A method for increasing resistance to physiological disease in a plant comprises integrating into the genome of the plant a vector comprising an antisense nucleotide and a regulatory sequences operatively linked to the antisense nucleotide sequences such that the antisense nucleotide sequences are expressed, and then growing the plant, whereby said antisense nucleotide sequences are transcribed and bind to the RNA sequence, whereby expression of said senescence-induced deoxyhypusine synthase gene, senescence-induced eIF-5A gene or both is inhibited. The antisense nucleotide sequences are selected from sequences encoding the 3'end of endogenous senescence-induced deoxyhypusine synthase, and encoding the endogenous senescence-induced eIF-5A gene.
