Transfer of RP4:Mu cts from E. coli to Rhizovium leguminosarum
RP4:Mu cts의 E.coli로 부터 Rhizovium leguminosarum으로의 전달
Abstract
In order to use for recipient strains of RP4:Mu cts, 5 strainsof Rhizobium were selected among 32 strains, which were isolated and identified in this study. Hybrid plasmin RP4::Mu cts, which, is temperature sensitive and confers resistance to ampicillin, kanamycin and tetracycline was transfered by conjugation from E. coli to other atrains of C. coli and the symbiotic nitrogen fixer, Rhizobium leguminosarum. Transfer frequencies of RP4::Mu cts plasmid from E. coli to Rhizobium were about
우리나라 자연환경으로부터 분리한 Rhizob ium 32권주로부터 카나마이신, 세트라싸이클린 등에는 예민하고, 클로람페니콜, 젠타마이신 등에는 강한 내성을 나타내는 5 균주를 선별하고, 이를 수용세포로하여 RP4::Mu cts를 접함에 의해 E. coli로부터 Rhizobium leguminosarum으로 전달 시켰다. 그 전달빈도는
