Résumé : Citrus bacterial canker (CBC) is a severe disease affecting citrus worldwide. Mediterranean area if free of CBC, ORPRAMed project aims at assessing the introduction risk of CBC through Citrus rutaceous relatives (CRR), especially those not covered by 2000/29EC Directive. Despite the high agricultural significance of CBC, there are not recent and in depth studies about the interaction between CRR and Xanthomonas citri subsp. citri (Xcc) and Xanthomonas fuscans subsp. aurantifolii (Xfa), causal agents of CBC. The project consortium includes Italian, Spanish, French and Turkish research centres and universities with expertise from agriculture economics to plant pathology and genomics. A selection of CRR will be assayed for the resistance/susceptibly to CBC, moreover rutaceous spedies trade flows will be investigated, as well as the survival mechanisms and fitness on CRR of Xcc and Xfa strains representative of their pathological and genetic diversity. Finally, the genome of Murraya paniculata (sel.2 from Florida Citrus Arboretum, Winter Haven, Florida, USA) will be sequenced as well as transcriptomic analysis performed to highlight the main genes involved in the disease. The project results will contribute to update information on the trade of Rutaceae, acquire new data on the behaviour of ornamental Rutaceae regarding Xcc, expand the knowledge about the epi-endophytic colonization of the pathogen and update the European import-export regulation on plant protection.
