  • Patent number: 5886164
    Abstract: A method of modifying ethylene biosynthesis in a plant comprises inserting into the genome of the said plant a DNA sequence such as SEQ-ID-NO-1 (encoding 1-aminocyclopropane-1-carboxylic acid synthase (ACS)) and/or sequence SEQ-ID-NO-2 (encoding an ethylene-forming enzyme (EFE)) which modifies the activity of at least one of ACS or EFE.
