  • Title: Mutagen sensitivity of Neurospora meiotic mutants.
    Author: Schroeder AL, Olson LD.
    Journal: Can J Genet Cytol; 1983 Feb; 25(1):16-25. PubMed ID: 6220799.
    Abstract:
    The Neurospora meiotic mutants, mei-1, mei-2, mei-3, and mei-4 were tested for cross sensitivity to mutagens. Mei-2 and mei-3 are sensitive to MMS, gamma-irradiation and histidine. Mei-2 is not sensitive to ultraviolet (UV) at 20 degrees C. Tests with recombinants with crossovers to either side of mei-2 or mei-3 show that these traits are the pleiotropic properties of a single gene which also determines meiotic behavior. The mei-2 gene maps to the right of al-3 on linkage group V. It is not allelic to mus-11. Upon backcrossing, the originally dominant meiotic effect of mei-2 becomes recessive to partially dominant. The histidine sensitivity is recessive.
