How DNA encoding deoxyhypusine synthase in a plant, eukaryotic initiation factor 5A in plants, transgenic plants, and to control programmed cell death and senescence in plants

摘要

Regulation of expression of programmed cell death, including senescence, in plants is achieved by integration of a gene or gene fragment encoding senescence-induced deoxyhypusine synthase, senescence-induced elF-5A or both into the plant genome in antisense orientation. Plant genes encoding senescence-induced deoxyhypusine synthase and senescence-induced elF-5A are identified and the nucleotide sequences of each, alone and in combination are used to modify senescence in transgenic plants.
