[Differentiation genes are involved in homologous recombination in Streptomyces coelicolor].

In S. coelicolor, the rapid increase of SCP2* plasmid conjugation efficiency and that of plasmid homologous recombination efficiency associates with development of aerial mycelium. Results of test of SCP2* plasmid conjugation and plasmid homologous recombination in one bld mutant and in three whi mutants show that while whiA mutant causes unstable plasmid conjugation efficiency, the other three mutants show no influence on plasmid conjugation, plasmid homologous recombination efficiency drops however more than 10 times in the four mutants.
