Cytoplasmic inheritance of chloroplast coupling factor 1 subunits

Abstract
An analysis of interspecific hybrids of Nicotiana spp. in which one of the parents was sensitive to tentoxin showed that this sensitivity was transmitted only through the female parent. Since tentoxin acts by selectively binding to the α,β subunit complex of chloroplast coupling factor 1, the gene(s) specifying either one or both of these subunits is located in the cytoplasm.
