DNA encoding a plant lipase, transgenic plants and a method for controlling senescence in plants

摘要

An isolated DNA molecule encoding senescence-induced lipase, wherein the DNA molecule has at least 90% sequence similarity to sequences disclosed from Dianthus caryophyllus and Arabidopsis thaliana; vectors for the transformation of plant cells; a transgenic plant cell and a transgenic plant comprising the vector; and methods for inhibiting expression of an endogenous senescence-induced lipase in a plant, methods for delaying age-related senescence and environmental stress-related senescence in a plant, methods for inhibiting seed aging; and methods of increasing seed yield form a plant using the DNA molecule or antisense polynucleotides having at least 90% sequence similarity to the complement of sequences disclosed.
