RESUMEN
The woolly mammoth mitochondrial genome (including the Malolyakhovsky mammoth) has been previously sequenced, followed by the annotation of all its genes (MF770243). In this study, based on the Malolyakhovsky mammoth, we describe for the first time the sites of functional significance in the control region of the woolly mammoth mitogenome.

Fragments of genomic DNA of Scots pine (Pinus sylvestris L.) homologous to the mitochondrial DNA (mtDNA) contigs of Norway spruce (Picea abies (L.) Karst.) and loblolly pine (Pinus taeda L.) were resequenced in a sample of the Scots pine trees of European, Siberian, Mongolian and Caucasian origin in order to develop mtDNA markers. Flanking non-coding regions of some mitochondrial genes were also investigated and resequenced. Five single nucleotide polymorphisms (SNPs) and a single minisatellite locus were identified. Caucasian samples differed from the rest by three SNPs. Two SNPs have been linked to an early described marker in.the first intron of the nad7 gene, and all together revealed three haplotypes in European populations. No variable SNPs were found in the Siberian and Mongolian populations. The minisatellite locus contained 41 alleles across European, Siberian and Mongolian populations, but, this locus demonstrated a weak population differentiation (F(ST) = 0.058), probably due to its high mutation rate.
