Resumen:
South American camelids comprise the guanaco (Lama guanicoe) and the vicuña (Vicugna vicugna),which are wild species, and the domestic llama (Lama glama) and alpaca (Lama pacos). This paperpresents the first complete mitochondrial (mt) genome of the guanaco and the mt coding sequence ofthe vicuña. The guanaco mtDNA is 16,649 nt long and its composition and organization are similarto the mitochondrial genome of other mammals. Excluding the control region, comparison of thecomplete guanaco and vicuña mtDNA showed 4.4% sequence divergence. Nucleotide differences inpeptide coding genes varied from 1.9% in ATP6 to 6.4% in Cyt b. These values are compatible withthe close relatedness of both species identified by other authors. Based on the differences betweenthe control region sequence here reported and that previously described, we also discuss theoccurrence of NUMTs in the genome of South American camelids.Lama guanicoe) and the vicuña (Vicugna vicugna),which are wild species, and the domestic llama (Lama glama) and alpaca (Lama pacos).
