GENE-TRANSFER BETWEEN STREPTOMYCETES IN SOIL
UNSPECIFIED (1992) GENE-TRANSFER BETWEEN STREPTOMYCETES IN SOIL. In: 8TH INTERNATIONAL SYMP ON BIOLOGY OF ACTINOMYCETES ( ISBA-8 ), AUG 11-16, 1991, UNIV WISCONSIN, MADISON, WI.Full text not available from this repository.
The growth and activity of Streptomyces violaceolatus and Streptomyces lividans was studied in soil under controlled conditions. The life cycle was followed under differing nutrient regimes and the fate of plasmid- and phage-borne genes determined by direct and indirect techniques. Methods were developed for the direct monitoring of plasmid DNA extracted from soil which allowed differentiation of the cellular location of plasmid DNA between mycelium and spores. In a dynamic, nutrient-fed soil microcosm, inoculants survived poorly, but a specific stage was defined by direct and indirect methods when the inoculants were most active and this correlated with the detection of gene transfer events. Plasmid transfer, phage infection and lysogeny only occurred to a significant extent within this stage at days 15-17 during a 60-day incubation. Estimates based on plasmid DNA recovery indicated that viable counts underestimated spore and mycelial propagules by a factor of > 100.
