Taxonomic repositioning of twelve Xanthomonas campestris, seven Xanthomonas axonopodis and one Pseudomonas cissicola reference pathovars to Xanthomonas citri

Abstract

Here on the basis of phylo-taxonogenomics criteria we present amended description of 20 pathovars to Xanthomonas citri majority (18/20) of which were first reported from India. 7/20 are currently classified as X. axonopodis, 12/20 as X. campestris and 1/20 as Pseudomonas cissicola. Here, we have generated genome sequence data for 4 pathovars and genomes of remaining 16 were used from the published data. Genome based investigation reveals that all these pathovars belong to X. citri and not to X. axonopodis or X. campestris as previously reported. Present proposal is to aid in resolving the taxonomic confusion of the X. ctiri pathovars and prevent future usage of invalid names.
