✦ Synopsis

The levels of different classes of mitochondrially encoded transcripts are decelopmentally regulated in sea urchin embryos, as a result of selection between mutually exclusive synthetic pathways. Z propose a simple model to explain these observations, based on a dual role for mitochondrial ribosomes and translation factors in RNA synthesis as well as in translation. This effect may be exerted either at the transcriptional or posttranscriptional level (or both), and is potentially generalizable to mammalian mtDNA and to other systems.

We have isolated cold-resistant revertants from a mitochondrial cold-sensitive mutation, cs909, localized in the 21S ribosomal RNA gene. Two types of revertants have been isolated: (1) strong revertants which were shown to be due to a single, nuclear, dominant suppressor; (2) weak revertants which a
