“Background Xanthomonas axonopodis pv. citri (X. a. pv. citri) is a gram-negative plant pathogenic bacteria that causes citrus canker [1]. This phytopathogen invades host plant tissues entering through stomata or wounds and then colonizes the apoplast of fruits, foliage and young stems and symptoms of infection appear as raised corky lesions. At the final stage, plant tissue epidermis is broken due to cell hyperplasia, which allows bacterial dispersal to other plants by windblown rain. Persistent and severe disease can lead to defoliation, dieback and fruit drop thereby reducing yields, and hence causing serious economic losses.
