Title:	Expression of the Chlorella sorokiniana sedoheptulose 1,7-bisphosphatase in transgenic plants
Abstract:	Sedoheptulose 1,7-bisphosphatase (SBPase) is an enzyme catalyzing the reaction converting sedoheptulose 1,7-bisphosphate into sedoheptulose 7-phosphate. This enzyme is located in the chloroplast in leaves and stems. Overexpression of the Chlorella sorokiniana SBpase in transgenic plants is provided to improve plant yield by increasing leaf starch biosynthetic ability in particular and sucrose production in general.

Application Number:	09/569,771
Patent Claims:	1. A method for enhancing the assimilation of carbon in a plant comprising the steps of: a). inserting into the genome of a plant cell a nucleic acid sequence comprising in the 5' to 3' direction and in operable linkage, i). a promoter that functions in the cell, ii). a structural nucleic acid sequence comprising the nucleotide sequence of SEQ ID NO:20 or encoding SEQ ID NO: 12, wherein the structural nucleic acid sequence encodes a sedoheptulose 1,7-bisphosphatase enzyme from Chlorella sorokiniana, and iii). a 3' non-translated nucleic acid sequence that functions in said cell to cause transcriptional termination, to obtain a transformed plant cell containing the nucleic acid sequence and b). regenerating from said transformed plant cell a transformed plant that overexpresses said sedoheptulose 1,7-bisphosphatase enzyme in said plant in a manner that enhances the assimilation of carbon in said plant when compared to that of a non-transformed plant. 2. The method of claim 1, wherein said plant is a monocotyledonous plant. 3. The method of claim 1, wherein said plant is a dicotyledonous plant. 4. The method of claim 1, wherein said plant is selected from the group consisting of maize, wheat, cotton, soybean, canola, alfalfa, potato, sunflower, sugarbeet and rice. 5. The method of claim 1, wherein said nucleic acid sequence further comprises a 5' untranslated leader sequence. 6. The method of claim 1, wherein said nucleic acid sequence further comprises an intron. 7. An isolated nucleic acid sequence comprising, in operable linkage (a) a promoter that functions in the cells of a plant, (b) a structural nucleic acid sequence comprising the nucleotide sequence of SEQ ID NO:20 or encoding SEQ ID NO:12 in sense orientation, wherein the structural nucleic acid sequence encodes and a sedoheptulose 1,7-bisphosphatase enzyme, and (c) a 3' non-translated nucleic acid sequence that functions in said cells of said plant to cause transcriptional termination; wherein said promoter or said 3' non-translated nucleic acid sequence is heterologous to said structural nucleic acid sequence. 8. The method of claim 7, wherein said nucleic acid sequence further comprises a 5' untranslated leader sequence. 9. The method of claim 7, wherein said nucleic acid sequence further comprises an intron. 10. An isolated nucleic acid sequence comprising the nucleotide sequence of SEQ ID NO:20 or encoding SEQ ID NO: 12.
