[DNA content in Streptoverticillium mucoheptinicum spores in the period of their germination].

Changes in the DNA content were studied in the spores of Streptoverticillium mycoheptinicum. The content of DNA increased in the spores when they were incubated in a liquid nutrient medium at 28 degrees C for 5 hours. Changes in the DNA content during germination of spores corresponded to individual stages: at the stage of activation, the replication of DNA only commenced; at the stage of initiation, the content of DNA doubled in the majority of spores in the population. The rate of DNA synthesis varied among different spores of the actinomycete.
