Conteúdo: | The worldwide citrus production has been affected by adverse environmental conditions and serious phytosanitary problems. Among the diseases, huanglongbing (HLB) can be highlighted, since it quickly disseminates amongst orchards and affects all commercial varieties of citrus, that is, there is no reported resistance towards HLB within Citrus spp. In addition, vector-mediated transmission is efficient. As a result, several research groups around the world have pursued different strategies to better understand this pathosystem, through the plant-pathogen-vector interactions and their mechanisms of action. The strategies sought by the scientific community range from more appropriate crop management, including the use of biological control agents, to powerful biotechnology tools that could be used to mitigate disease prevalence and spread. Here we point out some of these different approaches with promising results that are being studied by researchers around the Globe. Moreover, we describe some of the strategies, aimed at controlling HLB by eliminating or reducing bacterial growth and preventing vector transmission. Among the research lines, the search for HLB resistant or tolerant varieties has been carried out for several years through conventional breeding, through transgenic or viral vector-derived approaches and, more recently, through genome editing.
