Citrus Variegated Chlorosis (CVC), caused by Xylella fastidiosa subsp. pauca bacterium, is one of the most concerning diseases for the Brazilian citriculture. It is responsible for economic damages around 100 million dollars a year in eradication of diseased plants, replanting, and chemical control of the vectors. CVC is a typical Brazilian problem since in other South or Central American countries, where the disease has already been reported, the citrus industry is not as important as it is in Brazil. Therefore it is a role of the research here in Brazil to study and propose alternatives for the control and/or propose a more efficient and sustainable management with reduced production costs. In these 15 years from the X. fastidiosa genome sequencing much basic knowledge was generated, turning it into one of the ten most studied bacteria in the world. However, few of these studies focused on the interactions among the components of this pathosystem, bacterium-plant-vector. This project aims at the integration of groups that work with X. fastidiosa to enlarge and associate the information of the genetic mechanisms that contribute to the adaptation efficiency of the bacterium, the relationship between colonization in the host and disease expression, the molecular interaction with the insect vector, and the genetic responses of the plant that could be used in medium or long term to control the damages caused by CVC in a more sustainable way and with reduced production costs. In addition to X. fastidiosa, the project proposes to expand the studies to Xanthomonas citri subsp. citri, the causal agent of Citrus Canker disease. This disease has become a greater problem in São Paulo orchards, due to recent changes in regulation regarding the control of Citrus Canker. Thus, because of the similarities between the two plant pathogens and common host, some approaches and control strategies will be used for both plant pathogens X. fastidiosa and X. citri. (AU)
