Disruption of CKX3 and at least one other CKX gene in a plant or plant cell leads to improved traits

摘要

The present invention is directed to isolated plant cells and transgenic plants comprising a disruption in at least a CKX3 gene and in one further gene encoding for a cytokininoxidase/dehydrogenase and being different from CKX3 well as to methods of producing such transgenic plants and to methods of increasing seed yield in a plant and/or plant height.
