The small nuclear genome of the pufferfish, Fugu rubripes (order Tetraodontiformes), makes this species highly interesting for genome research. In order to establish the phylogenetic position of the Tetraodontiformes relative to other teleostean orders that might also have a reduced nuclear genome size, we have sequenced the mitochondrial (mt) genome of the(More)
It is commonly accepted that among recent fishes the lungfishes are the closest relatives of the tetrapods. According to this hypothesis, the tetrapods, lungfishes and coelacanths constitute a group of specialized fishes (Sarcopterygii) to the exclusion of other bony fishes. Here, we describe basal relationships among gnathostome (jawed) vertebrates as(More)
