INTERACCIONES HOSPEDANTE PATóGENO: LOGROS Y PERSPECTIVAS EN CUBA

food production worldwide is among the priorities of governments and institutions. the overall strategy for improving crop yields with less environmental impact, reduction of chemical application and preservation of biodiversity is geared towards sustainable agriculture. resistant varieties are a tactic widely used in integrated pest management; thus breeding programs are a priority for achieving this goal. understanding of the pathogens and the physiological bases, and the molecular and genetic interactions governing the plants may contribute to achieve durable resistance. in this complex scenario, a group of research works studying the interactions between hybrid saccharum spp., solanum lycopersicum l., oryza sativa l., and different pathogens was developed at the national center for agricultural health (censa), for over 25 years. the results are reported in this paper.
