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.
通过测定异源脱氧核糖核酸制剂中的重新结合程度来评估欧文氏菌属物种之间的亲缘关系。利用羟基磷灰石上的热洗脱色谱法将重新结合的核苷酸序列与未重新结合的序列分离,并确定相关核苷酸序列的热稳定性。在火疫病、软腐病和“非典型”欧文氏菌属物种之间存在明显15%的核心亲缘关系。所有欧文氏菌属物种与代表性肠道细菌的反应都呈现出低到中等程度。
