Abstract
DNA-DNA hybridization by kinetic method was carried out between species of purple nonsulfur photosynthetic bacteria and nonphotosynthetic bacteria. The degrees of homology percent were shown to be low (2-35 D%) with the exception of high homology % (72-88 D%) for strains within a species and between Rhodobacter capsulatus and Rhodopseudomonas blastica. The D% between the purple nonsulfur photosynthetic bacteria, Rhodopseudomonas palustris, and nonphotosynthetic bacteria, Pseudomonas aeruginosa ATCC 27853 or Bradyrhizobium japonicum were a little higher (26-33 D%) than the D% between any other photosynthetic bacteria. The homology % between Rhodopseudomonas blastica and Rhodobacter capsulatus was 72 D%, which showed genetic relationship.
광합성 세균과 비광합성 세균에 속하는 종들 사이의 유연관계를 파악하기 위해 DNA 혼성화 방법을 실시하였다. 혼성화도는 종내 균주들 사이와 Rhodobacter capsulatus와 Rhodopseudomonas blastica 사이를(72-88%) 제외하고는 전체적으로 낮게 나타났다(2-35%). 광합성 세균 Rhodopseudommonas Palustris와 비광합성 세균 Pseudomonas aeruginosa ATCC 27853, Bradyrhizobium japonicu, 사이의 D%는 광합성 세균 사이의 D%보다 약간 높게 나타났다(26-33%). Rhodopseudomonas blastica와 Rhodobacter capsulatus 사이의 D%는 72%로 유전적 유연관계가 매우 높은 것으로 나타났다.
