[Formation of the respiratory enzyme apparatus in growing cells. IV. Composition of mitochondrial proteins synthesized in developing and germinating corn seeds].
The mitochondriogenesis in the developing maize embryo involves the accumulation of organelles with the relatively reduced matrix antigen content and relatively abundant several detergent-soluble membrane components, as compared with the mitochondria from differentiated root cells. Several new antigens are incorporated into the mitochondria of embryonic axes and scutella of imbibing seeds. While the qualitative protein patterns are constant, the ratio of individual antigens changes during the subsequent differentiation of root and scutellum cells. At the same time similar spectra consisting of 18--20 groups of mitochondrial polypeptides with the molecular weight from less than 12,000 to 115,000 are synthesized but the ratio of individual polypeptide groups changes differentially.
