Abstract
The present invention relates to a method for plant genome modification of at least one plant cell being in the developmental stage of a plant immature inflorescence meristem (IIM) cell, wherein the modification of the specific cell type is achieved by providing a genome modification or editing system, optionally together with at least one regeneration booster, preferably wherein the effector molecules are introduced by means of particle bombardment. To this end, new artificial and precisely controllable booster genes and proteins are provided. Further, the modified plant cells are regenerated in a direct or an indirect way. Finally, methods, tools, constructs and strategies are provided to effectively modify at least one genomic target site in a plant cell, to obtain said modified cell and to regenerate a, plant tissue, organ, plant or seed from such modified cell.
