A proposed nomenclature and classification for plant pathogenic bacteria.
Many names of plant pathogenic bacteria will not be included in the approved lists (1980) if the lists contain only the names of valid spp. It is proposed that pathogens which do not have a claim to sp. rank be classified as pathovars. All validly published names of plant pathogens for which there are authentic cultures are listed as spp. or as pathovars. A guide for using the term pathovar at the infrasubspecific level is suggested. Designated type and reference strs. are listed and neotype and new reference strs. are suggested where none has been reported elsewhere.
