Artemia mitochondrial genome: molecular biology and evolutive considerations.
During the last two decades an increasing amount of information has been accumulated regarding the gene structure and organization of the mitochondrial genome from various organisms. Many studies carried out mainly in mammals, have contributed to the knowledge of the basic elements involved in the replication and transcription of mitochondrial DNA. However, very little is known about these processes in invertebrates. In this review we discuss our current knowledge of the animal mitochondrial genetic system and briefly summarize the structure of the Artemia mitochondrial genome, the characteristics of its transcriptional machinery and how its expression is controlled during early development, in relation with what is known in other organisms. Artemia is the only crustacean where the mtDNA has been studied at this level of detail up to date.
