DNA ENCODING A PLANT DEOXYHYPUSINE SYNTHASE, A PLANT EUKARYOTIC INITIATION FACTOR 5A, TRANSGENIC PLANTS AND A METHOD FOR CONTROLLING SENESCENCE AND PROGRAMMED CELL DEATH 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.
