Xanthomonas citri
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 into X. citri. However, based on the principle of priority, all "X. citri" should become instead named under the earliest-published name, X. cissicola like in GTDB. 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.
Pathovars included
Uncited entries are based on Bansal et al., either in the article's own results or in its description of earlier results. Pathovars that include the type strain of either X. citri or X. cissicola are shown in bold.The list is unlikely to be complete.
