TL;DR
The fractions of Escherichia coli female and male bacteria that are competent to form specific mating pairs at any time during normal exponential growth have been measured by a physical assay.
Abstract
The fractions of Escherichia coli female and male bacteria that are competent to form specific mating pairs at any time during normal exponential growth have been measured by a physical assay. The competencies of a Hayes- and a Cavali-type donor were 35 and 50%, respectively, in agreement with piliation assays reported by others. The competencies of two recipient strains, PA309 and P678, were found to be 33 and 29%, respectively.

A large number of Gene Loci have been identified that have shown the ability to transfer from E.coli to E. Coli through contact chemoreception, a process known as “correlation of Cotransduction Frequency with Map Distance in Minutes”.

It is suggested that genes exist which simultaneously mediate a female-specific mating site, ampicillin resistance, and the receptors for phage phiW.

There is a considerable spread in the time at which transfer is initiated in the different mating pairs, and the presence of broth in the medium in which transfer takes place leads to a marked reduction in the stability of pairs involving some Hfr cells, but has little or no effect on pairs involving others.
Journal of BacteriologyRole of Pili in Bacterial Conjugation
86 Citations1970Jonathan T. Ou, Thomas F. Anderson
It is concluded that F pili play at least three roles in mating: (i) they initiate contacts between mating pairs; (ii) they facilitate the transfer of genetic material; and (iii) they draw mating cells into a close contact which increases the fertility of the union.

Findings are compatible with the hypothesis that donor cells have a single surface structure involved in both conjugation and male-phage adsorption and that this element is the F pilus.

Rough mutants of Salmonella typhimurium LT-2 which had increased recipient abilities for the conjugal transfer of foreign deoxyribonucleic acids are isolated by using rough-specific phages (personal communication) and it is shown that there are several types of these mutants.

The results with inogenic factor V seem to indicate that this factor replicates in of bacteria autonomously and at a faster rate than the chromosome, which would apply to their state in F- bacteria.

The yield and the rate of recombinants formed by mating of synchronized female cells of E. coli depends on the position of recipient cells in the division cycle, since purine starvation inhibits DNA, ribonucleic acid, and protein synthesis, and reduces all metabolic processes where adenosine triphosphate is involved.
