Patent ID: 7078591

Claim:
A method of modifying development of a plant comprising transforming a plant cell with a nucleic acid encoding a plant cyclin-dependent kinase inhibitor polypeptide to produce a transformed plant cell, wherein the nucleic acid comprises the nucleic acid sequence set forth in SEQ ID NO: 1, SEQ ID NO: 3, or a nucleic acid sequence having at least 95% sequence identity with the nucleic acid sequence set forth in SEQ ID NO: 1 or SEQ ID NO: 3; and, growing the transformed plant cell or progeny of the transformed plant cell to produce a transformed plant under conditions wherein the plant cyclin-dependent kinase inhibitor polypeptide is expressed in a proliferative tissue of the transformed plant to bind to a plant cyclin-dependant protein kinase or a plant cyclin to inhibit development of a differentiated tissue in the plant.
