Brine shrimps, Artemia (Crustacea, Anostraca), inhabit hypersaline environments and have a broad geographical distribution from sea level to high plateaus. Artemia therefore possess significant genetic diversity, which gives them their outstanding adaptability. To understand this remarkable plasticity, we sequenced the mitochondrial genomes of two Artemia tibetiana isolates from the Tibetan Plateau in China and one Artemia urmiana isolate from Lake Urmia in Iran and compared them with the genome of a low-altitude Artemia, A. franciscana. We compared the ratio of the rate of nonsynonymous (Ka) and synonymous (Ks) substitutions (Ka/Ks ratio) in the mitochondrial protein-coding gene sequences and found that atp8 had the highest Ka/Ks ratios in comparisons of A. franciscana with either A. tibetiana or A. urmiana and that atp6 had the highest Ka/Ks ratio between A. tibetiana and A. urmiana. Atp6 may have experienced strong selective pressure for high-altitude adaptation because although A. tibetiana and A. urmiana are closely related they live at different altitudes. We identified two extended termination-associated sequences and three conserved sequence blocks in the D-loop region of the mitochondrial genomes. We propose that sequence variations in the D-loop region and in the subunits of the respiratory chain complexes independently or collectively contribute to the adaptation of Artemia to different altitudes. mitochondrial genome, Artemia tibetiana, sequence variation, high plateau species Citation:Zhang H X, Luo Q B, Sun J, et al.

Sci China Life Sci, 2013Sci, , 56: 440 -452, doi: 10.1007 Brine shrimps, Artemia (Crustacea, Anostraca), have a broad geographical distribution and inhabit hypersaline environments that vary considerably in their anionic composition, climate, and altitude. The major anions that contribute to anionic composition include chloride, sulfate, carbonate, or combinations of up to all three [1]. Artemia species can be found in altitudes from sea level to over 4000 m above sea level; for example, in Tibet (4000 m) and in the East African Plateau (over 5000 m). Artemia can survive in harsh environments other than in high salinity, including low atmospheric pressure, rarefied air, cold temperature, and long winters, as well as in climatological conditions that range from humid to arid [2]. Artemia species are capable of switching their reproduction strategies between sexual and parthenogenetic forms in a single life cycle [1,3,4], and populations can survive through cold winters by producing diapause cysts [5][6][7].

“…So far, the complete mitochondrial sequence and gene order have been obtained only in a few insect taxa, including Drosophila (Clary & Wblstenholme, 1985), Anopheles (Beard et al, 1993;Mitchell et al, 1993), Apis (Crazier & Crozier, 1993), and Locusta (Flook et al, 1995). The complete sequences of other arthropod species have been obtained in Artemia franciscana (Perez et al, 1994), and some chelicerates (Staton et al, 1997;Black & Roehrdanz, 1998;Campbell & Baker, 1999). A partial sequence of genes of the mitochondrial genome of G. hodgsoni (Hypogastruridae), encompassing the fragment comprised between the genes COI and ND5, is shown in Figure 7, together with the gene order of the corresponding fragment in other insect species.…”

The mitochondrial COII gene was shown to be a useful marker at the population level in Isotoma klovstadi, and for studying phylogenetic relationships at the family level, while the nuclear EF-lα and 28S rRNA genes were less useful. The populations of I. klovstadi from four collecting sites in North Victoria Land appeared to be fairly isolated from one another, with the exception of one population which has probably been influenced by immigrants from others. The position of Friesea grísea within the Neanuridae suggests that, in contrast with other morphological hypotheses, the subfamily Frieseinae is the sister-group of the Pseudachorutinae. Comparison of the mitochondrial gene order in Gomphiocephalus hodgsoni and other insects suggested that some translocations in the tRNA genes may represent useful markers for reconstructing phylogenetic relationships within Arthropoda.

“…Darwinulid ostracods also apparently comprise asexual lineages on the order of millions of years old (Chaplin et al 1994;Griffiths and Butlin 1995;Chaplin and Hebert 1997;Butlin et al 1998b;Schön et al 1998), although multiple transitions to asexuality by related sexuals (Chaplin and Hebert 1997) make robust interpretation of the ages of some lineages problematic. Phylogenetic or taxonomic evidence consistent with ancient asexuality can also be found among beetles (Lanteri and Normark 1995;Normark 1996), aphids (Simon et al 1996;Normark 1999;Blackman et al 2000), mites (Perrot-Minnot and Norton 1997), walkingsticks (Mantovani et al 2001), clams (Ó Foighil and Smith 1995), and brine shrimp (Perez et al 1994). However, in these cases various limitations, including incomplete sampling of extant asexuals and related sexuals (Little and Hebert 1996;Dufresne and Hebert 1997), rare sex (Hurst et al 1992;Turgeon and Hebert 1995;Belshaw et al 1999;Simon et al 1999), underestimation of the number of transitions to asexuality (Harshman and Futuyma 1985;Hugall et al 1994;Pongratz et al 1998;Johnson and Bragg 1999;Normark 1999;Delmotte et al 2001), and possible recent extinction of sexuals (Normark 1999), reduce the confidence with which truly ancient lack of sexuality can as yet be inferred.…”

Abstract. Determining the evolutionary age of asexual lineages should help in inferring the temporal scale under which asexuality and sex evolve and assessing selective factors involved in the evolution of asexuality. We used 416 bp of the mitochondrial COI gene to infer phylogenetic relationships of virtually all known Timema walkingstick species, including extensive intraspecific sampling for all five of the asexuals and their close sexual relatives. The asexuals T. douglasi and T. shepardii were very closely related to each other and evolutionarily young (less than 0.5 million years old). For the asexuals T. monikensis and T. tahoe, evidence for antiquity was weak since only one population of each was sampled, intraspecific divergences were low, and genetic distances to related sexuals were high: maximum-likelihood molecular-clock age estimates ranged from 0.26 to 2.39 million years in T. monikensis and from 0.29-1.06 million years in T. tahoe. By contrast, T. genevieve was inferred to be an ancient asexual, with an age of 0.81 to 1.42 million years. The main correlate of the age of asexual lineages was their geographic position, with younger asexuals being found further north.
