Kazakhstan is the center where Bactrians and Dromedaries can be raised, and hybridization between them has become widespread. Genetic resources of interspecies camel hybrids, raised in Kazakhstan, are represented by 30 generations.The most highly valuable in the conditions of Central Asia and Kazakhstan are transboundary camel breeds such as Kazakh Bactrian, Turkmen and Kazakh Dromedary, as well as new generations of camels Arada, Bainar and Baitur.At pure breeding of Kazakh Bactrian, genetic peculiarities are not taken into account, in view of the poor knowledge of this issue. To maintain the biodiversity, molecular genetic monitoring of the state of camel populations is required. Cytogenetic monitoring and certification are one of the promising areas for reliable camel genome assessment.Deep determination of Kazakh dairy camelsallele poolwas not carried out in Kazakhstan before. Genetic studies to optimize structure, identification and certification of valuable genotypes, as well as systematization of genetic resources in dairy camel breeding in Kazakhstan are urgent task.The aim of the study is identification, systematization and certification of genetic resources of Bactrian and Dromedary camels of Kazakh population using DNA technology. Genetic analysis of the typing results of the camels studied was carried out by 7 and 8 loci of DNA microsatellites. The material for the studies was DNA samples isolated from histological samples. The microsatellite loci were selected in accordance with the recommendations of the European Society of Genetics (FAO/ISAG).Identification and certification of Arvan and Kazakh Bactrian camels’ genetic resources using the microsatellite analysis of their genotype was carried outfor the first time. Breeding significance of Bactrian and Arvan camels of Kazakh population using DNA technologies was studied and determined. The obtained results of the study allowed evaluate camels at the level of the allelic profile.

Chironomus sokolovae Istomina, Kiknadze et Siirin, 1999 (Diptera, Chironomidae) is recorded from Mongolia for the first time. Eleven banding sequences determined in the Mongolian population were previously known from Altai and Yenisei populations: sokA1, sokB1, sokB2, sokC1, sokC2, sokD1, sokD2, sokE1, sokF1, sokF2 and sokG1. The additional B-chromosomes are absent. DNA-barcoding of COI gene was carried out for this species for the first time. The phylogenetic tree estimated by Bayesian inference showed a high similarity of the studied species with Ch. acutiventris Wülker, Ryser et Scholl, 1983 from the Chironomus obtusidens-group. The estimated genetic distance K2P between Ch. sokolovae and Ch. acutiventris is much lower (0.38%) than the commonly accepted threshold of 3% for species of genus Chironomus Meigen, 1803. Our results show that the accepted cytogenetic criteria of species level in the genus Chironomus are more in accordance with morphological ones of the same level, than with molecular-genetic criteria accepted for species COI genetic distance.

An early-branched moss Polytrichum commune is a widely accepted model object for ecological, environmental, physiological, and genetic studies. Its mitochondrial genome has been sequenced and annotated. The genome contains 67 genes in total and has a length equal to 114,831 bp, which exceeds the length of most known mitochondrial genomes for mosses. A phylogenetic tree based on 33 coding sequences of mitochondrial genome was constructed, and the pairwise identity of whole mitogenome sequences was estimated for 44 Bryophyta species. Based on the analysis of pairwise identity, it was shown that mitogenomes of Tetraphis pellucida and Buxbaumia aphylla sufficiently differ from those of other Bryophyta species. The first known Bryophyta mitogenome rearrangement was identified in Pogonatum inflexum within Polytrichopsida. Based on the intergenic repeats occurrence in 44 bryophyte mitochondrial genomes and available data on repetitive elements content in other Viridiplantae groups, it was noted for the first time that greater stability of the moss’s mitogenomes is probably associated mainly with the absence of long (>1 kb) repeats. The phenomenon of absence of the intergenic repetitive elements in the terminal clades species was discovered.

Abstract Considering the high importance of leek as a vegetable crop, this species is rarely an object of molecular genetic studies. In this study, SRAP and ISSR markers were used for the first time to investigate the genetic diversity in Turkish leek accessions together with some morphological characters. The study was conducted in Erciyes University Faculty of Agriculture in 2018–2020. Thirty-seven local varieties were collected from different towns in Turkey. Also, nineteen leek accessions, which originated from different regions of Turkey, had been kindly obtained from Plant Gene Banks, USDA. Seventeen SRAP and three ISSR markers were screened; all of them exposing 137 reproducible bands, of which 114 resulted in polymorphic. Polymorphism information content (PIC) varied between 0.209 and 0.840. Genetic similarities varied from 0.563 to 0.960, with an average of 0.789. In addition to molecular markers, the entire gene pool was morphologically characterized over two-year data. For this purpose, eight characters, which play a key role in leek breeding, were measured. At the end of the study, the analyzes made according to the molecular and morphological data were compared both separately and in combination. In all groupings, it was found remarkable that the accessions numbered 98*3, 40*1, 40*4, and 40*6 were positioned differently from the others. These results have provided important insights into the genetic variability of Turkish leek accessions for the first time. Also, the diversity analysis performed in this study provides valuable information to researchers for future studies.

The article describes the process of tench growing (male and female species removed from set gear in the Volga river in the Astrakhan region) using experimental feedstuff "T", taking into account the fact that problems with artificial growing tench ( Тinca tinca ) appear first in the process of feeding when wild sires change to artificial food. The research took place on the base of the department of aquaculture and water bioresources of Astrakhan State Technical University in innovation centre "Bioaquapark - scientific and technical centre of aquaculture" in 2015. Special feed including components of animal origin - mosquito grab and sludge worm as an effective substitute to fish flour, as well as components of vegetable origin (carrot, parsley, pumpkin, wheatgrass) for domestication of tenches are offered for the first time. Food technology has been described. The exact composition of the formula, which is being licensed at the moment, is not disclosed. Feed "T", which has undergone biological analysis and is in accordance with organoleptic and physical standards was used for feeding tench female and male species during domestication period (60 days), along with food "Coppens" (Holland). Feed efficiency was determined according to survival and daily fish growth. Growth rate of females appeared more intensive than growth rate of males fed with experimental food "T". Daily growth changed depending on the types of food: from 0.3 ("Coppens") to 0.47 (experimental food) in females, from 0.25 ("Coppens") to 0.39 (experimental food) with males. Ability to survive among tench species fed with "Coppens" and experimental food made 60% and 100%, correspondingly. Nutricion of tench species with experimental food encouraged their domestication, which allowed using tench species in further fish breeding process in order to get offspring. The project was supported by the Innovation Promotion Fund in terms of the project "Development and implementation of the technique for the steady development of aquaculture: food "TechSA".

The Stranger

Study abroad begins long before students leave their own shores. The moment that children enter daycare, nursery school, or kindergarten for the first time, they are in foreign territory, and all their antennae are out, testing, absorbing, learning. They begin to develop the first of their many multiple identities. They are no longer "Johnny" or "Sarah" whom everyone knows and loves at home, but Johnny or Sarah whom no one knows nor initially cares about, and they have to figure out what kind of a new identity they will develop so the danger zone becomes as safe as home.  Leaving familiar surroundings- the sounds, smells, safety, and food of home- and realizing, quite abruptly, that they must learn to adapt to the demands and needs of strangers, is the first and the most challenging "trip abroad" they will ever take. They will use the same set of skills, more mature, more polished (we hope) when they arrive on a foreign campus and move in with a host family or into an international dormitory.  Learning to make the journey with ease, whether it is on the first day of school or the day a plane drops one in a foreign field, is a necessary accomplishment. We have to make friends out of our peers; we have to gain the respect of our teachers; we have to develop curiosity and concern about the people around us. The stranger they seem, the more there is to learn. To fear diversity is to fear life itself. As the world becomes smaller and more integrated, the more crucial this accomplishment grows.
