Methods for Elevating Fat/Oil Content in Plants

a technology of fat/oil content and plant cells, applied in the direction of transferases, peptide sources, enzymology, etc., can solve the problems of low abundance of lipid droplets, difficult production of oils in non-seed plant tissues for industrial applications, and insufficient understanding of transient accumulation of stored oils in non-seed tissues, etc., to improve the lipid content of genetically modified plant cells, increase the lipid content of cellular lipid droplets, and reduce lipa activity

Abstract

In some embodiments, the present invention provides a method of elevating lipid content in vegetative (non-seed) plant or algal cells, plant tissues, or whole plants by genetically modifying the plant or algae to express a protein or polypeptide associated with lipid metabolism (such as fat-specific protein 27) of animal origin or plant origin. Also provided are genetically-modified plant or algal cells, plant tissues, or whole plants with elevated cellular lipid content, expressing a protein or polypeptide associated with lipid metabolism (such as fat-specific protein 27) of animal (e.g. human) origin or plant origin.

Description

CROSS-REFERENCE TO RELATED APPLICATION

[0001] The present application claims the benefit of U.S. Provisional Application Ser. No. 61 / 739,499, filed Dec. 19, 2012, and U.S. Non-provisional application Ser. No. 13 / 830,012, filed Mar. 14, 2013, both of which are hereby incorporated by reference in their entirety, including any figures, tables, or drawings.BACKGROUND OF THE INVENTION

[0002] Plants are a primary source of human and / or animal food, excellent feedstock for fuels, and useful for production of desirable chemicals. Plants synthesize and store lipids, primarily, in cytosolic lipid droplets. In plants, seeds are the primary site of oil synthesis and storage; vegetable oils (such as triacylglycerol) are used as a form of energy during seed germination. Vegetable oils can be synthesized in non-seed (such as leaf) tissues; however, their abundance is low and the stored lipids are presumed to be metabolized rapidly, perhaps for the recycling of fatty acids for energy or the synthesis o...
