The mitochondrion is the organelle within the eukaryotic cell that is primarily concerned with the synthesis of ATP in respiration. Current hypothesis traces it origins to an endosymbiotic event to form a cell lineage containing two independent genomes. Full comprehension of the mitochondrial (mt) genome structure is of fundamental importance not only for it evolutionary implications but also for a better understanding of biochemical processes that take place into this organelle in crop model species. Several mt genome sequences have been recently released from higher plants. We present here the tomato mitochondrial genome and a web-interface resource for plant mitochondrial comparative genomics.
