The authors investigated the allele microsatellite locus Ma-3 composition in the Middle Amur Region sable (Martes zibellina). Three subpopulations of animals from the Bureinsky Highlands (Magan, Sutyr and Kamenushka), as well as one from the western macro slope of the Sikhote-Alin ridge (Manoma) were analyzed. The genetic material was collected for the hunting seasons of 2011/2012 – 2017/2018. Subpopulations of the northern (Magan) and middle (Sutyr) parts of the Bureinsky ridge were most similar to each other in their allele composition In the subpopulation of the Bureinsky Highlands southern part (Kamenushka) some slight differences were found. In the Manoma subpopulation, the specific allele 129 was found in hunting catches of 2012-2013 and 2017-2018. The specific allele presence in this subpopulation has proved some geographic isolation between the Sikhote Alin and the Bureinsky Highlands sable populations.

Five new species of the family Poaceae are described from the Russian Far East: Agrostis czernjaginae Prob. (sect. Trichodium) (revealed chromosome number 2n = 42) from thermal springs of Kamchatka, Bromopsis kozhevnikovii Prob. (sect. Rhizomatosae) from high mountains of Dusse-Alin Range in the Khabarovsk Territory, Poa amurica Prob. (sect. Stenopoa) from Selemdzha River in the Amur Region, Koeleria dersu Prob. et Prokopenko (sect. Koeleria) from the eastern macroslope of Sikhote-Alin in the Primorye Territory, Agrostis × lapenkoi Prob. (probably, intersectional hybrid: A. giganteaRoth × A. clavata Trin.) from Ussuri River basin, also in the Primorye Territory.

Gold Bearing

The paper deals with the problem of assessing the gold content of pre-Quaternary weathering crusts, which are widespread in the foothills of the doming-block geomorphological structures of the Amur Region, Khabarovsk and Primorsky Territories, by framing large and medium-sized Cenozoic depressions and depressions. For a more detailed mining and geological study and assessment of the gold content of the weathering crusts, we recommended the Rybachy site as one of these objects (not fully studied), and the entire Mukhenskaya area as a promising one.

Tea (Camellia sinensis L. [O.] Kuntze) is a highly cross-pollinated and self-incompatible plant. Seeds can be harvested from specific individual mother plants in polyclonal tea gardens. Whether the pollen donor plays an important role in seed formation remains unclear. This study aimed to identify the male parents of 72 natural hybridized progenies (F1) from one female parent on the basis of a putative specific allele by using simple-sequence repeat (SSR) markers and the exclusion-likelihood method with Cervus 3.0 software. The genetic material, which comprised seven accessions of C. sinensis L., was acquired from Assamica planted in the Kayulandak polyclonal seed garden of the Pagilaran tea plantation in Batang District, Central Java, Indonesia, and was studied during 2019 and 2020. The genotype PGL-15 was used as the female parent, whereas the six candidate genotypes PGL-10, GMB-9, GMB-7, TPS-93, GMB-11, and TRI-2025 were used as the male parents. In this study, 13 SSR loci were used to identify the male parents of the F1 progenies obtained through natural hybridization between one female and six male tea accessions. Results indicated that the exclusion-likelihood method, which correctly predicted 100% of the male parents, was more effective than the putative specific allele approach, which correctly predicted only 34.72% of the male parents in the 72 hybridized F1 progenies of tea plants.

Human Infections

Seven zoonoses — human infections of animal origin — have emerged from the Coronaviridae family in the past century, including three viruses responsible for significant human mortality (SARS-CoV, MERS-CoV, and SARS-CoV-2) in the past twenty years alone. These three viruses, in addition to two older CoV zoonoses (HCoV-229E and HCoV-NL63) are believed to be originally derived from wild bat reservoir species. We review the molecular biology of the bat-derived Alpha- and Betacoronavirus genera, highlighting features that contribute to their potential for cross-species emergence, including the use of well-conserved mammalian host cell machinery for cell entry and a unique capacity for adaptation to novel host environments after host switching. The adaptive capacity of coronaviruses largely results from their large genomes, which reduce the risk of deleterious mutational errors and facilitate range-expanding recombination events by offering heightened redundancy in essential genetic material. Large CoV genomes are made possible by the unique proofreading capacity encoded for their RNA-dependent polymerase. We find that bat-borne SARS-related coronaviruses in the subgenus Sarbecovirus, the source clade for SARS-CoV and SARS-CoV-2, present a particularly poignant pandemic threat, due to the extraordinary viral genetic diversity represented among several sympatric species of their horseshoe bat hosts. To date, Sarbecovirus surveillance has been almost entirely restricted to China. More vigorous field research efforts tracking the circulation of Sarbecoviruses specifically and Betacoronaviruses more generally is needed across a broader global range if we are to avoid future repeats of the COVID-19 pandemic.
