Abstract
A genetic construct comprising an SAG12 promoter sequence operably connected to a protein-coding DNA sequence not natively connected to the promoter sequence is disclosed. Preferably, this SAG12 promoter sequence is the first 602 bp of SEQ ID NO:2 and the protein-coding sequence encodes isopentenyl transferase.

A genetic construct comprising an Arabidopsis-derived SAG12 or SAG13 promoter sequence operably connected to a protein-coding DNA sequence not natively connected to the promoter sequence.
A genetic construct comprising an Arabidopsis-derived SAG12 promoter operably connected to a DNA sequence encoding an enzyme catalyzing the synthesis of cytokinin.
A genetic construct comprising an Arabidopsis-derived SAG13 promoter operably linked to a DNA sequence encoding an enzyme catalyzing the synthesis of cytokinin.
A transgenic plant with delayed senescence, the plant comprising in its genome, 5' to 3', a genetic construction comprising a senescence associated promoter and a coding region for an enzyme catalyzing the synthesis of a cytokinin, wherein the promoter is Arabidopsis-derived SAG13.
A transgenic plant having delayed senescence characteristics comprising in its genome
- a foreign genetic construction which comprises 5' to 3',
- a senescence specific promoter,
- a protein coding region for an enzyme which when expressed will catalyze the production of a cytokinin in the cells of the plant, and
- a transcriptional termination sequence,
- wherein the foreign genetic construction is expressed in tissues entering senescence to delay the senescence of the plant tissues and wherein the promoter is Arabidopsis-derived SAG 12-1.
