Genomics of Ancient Pathogens: First Advances and Prospects.

Paleogenomics is one of the urgent and promising areas of interdisciplinary research in the today's world science. New genomic methods of ancient DNA (aDNA) analysis, such as next generation sequencing (NGS) technologies, make it possible not only to obtain detailed genetic information about historical and prehistoric human populations, but also to study individual microbial and viral pathogens and microbiomes from different ancient and historical objects. Studies of aDNA of pathogens by reconstructing their genomes have so far yielded complete sequences of the ancient pathogens that played significant role in the history of the world: Yersinia pestis (plague), Variola virus (smallpox), Vibrio cholerae (cholera), HBV (hepatitis B virus), as well as the equally important endemic human infectious agents: Mycobacterium tuberculosis (tuberculosis), Mycobacterium leprae (leprosy), and Treponema pallidum (syphilis).

Data on the genome analysis of the wood-rotting fungus LE-BIN 3174.

In the present article, we report data on the whole-genome sequencing of wood-rotting (white-rot) fungus LE-BIN 3174. The LE-BIN 3174 genome consists of 770 scaffolds (N50 = 62,812 bp) with the total length of assembly ∼35 Mb. The structural annotation of the genome resulted in the prediction of 12,441 gene models, among which 181 were models of tRNA-coding genes, and 12,260 - protein-coding genes.

Fungal Adaptation to the Advanced Stages of Wood Decomposition: Insights from the .

is a white rot basidiomycete with wide ecological amplitude. It occurs in different regions of Russia and throughout the world, occupying different climatic zones. colonizes stumps, trunks, and branches of various deciduous (seldom coniferous) trees.

Biotransformation of progesterone by Aspergillus nidulans VKPM F-1069 (wild type).

Biotechnological transformation of steroids using enzyme systems of microorganisms is often the only possible method to modify the molecule in the industrial production of steroid drugs. Filamentous fungus Aspergillus nidulans has been little studied as a steroid-transforming microorganism. We studied the ability of the A.

Evolutionary Relationships Between the Laccase Genes of Polyporales: Orthology-Based Classification of Laccase Isozymes and Functional Insight From .

Laccase is one of the oldest known and intensively studied fungal enzymes capable of oxidizing recalcitrant lignin-resembling phenolic compounds. It is currently well established that fungal genomes almost always contain several non-allelic copies of laccase genes (laccase multigene families); nevertheless, many aspects of laccase multigenicity, for example, their precise biological functions or evolutionary relationships, are mostly unknown. Here, we present a detailed evolutionary analysis of the laccase genes (CAZy - AA1_1) from fungi of the Polyporales order.

Orchestration of the expression of the laccase multigene family in white-rot basidiomycete Trametes hirsuta 072: Evidences of transcription level subfunctionalization.

Laccase (benzenediol:oxygen oxidoreductase, EC 1.10.3.

Properties of two laccases from the Trametes hirsuta 072 multigene family: Twins with different faces.

Utilization of laccases in biotechnology and bioremediation has created a strong demand for the characterization of new enzymes and an increase in production of known laccases. Thus, additional research into these enzymes is critically needed. In this study, we report a comparative study of the biochemical and transcriptional properties of two different laccase isozymes from Trametes hirsuta 072 - the constitutive and inducible forms.

Lignin-degrading peroxidases in white-rot fungus Trametes hirsuta 072. Absolute expression quantification of full multigene family.

Ligninolytic heme peroxidases comprise an extensive family of enzymes, which production is characteristic for white-rot Basidiomycota. The majority of fungal heme peroxidases are encoded by multigene families that differentially express closely related proteins. Currently, there were very few attempts to characterize the complete multigene family of heme peroxidases in a single fungus.

Laccase multigene families in Agaricomycetes.

Here we present the results of the exploration of laccase multigene families (MGFs) in basidiomycetous fungi from different taxonomic groups using a next generation sequencing (NGS) technology. In our study, multiple laccase genes were identified in all of the investigated fungi (13 species) from Polyporaceae, Phanerochaetaceae, Meruliaceae, Pleurotaceae, Physalacriaceae, and Peniophoraceae families. It was shown that phylogenetic positioning of the newly identified sequences exhibit patterns of clusterization with respect to enzyme properties.

Draft Genome Sequence of the Fungus Trametes hirsuta 072.

A standard draft genome sequence of the white rot saprotrophic fungus Trametes hirsuta 072 (Basidiomycota, Polyporales) is presented. The genome sequence contains about 33.6 Mb assembled in 141 scaffolds with a G+C content of ~57.

Whole-genome sequencing identifies a novel ABCB7 gene mutation for X-linked congenital cerebellar ataxia in a large family of Mongolian ancestry.

X-linked congenital cerebellar ataxia is a heterogeneous nonprogressive neurodevelopmental disorder with onset in early childhood. We searched for a genetic cause of this condition, previously reported in a Buryat pedigree of Mongolian ancestry from southeastern Russia. Using whole-genome sequencing on Illumina HiSeq 2000 platform, we found a missense mutation in the ABCB7 (ABC-binding cassette transporter B7) gene, encoding a mitochondrial transporter, involved in heme synthesis and previously associated with sideroblastic anemia and ataxia.

The Trametes hirsuta 072 laccase multigene family: Genes identification and transcriptional analysis under copper ions induction.

Laccases, blue copper-containing oxidases, ≿ an play an important role in a variety of natural processes. The majority of fungal laccases are encoded by multigene families that express closely related proteins with distinct functions. Currently, only the properties of major gene products of the fungal laccase families have been described.

Genetic variability of 15 autosomal STR loci in Russian populations.

Allele frequencies for 15 STRs (CSF1PO, D3S1358, D5S818, D7S820, D8S1179, D13S317, D16S539, D18S51, D21S11, FGA, Penta D, Penta E, THO1, TPOX, and vWA) in the PowerPlex 16 System (Promega Corporation) were assessed in 386 individuals from five Russian urban populations. No significant between-population differences in frequencies and molecular variance of 15 microsatellites were revealed. For all 15 loci, the combined matching probability is 3.

In silico search for natural antisense transcripts reveals their differential expression in human tumors.

We created an algorithm that allows high-throughput mapping of sense-antisense (SA) pairs of transcripts. By this method we mapped approximately 32 000 SA pairs of human mRNAs. Collected SA pairs were divided into three groups: SA pairs based on two or more UniGene clusters (17% of all sense-antisense pairs), SA pairs based on ESTs that belong to the same UniGene cluster (42%), and SA pairs formed by UniGene cluster and non-unique unclustered transcripts (41%).

Distinct organization of the candidate tumor suppressor gene RFP2 in human and mouse: multiple mRNA isoforms in both species- and human-specific antisense transcript RFP2OS.

In the present study, we describe the human and mouse RFP2 gene structure, multiple RFP2 mRNA isoforms in the two species that have different 5' UTRs and a human-specific antisense transcript RFP2OS. Since the human RFP2 5' UTR is not conserved in mouse, these findings might indicate a different regulation of RFP2 in the two species. The predicted human and mouse RFP2 proteins are shown to contain a tripartite RING finger-B-box-coiled-coil domain (RBCC), also known as a TRIM domain, and therefore belong to a subgroup of RING finger proteins that are often involved in developmental and tumorigenic processes.
