Abstract
This document provides methods and materials related to plants having modulated (e.g., increased) levels of sugars (e.g., glucose, fructose, and/or sucrose). For example, this document provides plants having increased sugar levels as well as methods and materials for making plants and plant products having increased sugar levels.
Claims23
A method of modulating the level of a sugar in a plant, said method comprising a) introducing into a plurality of plant cells an isolated nucleic acid comprising a nucleic acid sequence encoding a polypeptide having 95 percent or greater sequence identity to an amino acid sequence set forth in SEQ ID NO:2;
- and b) selecting a plant produced from said plurality of plant cells that has a different sugar level as compared to a sugar level in a corresponding control plant that does not comprise said isolated nucleic acid.
A method of modulating the level of a sugar in a plant, said method comprising introducing into a plant cell (a) a first isolated nucleic acid comprising a nucleic acid sequence encoding a polypeptide having 95 percent or greater sequence identity to the amino acid sequence set forth in SEQ ID NO:2;
- and (b) a second isolated nucleic acid comprising a nucleic acid sequence encoding a polypeptide having 95% percent or greater sequence identity to an amino acid sequence set forth in SEQ ID NO:14;
- wherein a plant produced from said plant cell has a different sugar level as compared to a sugar level in a corresponding control plant that does not comprise said first isolated nucleic acid or said second isolated nucleic acid.
A method of producing a plant having a modulated level of a sugar, said method comprising (a) introducing into a plurality of plant cells an isolated nucleic acid comprising a nucleic acid sequence encoding a polypeptide having 95 percent or greater sequence identity to an amino acid sequence set forth in SEQ ID NO:2;
- (b) selecting a plant produced from said plurality of plant cells that has a different sugar level as compared to a sugar level in a corresponding control plant that does not comprise said isolated nucleic acid;
- and (c) growing said plant.
A method of producing a plant having a modulated level of a sugar, said method comprising (a) introducing into a plant cell a first isolated nucleic acid comprising a nucleic acid sequence encoding a polypeptide having 95 percent or greater sequence identity to an amino acid sequence set forth in SEQ ID NO:2, and a second isolated nucleic acid comprising a nucleic acid sequence encoding a polypeptide having 95 percent or greater sequence identity to an amino acid sequence corresponding to SEQ ID NO:14;
- and (b) growing a plant from said plant cell.
A plant comprising an exogenous nucleic acid, said exogenous nucleic acid comprising a nucleotide sequence encoding a encoding a polypeptide having 95 percent or greater sequence identity to an amino acid sequence set forth in SEQ ID NO:2, wherein said plant has a sucrose content that is increased at least 7% as compared to the sucrose content in a corresponding control plant that does not comprise said exogenous nucleic acid.
A plant comprising (a) a first exogenous nucleic acid comprising a nucleic acid sequence encoding a polypeptide having 95 percent or greater sequence identity to an amino acid sequence set forth in SEQ ID NO:2;
- and (b) a second exogenous nucleic acid comprising a nucleic acid sequence encoding a polypeptide having 95 percent or greater sequence identity to an amino acid sequence corresponding to SEQ ID NO:14;
- wherein said plant has a different sugar level as compared to a sugar level in a corresponding control plant that does not comprise said first exogenous nucleic acid or said second exogenous nucleic acid.
