Xanthomonas citri is a Gram-negative, rod-shaped bacterium. Although it is harmless for humans, it is a phytopathogen, known for being the causing agent of citrus canker.
Many pathovars are misclassified as X. cissicola, X. campestris, or X. axonopodis. A 2022 study proposes moving 20 pathovars in these three (including the sole representative of X. cissicola) into X. citri.[1] However, based on the principle of priority, all "X. citri" should become instead named under the earliest-published name, X. cissicola like in GTDB.[2] The two proposals do not affect the independence of X. campestris and X. axonopodis, as their type strains are sufficiently distinct from X. citri/cissicola to be their own species.
