The present invention relates to the generation and cultivation of plant cell material in the form of a non-tissue multilayer cell pack and its use for the accumulation or harvesting of a desired product. In particular, the invention provides a method for the generation of plant cell material in the form of a medium-deprived, porous structured and non-tissue multilayer cell pack and for the subsequent maintenance of said cell pack, comprising the steps of (i) providing a cell pack by separating cells from a plant cell suspension culture, wherein the content of the liquid comprised by the cell pack is reduced and adjusted to correspond to a cell pack density between 0.1 and 0.9 g wet cell weight per cm3, thereby establishing the medium-deprived and porous structured nature of said cell pack, and (ii) incubating said medium-deprived and porous structured cell pack in a non-liquid environment under a relative humidity of 50 to 100%.

Method for the generation and cultivation of a plant cell pack

The invention relates to a method for the production of plants with suppressed photo-respiration and improved COfixation. In particular, the invention relates to a re-use of phosphoglycolate produced in photorespiration. The reaction product will be converted to a component that may be reintegrated into the plant assimilatory metabolism inside the chloroplast. This is accomplished by the transfer of genes derived from glycolate-utilizing pathways from bacteria, algae, plants and/or animals including humans into the plant nuclear and/or plastidial genome. The method of the invention leads to a reduction of photorespiration in Cplants and by this will be of great benefit for food production especially but not exclusively under non-favourable growth conditions.
