“…Mitochondrial DNAs (mtDNAs) or their encoded proteins have been applied to investigations of the origin and evolution of eukaryotic species and the identification of biological germplasm resources (Derelle and Lang, 2012;Wu et al, 2015;Tan et al, 2016). They also have become important in anthropology (Pilipenko et al, 2017), bioarchaeology (Rusu and Kelemen, 2014), biotechnology (Hafez and Hausner, 2012), forensics (Liu and Harbison, 2017), medical studies (Sahota et al, 2016), plant pathology (Bertrand, 2000), taxonomy (van de Sande, 2012) and so forth.…”

Summary Isaria cicadae is an entomogenous fungus of great medicinal value. Its nuclear genome has been reported, while its mitogenome remains unknown. Herein, we first described its mitogenome and then inferred intron evolution from both intraspecific and interspecific perspectives. The fungus represented the largest mitogenome (56.6 kb in strain CCAD02) known in Cordycipitaceae due to the presence of 25 introns interrupting nine genes. Comparison of three I. cicadae strains revealed intron presence/absence dynamics at six intron loci plus a few indels and single nucleotide polymorphisms. Phylogenetic analyses confirmed the placement of I. cicadae in Cordycipitaceae. Comparison of 10 Cordycipitaceae species revealed a high degree of synteny and conserved genetic content. They, however, varied in intron numbers (1–25 per species) with overall 34 intron loci identified, which resulted in more than twofold variations in mitogenome sizes (24.5–56.6 kb). An rnl intron encoding ribosomal protein S3 was present in all species, suggesting its early invasion in Cordycipitaceae, while further divergence occurred for this intron. The other introns identified in this study were present in some, but not all of the species and have undergone multiple gains and losses in Cordycipitaceae. This study greatly enhanced our understanding of intron evolution in Cordycipitaceae.

“…We observed the greatest similarity (low F ST and close positions on the MDS plot) between our overall Tagar series and Scythians from the North Pontic region [ 3 , 4 , 26 ], followed by Scythian-period groups, including the South Siberia–Pazyryk population from the Altai Mountains and the Aldy-Bel population from Tuva (Russian Federation) [ 4 ]. Iron Age nomadic groups from the eastern part of the Eurasian steppe belt, such as Xiongnu [ 12 , 37 , 38 ] and Donghu [ 40 ], are highly differentiated with respect to the mtDNA pool structure from the Tagar and from other groups of the “Scythian World.”…”

“…Paleogenetic study of the anthropological remains of early nomads is one of the most promising areas of research at the moment. Analyses of the genetic composition of both eastern [ 1 , 2 , 12 , 37 , 38 ] and western [ 3 , 26 ] groups of early nomads of the Scythian and Xiongnu-Sarmatian epoch as well as the comparative analysis of early nomads from different regions [ 4 ] have been published. However, only a small series of individuals have been investigated for most early nomadic populations, even at the level of mitochondrial DNA, with the exception of the Pazyryk culture from the Altai Mountains (Scythian time) and Xiongnu, for which fairly representative mtDNA samples have been published.…”

Maternal genetic features of the Iron Age Tagar population from Southern Siberia (1st millennium BC)

Early nomads in the Eurasian steppes since the beginning of the 1st millennium BC played a key role in the formation of the cultural and genetic landscape of populations of a significant part of Eurasia, from Eastern Europe to Eastern Central Asia. Numerous archaeological cultures associated with early nomads have been discovered throughout the Eurasian steppe belt. The Tagar archaeological culture existed in the Minusinsk basin (Sayan Mountains, Southern Siberia, Russia) in the northeastern periphery of the Eurasian steppe belt from the 8th to 1st century BC during the pre-Scythian, Scythian, and Early Xiongnu-Sarmatian periods. In this study, we evaluated mtDNA diversity in the Tagar population based on representative series (N = 79) belonging to all chronological stages of the culture. The Tagar population had a mixed mtDNA pool dominated by Western Eurasian haplogroups and subgroups (H, HV6, HV*, I, K, T, U2e, U4, U5a, and U*) and, to a lesser degree, Eastern Eurasian haplogroups (A*, A8, C*, C5, D, G2a, and F1b). The Tagar population showed a similar mtDNA pool structure to those of other Iron Age populations representing the “Scythian World.” We observed particularly high similarity between the Tagar and Classic Scythians from the North Pontic region. Our results support the assumption that genetic components introduced by Bronze Age migrants from Western Eurasia contributed to the formation of the genetic composition of Scythian period populations in Southern Siberia. Another important component of the Tagar mtDNA pool was autochthonous East Eurasian lineages, some of which (A8 and C4a2a) are potential markers of the westward genetic influence of the eastern populations of the Scythian period. Our results suggest a genetic continuity (at least partial) between the Early, Middle, and Late Tagar populations.

Prehistoric Mongolian Archaeology in the Early 21st Century: Developments in the Steppe and Beyond

There has been a great increase in archaeological research in Mongolia since 2000. Increasingly precise chronologies, regional studies, and the growth of development-driven archaeology are transforming our knowledge of this key region of northeastern Asia. This review summarizes recent work and provides a narrative of the prehistoric and medieval cultural sequences as presently understood. I focus on long-standing key topics: early human habitation, the adoption of food-producing economies, Bronze Age social transformations, and the emergence of central places and large polities. I argue that, on the one hand, Mongolia has unique data and new examples to offer the archaeological community and, on the other, that the prehistory of Mongolia and the steppe are not so different from the rest of the world in its history of research and key questions. This review provides general overviews covering the Upper Paleolithic, Epipaleolithic or Neolithic, and Bronze Age to the Xiongnu period; specific data related to each period provide jumping-off points for comparative analysis and further examination.
