  • Method of modifying plant characters by the targeted expression of a cell cycle control protein
    Publication number: 20030172404
    Abstract: This invention provides a method for modifying plant growth and development comprising expressing an isolated nucleic acid sequence encoding Cdc25 or a homologue, analogue or derivative thereof in one or more plant cells, tissues or organs operably under the control of a regulatable promoter that does not confer expression throughout the plant under all conditions.

  • Control of plant cell proliferation and growth
    Patent number: 6087175
    Abstract: The present invention is directed to a method for controlling plant cell growth comprising modulating the level and or catalytic activity of a cell cycle control protein in a plant cell for a time and under conditions sufficient to control cell division. Preferably, the cell cycle control protein is p34.sup.cdc2 or p34.sup.cdc2 -like molecule having a cyclin related kinase function and the plant is a monocotyledonous plant or dicotyledonous plant. The present invention is also directed to other cell cycle control proteins, so termed since they function similarly to p34.sup.cdc2 or control p34.sup.cdc2 activity. Such proteins include p13.sup.suc1, cyclin, cdc25, and the products of nim1, wee1 and mik-1 or combinations thereof, separately, or together with p34.sup.cdc2.
