ABSTRACT
Relation between induced mutations of plasmid pAP18-1 (Tc, Col) and alterations in it's restriction map was studied. Nitrosoguanidine induced mutations of transfer regulation system and incompatibility of this plasmid related with alteration in the situation of recognition sites for restrictases EcoR1 and Sal1 in map positions 42.2-4.3 and 12.9-17.9 MD. Insertions of transposons Tn5 and Tn9 into the plasmid DNA resulted in a decrease of incompatibility level.
