Xanthomonas citri pv. citri (XANTCI. - EPPO Global Database.

Xanthomonas species can cause bacterial spots and blights of leaves, stems, and fruits on a wide variety of plant species. Pathogenic species show high degrees of specificity and some are split into multiple pathovars, a species designation based on host specificity. Citrus canker, caused by Xanthomonas citri subsp. citri is an economically important disease of many citrus species (lime.

Identification and characterisation of Xanthomonas.

Pathogen. Xanthomonas axonopodis pv.citric (synonym: Xanthomonas campestris pv.citri) is a gram negative, aerobic, rod-shaped bacterium that causes citrus canker.This pathogen generally causes leaf-spotting and fruit rind-blemishing disease. Highly favorable conditions can lead to more severe infections that result in shoot dieback and fruit drop.

About

Xanthomonas citri subsp. citri (X. citri) is a Gram-negative bacterium and the etiological agent of citrus canker, a severe disease that affects all the commercially important citrus varieties with worldwide distribution. The best method to control the spread of this plant pathogen, which happens by the combined action of wind and rain, is the eradication of symptomatic and asymptomatic trees.

Xanthomonas axonopodis pv. citri (Xac) is the causative agent of citrus canker. This bacterium develops a characteristic biofilm on both biotic and abiotic surfaces. To evaluate the participation of the single flagellum of Xac in biofilm formation, mutants in the fliC (flagellin) and the flgE (hook) genes were generated. Swimming motility, assessed on 0.25 % agar plates, was markedly reduced.
