[Variation of ultrastructural organization of the mitochondria of pea cells in vitro].
Unusual huge organelles together with mitochondria of typical organization were found in a part of population of callus cells of pea. They like mitochondria are surrounded by two biologic membranes, the inner one has invaginations. Inclusions in the matrix are a specific character of structural organization of these unusual mitochondria. These inclusions look as electronically dense bars that extend parallel to longitudinal axis of organelle and consist of fibril-like elements. Organization of inclusions and cristae as well as a shape of organelles are changing during cell development. Possible nature of the unusual mitochondria is discussed.
