Abstract:
1. A method for increasing the expression level of pyruvate orthophosphate dikinase (PPDK) in a C4 plant, comprising the steps of: (i) transforming the C4 plant using an expression cassette that comprises: a promoter; an isolated DNA from a 04 plant genome encoding PPDK, operably linked to said promoter; and a terminator; wherein said DNA comprises a nucleotide sequence having at least 98% sequence identity to the nucleotide sequence as set forth in nucleotides 1732-8508 of SEQ ID NO:15 and encodes a protein having PPDK activity; and (ii) expressing said DNA in said C4 plant, wherein expression of said PPDK is increased in the C4 plant.
