Novel peroxisome clustering mutants and peroxisome biogenesis mutants of Saccharomyces cerevisiae

A positive selection method which uses the toxicity of hydrogen peroxide facilitates the detection of peb complementation groups in Saccharomyces cerevisiae. The new mutants which are detected are devoid of peroxisomes or peroxisomal function. Four complementation groups of peroxisome biogenesis mutants are detected.
