Abstract
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 eIF-5A or both into the plant genome in antisense orientation. Plant genes encoding senescence-induced deoxyhypusine synthase and senescence-induced eIF-5A are identified and the nucleotide sequences of each, alone and in combination are used to modify senescence in transgenic plants.
Claims6
A vector comprising a DNA molecule encoding
- (a) a tomato senescence-induced eIF-5A, wherein the DNA molecule is at least 70% homologous to SEQ ID NO:11, and wherein the senescence-induced eIF-5A has translation initiation factor activity;
- and
- (b) regulatory sequences operatively linked to the DNA molecule such that eIF-5A is expressed in a plant cell into which it is transformed.
A vector comprising a DNA molecule encoding (a) senescence-induced eIF-5A, wherein the DNA molecule comprises SEQ ID NO:11;
- and (b) regulatory sequences operatively linked to the DNA molecule such that the eIF-5A is expressed in a plant cell into which it is transformed.
An isolated DNA molecule encoding tomato senescence-induced eIF-5A, wherein the DNA molecule has at least 70% sequence identity with SEQ ID NO:11 and wherein the senescence-induced eIF-5A has translation initiation factor activity.
An isolated DNA molecule encoding tomato senescence-induced eIL-5A, wherein the DNA molecule comprises SEQ ID NO:11.
