W eier , T. E. (U. California, Davis.) Changes in the fine structure of chloroplasts and mitochondria during phylogenetic and ontogenetic development. Amer. Jour. Bot. 50(6):604–611. Illus. 1963.—“There are few of the cytoplasmic formed bodies that have not been supposed to bo the products of mitochondria; but few of these conclusions have not been contradicted by other observers.” Thus E. B. Wilson wrote in 1925. Were he on the scene today, his comment might be broader in scope, for the literature of fine structure is already replete with hypotheses transforming one organelle into another, largely on the basis of 2‐dimensional static profiles and with scant regard for genetical or biochemical consequences. And but few of these transformations have not been questioned by other observers. The aim of this review is to bring together some of these reports on transformations as they relate to plastids and mitochondria, to point out some of the biochemical consequences, and to suggest an approach to plant cellular biology involving a combination of comparative ultrastructure and comparative biochemistry which, it is hoped, might avoid the development of the impasse at the ultrastructural level into which the light microscopists of a half‐century ago worked themselves.
