The population differentiation based on morphological traits was weak. Analysis of the essential oil composition provided the subdivision of the sample into three groups and, on the basis of the composition of ISSR amplicons, into four groups of specimens. A high degree of genetic polymorphism of M. arvensis and substantial, though incomplete, population differentiation were identified. It was demonstrated that the population of M. arvensis from the Komi Republic was the most genetically isolated, while the populations from Moscow and Penza provinces were weakly differentiated from each other. The population from the Republic of Belarus (near Grodno) was genetically and phytochemically considerably different from the other studied populations, although morphologically indistinguishable from them. We argue that the differentiation was caused not only by the isolation by distance but also owing to the formation of three different ecotypes adapted to different climatic conditions.","PeriodicalId":12707,"journal":{"name":"Genetika","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2017-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"35768428","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Pendred syndrome is one of the most frequent types of syndromic hearing loss. Hearing impairment is accompanied by abnormal development of the bony labyrinth—enlarged vestibular aqueduct (EVA) and occasionally combined with Mondini dysplasia. Mutations in the SLC26A4 gene, which encodes the pendrin protein, are responsible for both Pendred syndrome and for allelic disorder (nonsyndromic enlarged vestibular aqueduct). The present study for the first time conducted molecular genetic analysis in 20 Russian patients with Pendred syndrome, EVA and/or Mondini dysplasia. As a result, six pathogenic mutations in the SLC26A4 gene were revealed in four patients. The mutation c.222G>T (p.Trp74Cys) was detected for the first time. Mutations were found in patients with Pendred syndrome and nonsyndromic EVA with or without Mondini dysplasia. Mutations were not detected in patients with isolated Mondini dysplasia. One proband with clinical diagnosis Pendred syndrome was homozygous for the c.35delG mutation in the GJB2 gene. The absence of frequent mutations, including well-known ones or “hot” exons in the SLC26A4 gene, was reported. Therefore, the optimal method to search for mutations in the SLC26A4 gene in Russian patients is Sanger sequencing of all exons and exon-intron boundaries in the SLC26A4 gene.","PeriodicalId":12707,"journal":{"name":"Genetika","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2017-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"35768431","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The encoded proteins (heat shock proteins, Hsps) represent the most important factors of adaptation to adverse environmental conditions. They serve as molecular chaperones, providing protein folding and preventing aggregation of damaged cellular proteins. Structural analysis of the heat shock genes in individuals from both phylogenetically close and very distant taxa made it possible to reveal the basic trends of the heat shock gene organization in the context of adaptation to extreme conditions. Using different model objects and nonmodel species from natural populations, it was demonstrated that modulation of the Hsps expression during adaptation to different environmental conditions could be achieved by changing the number and structural organization of heat shock genes in the genome, as well as the structure of their promoters. It was demonstrated that thermotolerant species were usually characterized by elevated levels of Hsps under normal temperature or by the increase in the synthesis of these proteins in response to heat shock. Analysis of the heat shock genes in phylogenetically distant organisms is of great interest because, on one hand, it contributes to the understanding of the molecular mechanisms of evolution of adaptogenes and, on the other hand, sheds the light on the role of different Hsps families in the development of thermotolerance and the resistance to other stress factors.","PeriodicalId":12707,"journal":{"name":"Genetika","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2017-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"35768425","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
