MANIPULATION OF PLANT SENESCENCE USING AN MYB GENE PROMOTER AND CYTOKININ BIOSYNTHESIS GENES

摘要

The present invention relates to methods of manipulating senescence in plant s. The invention also relates to vectors useful in such methods, transformed plants with modified senescence characteristics and plant cells, seeds and other parts of such plants. Specifically the present invention provides a method of manipulating senescence in a plant, said method including introducing into said plant a genetic construct including a myb gene promote r, or functionally active fragment or variant thereof, operably linked to a gen e encoding an enzyme involved in biosynthesis of a cytokinin, or a functionall y active fragment or variant thereof.
