Mutants

Description:

This strain was recovered from a cross between R107-4D mt+ and "wild-type" mt-. It has been maintained with acetate medium in darkness since its isolation. The R107-4D photosynthesis-competent revertant was selected from the Rubisco rbcL-mRNA deficient 76-5EN nuclear mutant. When R107-4D mt+ was crossed with "wild-type" mt-, tetrad analysis indicated that R107-4D resulted from a nuclear-gene intergenic-suppressor mutation (S107-4D). Thus, S107-4D suppresses 76-5EN by restoring Rubisco holoenzyme expression.
