The Oenothera plastome mutator: effect of UV irradiation and nitroso-methyl urea on mutation frequencies.
Molecular & general genetics : MGG - 1 Oct 1991
Sears B B, Sokalski M B
Abstract excerpt
Oenothera plants homozygous for a recessive plastome mutator allele (pm) showed spontaneous mutation frequencies for plastome genes that are 200-fold higher than spontaneous levels. Mutations occurred at high frequencies in plants grown in the field, in a glasshouse, or as leaf tip cultures under fluorescent light, indicating that the plastome mutator activity is UV-independent. However, the chlorotic sectors...
