摘要

Method for resistance to citrus diseases caused by insects, fungi or omicetos or by bacteria or nematodes.; It is to modify the levels of accumulation and monoterpenes and sesquiterpenes emission citrus mechanism as resistance against pathogens and pests. Alteration of the content of d-limonene and other terpenes is achieved by introducing via genetic transformation a gene encoding an enzyme with d-limonene synthase, either from a citrus or from another plant or organism, in or as antisense molecule inducing RNA interference (RNAi). Genetic modification is achieved either by Agrobacterium tumefaciens or any other method of genetic transformation of plants from protoplasts or explants from the plant. The construction is incorporated into citrus genotypes or related genera of the family Rutaceae in order to reduce the levels of accumulation and emission of the monoterpene and precursor compounds and / or derivatives at both leaves, flowers and fruit as.
