Abstract
Relatedness in species of
Erwinia
was assessed by determining the extent of reassociation in heterologous deoxyribonucleic acid preparations. Thermal elution chromatography on hydroxyapatite was used to separate reassociated nucleotide sequences from nonreassociated sequences and to determine the thermal stability of related nucleotide sequences. An apparent 15% core of relatedness is present between fire blight, soft-rot, and “atypical”
Erwinia
species. All
Erwinia
species showed low to moderate reaction with representative enteric bacteria.
