Abstract

The control region of the mitochondrial genome was amplified and sequenced for six individuals of the gobioid fish Pomatoschistus minutus, from several European localities, and one specimen of the related Deltentosteus quadrimaculatus. The length of this region for the former species was found to be 773 bp, 7·1% shorter than that previously described as the most compact D-loop known among teleosts. Sequences from other fish have been compared and the largest gap falls in the section between the conserved sequence block and the pyrimidine tract. Alignment of P. minutus sequences was done with D. quadrimaculatus, whose control region length was 853 bp, and this gap was found to be of 61 bp. For the P. minutus sample, the intraspecific sequence divergence is 0·07%.
