A plant material comprises a genomic nucleotide sequence encoding a SUSIBA2 or SUSIBA2-like transcription factor under transcriptional control of a promoter active in the plant material. The genomic nucleotide sequence encoding the SUSIBA2 or SUSIBA2-like transcription factor lacks at least a portion of an activation region of a SUSIBA1 or SUSIBA1-like promote represent in an intron of a wild-type version of the genomic nucleotide sequence encoding the SUSIBA2 or SUSIBA2-like transcription factor. The plant material has a controlled production of carbohydrates, in particular starch or starch and fructan. In particular, the plant material can be designed to produce carbohydrates at enhanced levels.

The present invention relates to transgenic plants with altered photorespiration and improved CO.sub.2 fixation as well as a method of producing said transgenic plants.
