Abstract
New universal primers are offered for amplification of complete sequence of mitochondrial cyt b gene in lantern fishes of the family Myctophidae. Analysis of cyt b variability in the species of seven genera (Bolinichthys, Ceratoscopelus, Diaphus, Diogenichthys, Lampanyctus, Lepidophanes, Nannobrachium) demonstrates considerable divergence between species: an average of 18.2% (p-distances). Diversity (nucleotide diversity, number of segregating and phylogenetically informative sites, average number of nucleotide differences) and divergence significantly exceed those of another widely used mitochondrial marker, a fragment of cytochrome c oxidase subunit 1 sequence (cox 1). The mitochondrial cyt b gene amplified with the developed primers can be recommended as an informative tool for phylogenetic and population studies of lantern fishes.
