A 16 bp polynucleotide sequence ofis a genetic insulator that can effectively isolate a transgene from positional effects of neighboring gene activities in transgenic plant cells.

Genetic insulator for preventing influence by another gene promoter

The present invention relates to a trichome specific regulatory sequence.

Plant trichome gland specific promoter sequence

The present invention comprises artificial nucleic acid constructs comprising a bidirectional promoter having minimal promoter and a common promoter, wherein said minimal promoters is operably linked to said common promoter, in opposite orientation to said common promoter, and 5&prime; to said common promoter. Those artificial nucleic acid constructs, wherein said bidirectional promoter further comprises at least one gene operably linked to said minimal promoter and said common promoter are preferred.

Bidirectional promoters and methods related thereto

The identification of senescence-specific promoters from plants is described. Using information from the first senescence-specific promoter, SAG12 from Arabidopsis, other homologous promoters from another plant have been identified. Such promoters may be used to delay senescence in commercially important plants.

Transgenic plants with altered senescence characteristics

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.
