Abstract: Methods for using cyclin-dependent kinase (CDK) inhibitor genes, or anti-sense constructs complementary to such genes, to modify the growth and development of plant cells and organs are disclosed. Also provided are methods of modifying the development of plant cells and plants by transforming plant cells with nucleic acids encoding cyclin-dependent kinase inhibitor polypeptides, or anti-sense constructs complementary to such nucleic acids, to produce transformed plant cells, and then culturing the plant cells or regenerating a plant under conditions wherein the cyclin-dependent kinase inhibitor, or the anti-sense construct, is expressed. A variety of CDK inhibitor genes, and corresponding anti-sense constructs, are disclosed for use in a variety of plants. The nucleic acid encoding the cyclin-dependent kinase inhibitor may be operably linked to a tissue-specific promoter. Other provided aspects are modified transgenic plants and plant tissues.
