    • 🧍 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. Hauben et al. 1999 propose (1) to restrict the genus Erwinia to the species of cluster I (see: Erwinia); (2) to transfer the species of cluster III into the new genus Brenneria Hauben et al. 1999; (3) to unite the species of cluster II, Erwinia carotovora subsp. atroseptica, Erwinia carotovora subsp. betavasculorum, Erwinia carotovora subsp. carotovora, Erwinia carotovora subsp. odorifera, Erwinia carotovora subsp. wasabiae, Erwinia cacticida, Erwinia chrysanthemi and Erwinia cypripedii in the genus Pectobacterium Waldee 1945 (Approved Lists 1980); (4) to emend the genera Pectobacterium [Pectobacterium Waldee 1945 (Approved Lists 1980) emend. Hauben et al. 1998] and Erwinia [Erwinia Winslow et al. 1920 (Approved Lists 1980) emend. Hauben et al. 1998]; (5) to emend the species Pectobacterium carotovorum [Pectobacterium carotovorum (Jones 1901) Waldee 1945 (Approved Lists 1980) emend. Hauben et al. 1998], Pectobacterium chrysanthemi [Pectobacterium chrysanthemi (Burkholder et al. 1953) Brenner et al. 1973 (Approved Lists 1980) emend.
