Non-Mendelian streptomycin-resistant tobacco mutant with altered chlorplasts and mitochondria.

Abstract

THE possibility of producing mutant plants of economic value by tissue culture techniques has attracted considerable interest and discussion1–6, and was confirmed by the regeneration of plants from mutant cell lines1. The isolation of cytoplasmic mutants (all of those studied so far have carried Mendelian traits1,2) can be of practical importance; for example, male sterile ones in maize may be used for producing hybrid seeds. We report here, however, properties of a non-Mendelian, cytoplasmic mutant.
