Electron microscopic observations of the tsxs gene expression in Escherichia coli K12F- cells after conjugation with Hfr bacteria.
After matings between T6 sensitive (Tsxs) Hfr and T6 resistant (Tsxr) F- cells, the Tsxs zygotes have been observed by electron microscopy: They adsorb a small number of T6 particles if compared to what is observed several generations later. Moreover, the T6 receptors synthesized by these zygotes are not located randomly but in a central region of the cell surface.
