A method of modifying oil content of a plant is provided. The method comprising: (a) modulating activity or expression of a fructokinase (FRK) in seeds of a plurality of plants; and (b) selecting a seeds of the plurality of plants or progeny thereof exhibiting the modified oil content as compared to the oil content of seeds of the same species not subjected to step (a).

Disclosed herein are genetically engineered yeast cells capable of producing lactate from sucrose. The genetically engineered yeast cells comprise a polynucleotide encoding an exogenous lactate dehydrogenase enzyme: a polynucleotide encoding an exogenous invertase enzyme: a deletion or disruption of a native pyruvate decarboxylase (PDC) gene: and a genetic modification resulting in overexpression of a native hexokinase gene.

Recombinant strains are obtained for the production of allulose, allose, and allitol by regulating intracellular glucose metabolism, reducing the enzyme activity of fructose 6-phosphate kinase, and enhancing the enzyme activities of glucokinase and glucose-6-phosphate isomerase, allulose 6-phosphate 3-epimerase, allulose 6-phosphate phosphatase, fructose permease and fructokinase, and optionally enhancing the enzyme activities of ribose 5-phosphate isomerase, allose 6-phosphate phosphatase, ribitol dehydrogenase, glycerol permease, glycerol dehydrogenase, and dihydroxyacetone kinase. A method for producing allulose and allose is an extracellular multienzyme cascade method. Multienzyme cascade catalysis and fermentation are coupled to improve the conversion rate of starch sugar or sucrose to the synthesized allulose.

The present invention relates to oleaginous yeast strains overexpressing a hexokinase gene, wherein said strains are capable of accumulating lipids. Methods for obtaining said strains as well as methods for producing lipids are also disclosed.

The invention relates to transgenic plants exhibiting increased cell wall content. In one embodiment, transgenic plants engineered to over-express fructokinase (FRK) or both FRK and sucrose synthase (SuSy) are provided. The FRK+SuSy double-transgenic plants of the invention consistently exhibit enhanced cell wall polymer deposition.

Disclosed are genetically engineered microbial cells for the production of oligosaccharides comprising a galactose-1,4-glucose moiety at their reducing end, wherein said microbial cells are able to produce said oligosaccharides in the absence of exogenously added lactose, and a method of producing said oligosaccharides using said microbial cells.

Systems and methods for promoting cellular regeneration in ischemic tissue through administration of pyruvate kinase M2 or a substantially similar therapeutic to the ischemic tissue are disclosed herein.

The present disclosure relates to a microorganism of the genus Corynebacterium producing L-amino acid, a method for producing L-amino acid using the same, use of L-amino acid production, and a composition for producing L-amino acid.
