention relates generally to the field of molecular biology and regards various polynucleotides, polypeptides and methods that may be employed to enhance yield in transgenic plants. Specifically the transgenic plants may exhibit increased yield, increased biomass or increased photoassimilation.
Abstract:
Cancer specific splicing events in the Wnt/ß -catenin signaling pathway are associated with progression of myelogenous leukemia. Misspliced genes of interest include GSK3ß. In some embodiments of the invention, polynucleotides are provided that correspond to misspliced GSK3ß transcripts associated with cancer. Such transcripts are characterized by a deletion of exon (8), and particularly in exon (8) and (9). Detection of such transcripts in cells is indicative of the presence of leukemia, and particularly of the presence of leukemia stem cells. In other embodiments, polypeptides are provided that are encoded by misspliced GSK3ß transcripts associated with cancer. Such polypeptides are useful as diagnostic markers for cancer, and as a target for screening of therapeutic agents. Animal models comprising a human LSC having a misspliced GSK3b transcript provide a useful model for leukemia, for drug/gene screening in the prevention and treatment of leukemia in humans, etc.
Abstract:
The present invention relates to genetically modified plant cells and plants, and to processes for the production of genetically modified plant cells and plants which have an increased activity of a protein having the activity of a starch synthase Il and an increased activity of a protein having the activity of a glucan-water dikinase. Plants of this type synthesize starches having increased hot water swelling power. The present invention likewise relates to starches having increased hot water swelling power, and to processes for their production.
Abstract:
Genetically engineered plants expressing altered Glucan Water Dikinase and having elevated levels of starch are provided. Methods of genetically engineering plants to express altered Glucan Water Dikinase, and genetic constructs are provided. Methods of breeding genetically engineered plants homozygous for a mutated gene encoding an altered Glucan Water Dikinase are described. Methods of agricultural processing and animal feed using the genetically engineered plants are also provided.
Abstract:
Recombinant microbial cells and methods for producing 5HTP, melatonin and related compounds using such cells are described. More specifically, the recombinant microbial cell may comprise exogenous genes encoding one or more of an L-tryptophan hydroxylase, a 5- hydroxy-L-tryptophan decarboxylyase, a serotonin acetyltransferase, an acetylserotonin O- methyltransferase; and means for providing tetrahydrobiopterin (THB), and can be further genetically modified to enrich one or more of tryptophan, S-adenosyl-L-methinonine and acetyl coenzyme A. Related sequences and vectors for use in preparing such recombinant microbial cells are also described.
Abstract:
The present invention provides for the manipulation of carbon flux in a recombinant host cell to increase the formation of desirable products. The invention relates to cellulose-digesting organisms that have been genetically modified to allow the production of ethanol at a high yield by redirecting carbon flux at key steps of central metabolism.
