High-frequency conjugation associated with Streptococcus lactis donor cell aggregation.
Conjugal transfer of the Streptococcus lactis 712 lactose plasmid was found to occur at a low frequency. Variants of this plasmid were selected which had much greater donor abilities and which also exhibited an unusual cell aggregation phenotype.
