Abstract:
A study of callase activity in relation to cytogenetical expressions in cytoplasmic male sterile and male fertile Petunia indicated differential timing of the localized enzyme activity. Enzyme activity was determined by a new test. The possible relations between the mode of action of the extrachromosomal gene, timing of the enzyme activity, and male sterility are discussed. © 1969 Plenum Publishing Corporation.
