Multiple Mating Types of Mycobacterium smegmatis
Open accessAbstract
Multiple mating systems were found in the strains of Mycobacterium smegmatis. Nineteen wild type strains were classified into five different groups according to their mating behavior. All crosses between substrains derived from the same wild type strain or between substrains belonging to the same group were infertile, while eight different intergroup crosses were fertile. It was suggested that in most of the fertile crosses, chromosome transfer was unidirectional. Genes controlling matings were resistant to curing by acridine dye, sodium dodecyl sulfate and higher temperature suggesting that they were chromosomal genes. However, the location of these genes could not be demonstrated because none of the chromosomal markers tested was found to be linked to these mating genes.

Distributive conjugal transfer (DCT) is a novel form of horizontal gene transfer first described in M. smegmatis.
“Distributive conjugal transfer (DCT) is a novel form of horizontal gene transfer (HGT) first described in M. smegmatis (39, 40).”
From Mycobacterium smegmatis: The Vanguard of Mycobacterial Research (2023) · cites this paper as [39]
The Segregation of Unselected Markers in Recombinants section (page not available in our copy) reports chromosomal gene transfer through mating in M. smegmatis. The Discussion reports multiple mating systems, but the paper does not identify this process as distributive conjugal transfer or establish that DCT was first described there. (LLM, conf=0.85)

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
