Summary

The RNA antisense technology allows the blocking of specific genes expression and the later observation of the effects on the phenotype. A laboratory has generated a type of Cantaloupe Charentais melon antisense ACC oxidase, the enzyme which catalyses the last reaction of the ethylene synthesis, the fruit ripening hormone. The ethylene production in this kind of transgenic fruit is strongly reduced, more than 99.5% in comparison to the wild type, and, as a consequence, some processes characteristic of the ripening period are inhibited. This model of transgenic fruit allows studying the role of ethylene in the development of the chilling injury physiopathy, which takes place in fruits stored at low temperatures.
