Abstract

Tn5 lac 삽입으로 채소입고병원균에 길항력이 약화된 T-67 및 고추역병균과 참깨역병균에 길항력이 약화된 T-81의 Tn5 lac 유전자 일부와 오른쪽 말단에 있는 길항관련 유전자의 flanking sequence가 cloning된 pAG67 및 pAG81 clone을 선발하였고, pAG67 및 pAG81 clone된 길항관련 유전자의 flanking sequence를 야생 길항균 Pseudomonas maltophilia B-14의 DNA를 probe로 사용하여 Southern hybridization으로 확인하였으며, 제한효소 지도를 작성하여 8Kb 및 4Kb 크기의 flanking sequence가 cloning되었음을 확인하였다. pAG6 및 pAG81의 flanking sequence를 EcoRi-BglII와 EcoRI-MpaI으로 분리하여 유전자 은행으로부터 길항관련 유전자가 cloning된 cosmid clone 7개주를 선발하였다.
