Abstract: This invention relates generally to plant cells and/or plants with increased yield as compared to a corresponding non-transformed wild type plant cell by increasing or generating one or more activities of polypeptides associated with the intermediate phosphoribosylpyrophosphate (PRPP) in plants. In particular, this invention relates to plant cells and/or plants with increased yield as compared to a corresponding non-transformed wild type plant cell by increasing or generating one or more activities of phosphoribosyl pyrophosphate synthases (PRPP synthetase, PRS) The invention also deals with methods of producing and screening for and breeding such plant cells and/or plants.

Abstract: The invention relates to methods for increasing the oil content in plants, preferably in the seeds of plants, by expression of glycerol-3-phosphatdehydrogenases (G3PDH) from yeast, preferably from Saccharomyces cerevisiae. The invention also relates to expression constructs for the expression of G3PDH yeast in plants, preferably in the seeds of plants, transgenic plants expressing G3PDH, and to the use of said transgenic plants in the production of foodstuffs, feed, seeds, pharmaceuticals or fine chemicals, especially in the production of oils.
