Genetic engineering of cantaloupe to reduce ethylene biosynthesis and control ripening.

The T3 bacteriophage gene product S-adenosylmethionine hydrolase (SAMase) catalyses the degradation of SAM, a precursor to ethylene biosynthesis. Because both SAM and ethylene play a number of important roles in normal plant growth and development, a synthetic promoter was designed to restrict SAMase expression to the ripening fruit of cantaloupe. The ripening phenotype of cantaloupe transformed with a fruit-specific SAMase expression construct was analyzed in greenhouse and field trials. Results indicate that the genetically modified cantaloupe expressing SAMase exhibited modified postharvest characteristics, including a dramatic reduction in ethylene synthesis.
