homotypic synonym, validly published under the ICNP
Pectobacteriumrhapontici is the correct name if this species is regarded as a separate species (i.e., if its nomenclatural type is not assigned to another species whose name is validly published, legitimate and not rejected and has priority) within a separate genus Pectobacterium.
Pectobacterium rhapontici (Millard 1924) Patel and Kulkarni 1951 (Approved Lists 1980) and Erwinia rhapontici (Millard 1924) Burkholder 1948 (Approved Lists 1980) have the same type strain and therefore are homotypic synonyms [Rules 24a and 24b (1)]. — The species of the genus Erwinia Winslow et al. 1920 (Approved Lists 1980) may be divided into three phylogenetic groups according to the results of 16S rDNA sequences (see: Erwinia). Hauben et al. 1999 propose (1) to restrict the genus Erwinia to the species of cluster I, Erwinia amylovora, Erwinia mallotivora, Erwinia persicina corrig., Erwinia psidii, Erwinia rhapontici and Erwinia tracheiphila; (2) to emend Erwinia rhapontici [Erwinia rhapontici (Millard 1924) Burkholder 1948 (Approved Lists 1980) emend. Hauben et al. 1998]. So, Pectobacterium rhapontici is to be considered as an authentic erwinia.Publication:
