The ciliates and the cytoplasm
Department of Genetics and Development, University of Illinois Urbana IL 61801
Abstract
Cillate genetics is described as rising to a peak of public interest by the early 1950's. That interest is attributed in part to the use of microbial technology, but more significantly to the several examples of cytoplasmic inheritance in Parameclum described by Sonneborn and his associates. A subsequent falling off of interest in ciliate genetics is interpreted in part as a consequence of the success of alternative microbial tools. Also of significance in the decline was the resolution of the apparent conflict between nuclear and cytoplasmic heredity. The increasing understanding of the molecular basis of heredity, obtained mainly through bacterial studies, and the detailed analysis of the ciliate examples, showed that no fundamental distinctions separate nuclear and cytoplasmic heredity. Although cytoplasmic heredity no longer possesses the earlier mystique, many of the phenomena have not yet been explained in detail and merit further study. Moreover, the genetic domestication of the cillates achieved over recent decades now enables them to be used as instruments of analysis for a variety of eukaryotic properties.
