Mutants

Description:

This strain was recovered from a cross between R118-1E mt+ and "wild-type" mt-. It has been maintained with acetate medium in darkness since its isolation. The R118-1E photosynthesis-competent revertant was selected from the Rubisco rbcL-mRNA deficient 76-5EN nuclear mutant. When R118-1E mt+ was crossed with "wild-type" mt-, tetrad analysis indicated that R118-1E resulted from a nuclear-gene intergenic-suppressor mutation (S118-1E). Thus, S118-1E suppresses 76-5EN by restoring Rubisco holoenzyme expression.
