Abstract

Takahashi, I. (McMaster University, Hamilton, Ontario, Canada). Joint transfer of genetic markers in Bacillus subtilis. J. Bacteriol. 91:101–105. 1966.—To compare the processes of genetic incorporation in transduction and transformation in Bacillus subtilis, several groups of linked markers were selected and the degree of linkage was determined by the two means of genetic exchange. Bacteriophage PBS 1 was used in transduction experiments. In all cases, frequencies of joint transfer, as expressed by the cotransfer index or by percentage of joint transfer, were higher in transduction than in transformation. With a pair of closely linked markers, the frequency of joint transduction was only slightly higher than that of joint transformation. On the other hand, a considerably higher degree of linkage was obtained by transduction when loosely linked markers were examined. It appears that the size of donor chromosome transferred by transducing phage particles is much larger than that incorporated by recipient cells in transformation. It is suggested that transduction in B. subtilis may be a useful tool in extending further the linkage groups established by the transformation technique.
