Genetic Recombination without Sexual Reproduction in Aspergillus niger

Pontecorvo, G., Roper, J. A., Forbes, E.·1953·Journal of General Microbiology

Abstract

SUMMARY: Roper’s technique for the production in filamentous fungi of strains with heterozygous diploid nuclei in their hyphae (Roper, 1952) has been applied successfully to Aspergillus niger, in which a sexual cycle does not occur. The diploids, heterozygous for known markers, give origin to new strains, most still diploid, homozygous for some or all of the markers and therefore associating or recombining in all possible ways the properties of the two strains from which the diploid was formed. Genetic recombination has thus been achieved in a filamentous fungus without a normal sexual cycle. Imperfect fungi are now open to genetic investigation. Deliberate ‘breeding’ of strains has become a practical proposition in industrial fermentations based on these fungi.

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.
