β¦ Synopsis
Pulsed-field gel electrophoresis (PFGE) was used to show that insertions of transposon Tn4560 in Streptomyces lividans 66 and the avermectin-producer S. avermitilis are randomly distributed. DNA from the latter strain suffered degradation during electrophoresis that could be avoided by modification of the buffer. Inverse PCR primers were developed for Tn4560.

We constructed a plasmid pR4C1 in which a DNA fragment containing the cohesive ends of an actinophage, R4 was inserted into the ClaI site of plasmid pIJ365. The plasmid pR4C1 was packaged efficiently into R4 phage particles in vivo and therefore transferred by transduction. Southern hybridization an
