Mitogenomic phylogeny and divergence time estimation of Artemia Leach, 1819 (Branchiopoda: Anostraca) with emphasis on parthenogenetic lineages.

ABSTRACT: The brine shrimp Artemia, a crustacean adapted to the extreme conditions of hypersaline environments, comprises nine regionally distributed sexual species scattered (island-like) over heterogeneous environments and asexual (parthenogenetic) lineages with different ploidies. Such sexual and asexual interaction within the genus raises questions regarding the origin and time of divergence of both sexual species and asexual lineages, including the persistence of the latter over time, a problem not yet clarified using single mitochondrial and nuclear markers. Based on the complete mitochondrial genome of all species and parthenogenetic lineages, this article first describes the mitogenomic characteristics (nucleotide compositions, genome mapping, codon usage, and tRNA secondary structure) of se
