Conteúdo: | Meloidogyne incognita is a nematode responsible for huge losses of economically important crops. The control of this pathogen is heavily centered on chemical nematicides, which are toxic to humans and environment, besides being very expensive. Alternatively, resistant varieties of cotton generated from conventional breeding programs represent an attractive strategy for the control of M. incognita. In this context, the goal of the work reported here was to analyze the gene expression profile of one resistant and one susceptible cotton genotype infected with M. incognita aiming to understand the mechanisms involved in resistance. EST libraries of cotton in both resistant and susceptible to infection by M. incognita were constructed and sequenced, generating 2261 sequences that were assembled into 233 contigs and 1593 singlets. Genes differentially expressed were observed in both resistant and susceptible cotton. Twenty genes were found to be expressed exclusively in the resistant cotton genotype, with functions related to pathogen recognition, signal transduction, defense mechanisms and protein synthesis transport and activation. The coordinated action of these genes suggests the existence of a complex defense pathway towards nematode attack in cotton. Our data indicate some candidate genes for validation and use through transformation in other agronomically important plants.
