Abstract

Exposure of autotrophic cells ofEuglena gracilis to MNNG and furazolidone results in an irreversible loss of chloroplasts leading to a production of white mutants (permanent bleaching). Induction of the white mutants is significantly decreased by ascorbic acid, especially during the first stages of this mutation process.
