UV light induced accumulation of variability in a diploid strain of Aspergillus nidulans

A Marini, Sergio Pimpinelli, Nabil Matmati, Nora Babudri, Giorgio Oscar Morpurgo

Abstract

The accumulated variability in asexual species was evaluated in Aspergillus nidulans diploid cells after repeated cycles of UV irradiation. The results show that diploid cells can accumulate a very high genetic variability in the heterozygous condition as previously shown with the base analog 6-N-hydroxylaminopurine (HAP).
