CARBON-NEUTRAL AND CARBON-POSITIVE PHOTORESPIRATION BYPASS ROUTES SUPPORTING HIGHER PHOTOSYNTHETIC RATE AND YIELD

摘要

The present invention relates to an organism, a tissue, a cell or an organelle expressing enzymes which allow the conversion of 2-phosphoglycolate (2-PG; also known as glycolate 2-phosphate) into an intermediate compound of the Calvin-Benson-Bassham Cycle (CBBC) without releasing CO₂. The organism, tissue, cell or organelle of the invention may be genetically engineered, transgenic and/or transplastomic so as to express at least one enzyme which is involved in this conversion. The present invention further relates to an organism, tissue, cell or organelle which comprises/expresses at least one enzyme which is involved in this conversion. The present invention further relates to a method for producing an organism, tissue, cell or organelle of the invention. The present invention further relates to a method of enzymatically converting 2-PG into an intermediate compound of the CBBC without releasing CO₂. The present invention further relates to the use of an organism, tissue, cell or organelle of the invention for enzymatically converting 2-PG into an intermediate compound of the CBBC without releasing CO₂.
