The Suppression of AD-3B Mutants by Supersuppressors in NEUROSPORA CRASSA
AUTOR(ES)
Newcombe, K. D.
RESUMO
The action of eight suppersuppressors has been tested on 76 ad-3B mutants which were induced by base-pair transition mutagens. Thirteen mutants were found to be suppressible by at least one ssu gene. Most of the suppressible mutants were found to belong to a class in which one would expect to find nonsense mutants (polar complementing or noncomplementing classes, with AT at the mutant site). However, suppression was observed in other classes, including those containing presumed missense mutants. The specificity of the suppressors and the criteria for molecular classification of the mutants are discussed.
