Conidia Of Aspergillus Nidulans Research Articles

UV-INDUCED MITOTIC RECOMBINATION IN THE PABA-1 REGION AF ASPERGILLUS NIDULANS.

UV irradiation of diploid conidia ofAspergillus nidulans induces mitotic recombination within thepaba1 region. The frequency of this UV-induced intragenic recombination is enhanced if a short period of incubation in a non-selective medium precedes plating of irradiated conidia in a selective medium.

Radiation-induced chromosomal aberrations and lethals in Aspergillus nidulans.

The frequency of translocations induced in diploid conidia of Aspergillus nidulans by gamma rays was much higher than that of recessive mutants involving a single chromosome. More than half of the surviving nuclei contained viable translocations at radiation doses within the range normally employed for induction of mutants in microorganisms.
