Abstract

A study of the nucleotide sequencing and database analysis of the protein sequence of the region affecting metronidazole sensitivity in E. coli F19 reveals that it contains a regulator gene, regA, which has 40 percent identity to the ccpA gene of B. subtilis. The regA gene inhibited the expression of a C. acetobutylicum gene that allows the starch to degrade into acetone, butanol and ethanol. Analysis of the solvent-producing pathways and acid-producing pathways did not yield the cause of the molecular changes.

Abstract

Relevant for various areas of human genetics, Y-chromosomal STRs (Y-STRs) are commonly used for testing close paternal relationships amongst individuals and populations, and for male lineage identification. However, even the widely used 17-loci Yfiler set cannot resolve individuals and populations completely. Here, 52 centers generated quality-controlled data of 13 rapidly-mutating (RM) Y-STRs in 14,644 related and unrelated males from 111 worldwide populations. Strikingly, >99% of the 12,272 unrelated males were completely individualized. Haplotype diversity was extremely high (global: 0.9999985, regional: 0.99919-0.9999988). Haplotype sharing between populations was almost absent except for six (0.05%) of the 12,156 haplotypes. Haplotype sharing within populations was generally rare (0.8% non-unique haplotypes), significantly lower in urban (0.9%) than rural (2.1%) and highest in endogamous groups (14.3%). AMOVA revealed 99.98% of variation within populations, 0.018% among populations within groups, and 0.002% among groups. Of the 2,372 newly and 156 previously typed male relative pairs, 29% were differentiated including 27% of the 2,378 fathers/son pairs. Relative to Yfiler, haplotype diversity was increased in 86% of the populations tested and overall male relative differentiation was raised by 23.5%. Our study demonstrates the value of RM Y-STRs in identifying and separating unrelated and related males and provides a reference database.

Abstract

Background: Wild animals' meat is extensively consumed in South Africa, being obtained either from ranching, farming or hunting. To test the authenticity of the commercial labels of meat products in the local market, we obtained DNA sequence information from 146 samples (14 beef and 132 game labels) for barcoding cytochrome c oxidase subunit I and partial cytochrome b and mitochondrial fragments. The reliability of species assignments were evaluated using BLAST searches in GenBank, maximum likelihood phylogenetic analysis and the characterbased method implemented in BLOG. The Kimura-2-parameter intra- and interspecific variation was evaluated for all matched species. Results: The combined application of similarity, phylogenetic and character-based methods proved successful in species identification. Game meat samples showed 76.5% substitution, no beef samples were substituted. The substitutions showed a variety of domestic species (cattle, horse, pig, lamb), common game species in the market (kudu, gemsbok, ostrich, impala, springbok), uncommon species in the market (giraffe, waterbuck, bushbuck, duiker, mountain zebra) and extra-continental species (kangaroo). The mountain zebra Equus zebra is an International Union for Conservation of Nature (IUCN) red listed species. We also detected Damaliscus pygargus, which is composed of two subspecies with one listed by IUCN as 'near threatened'; however, these mitochondrial fragments were insufficient to distinguish between the subspecies. The genetic distance between African ungulate species often overlaps with within-species distance in cases of recent speciation events, and strong phylogeographic structure determines withinspecies distances that are similar to the commonly accepted distances between species. Conclusions: The reliability of commercial labeling of game meat in South Africa is very poor. The extensive substitution of wild game has important implications for conservation and commerce, and for the consumers making decisions on the basis of health, religious beliefs or personal choices. Distance would be a poor indicator for identification of African ungulates species. The efficiency of the character-based method is reliant upon availability of large reference data. The current higher availability of cytochrome b data would make this the marker of choice for African ungulates. The encountered problems of incomplete or erroneous information in databases are discussed. [ABSTRACT FROM AUTHOR]

35. Identification and Characterization of a Major Early-Transcribed Gene of Trichoplusia niSingle Nucleocapsid Nucleopolyhedrovirus Using the Baculovirus Expression System

Author

Wang, Weizhou, Davison, Sean, and Krell, Peter

Abstract

An early transcribed gene (me-53) of a South Africa strain of Trichoplusia nisingle nucleocapsid nucleopolyhedrovirus (TnSNPV) was sequenced and identified. It has an open reading frame of 1146 nucleotides that encodes a protein of 382 amino acids with a molecular mass of 45.2 kDa. The deduced protein sequence alignment of 13 baculovirus ME-53s indicated that the TnSNPV ME-53 shares the highest homologies with NPV subgroup II-A Spodoptera exiguamultiple and Mamestra configurata(Maco) nucleopolyhedrovirus ME-53s. The zinc finger-like motifs at the C-termini of ME-53s are highly conserved with similar patterns of cysteine positions. Upon introduction of the gene and a green fluorescent protein reporter gene into the baculovirus expression vector system, the transcriptional analysis of me-53in two cell lines infected with the Autographa californicanucleopolyhedrovirus (AcMNPV) recombinant revealed that an early TnSNPV me-53transcript can be detected by 1 h postinfection (hpi) until 12 hpi and a late one from 18hpi up to 48 hpi, while early and late transcripts of the AcMNPV me-53of the recombinant can be detected at 3 and 24 hpi, respectively. This suggested that the early and late promoters of both AcMNPV and TnSNPV me-53swere recognized in recombinant virus-infected cells. The regulatory elements of the TnSNPV me-53promoter were also analyzed.

36. Functional Characterization of the Ecdysteroid UDP-glucosyl Transferase Gene of Helicoverpa armigeraSingle-enveloped Nucleopolyhedrovirus Isolated in South Africa

Author

Khan, Sehaam, Sneddon, Kate, Fielding, Burtram, Ward, Vernon, and Davison, Sean

Abstract

The ecdysteroid UDP-glucosyltransferase (egt) gene of a single enveloped nucleopolyhedrovirus was located using an Hz-SNPV gene-specific probe. This SNPV was found infecting a colony of Helicoverpa armigera(HaSNPV) in the Western Cape region of South Africa. The open reading frame of the HaSNPV-SA egtis 1.548 nucleotides long and encodes a predicted protein of 516 amino acids with a Mrof 58,897-kDa. The 5′-noncoding region contained an early transcription initiation motif (CAGT) and a baculovirus late transcription motif (ATAAG). A transcription enhancer sequence (GATA) was also identified. Two possible TATA boxes together with am AT rich region were also recognized. A putative signal peptide of 20 residues was present at the N-terminus of the predicted EGT sequence. A polyadenylation signal (AATAAA) was found downstream of the translation stop codon. Five HelicoverpaNPV EGT's that have an extremely high degree of nucleotide and amino acid sequence homology were used in this study. Single nucleotide polymorphisms (SNPs) within the gene were tabulated. The HelicoverpaNPV egts seem to be closely related to the egtgenes of Mamestra configurataNPV (MacoNPV), Buzura suppressariaNPV (BusuSNPV) and Spodoptera exiguaNPV (SeMNPV) with amino acid identities of approximately 50%. The HelicoverpaNPV EGTs show ten conserved motifs with other EGTs. A phylogenetic tree of 27 baculovirus EGTs and a human UDP-glucoronosyltransferase was constructed using Neighbour-joining within CLUSTAL X. That a secreted and active EGT is encoded by HaSNPV-SA was confirmed by assay of infected cell culture medium.

Abstract

Baculovirus phylogeny based on a single gene may not accurately represent baculovirus relatedness. Phylogenetic trees might differ, depending on the genes used. An EcoRl genomic library of a single-capsid nucleopolyhedrovirus of Helicoverpa armigera (HaSNPV) was constructed with the plasmid pBluescript SK. Various clones ranging in size from 14 kb to 0.5 kb were constructed. Three important genes, late expression factor (lef) 8, chitinase and helicase, were identified during random sequence analysis of two clones (EcoRl-H and EcoRl-J), which formed part of the EcoRl plasmid library of the viral genome. Two of these genes, lef-8 and helicase, found to play a role in replication or expression, have been found in all baculovirus genomes sequenced to date. The genome sequence of PluteIIa xylostella granulovirus (PxGV) does not contain a chitinase gene. For each of the three genes, amino acid sequences were aligned with CLUSTAL X using default parameters and the Blosum matrix. Single nucleotide polymorphisms (SNPs) within each gene of the Helicoverpa SNPVs were tabulated. Trees were constructed using the neighbour-joining algorithm of CLUSTAL X and were rooted on Cydia pomonella GV. The resulting phylogenetic trees were visualized in Treeview. The two data sets of helicase and lef-8 yielded phylogenies supporting the separation of the Nucleopolyhedrovirus (NPV) and Granulovirus (GV) genera and further division of the NPVs into groups I and II. These two trees confirmed the placement of HaSNPV as a group II type NPV. The data set of chitinase incorrectly grouped the HaSNPV as part of the group I NPVs. [ABSTRACT FROM AUTHOR]

Abstract

In a worldwide collaborative effort, 19,630 Y-chromosomes were sampled from 129 different populations in 51 countries. These chromosomes were typed for 23 short-tandem repeat (STR) loci (DYS19, DYS389I, DYS389II, DYS390, DYS391, DYS392, DYS393, DYS385ab, DYS437, DYS438, DYS439, DYS448, DYS456, DYS458, DYS635, GATAH4, DYS481, DYS533, DYS549, DYS570, DYS576, and DYS643) and using the PowerPlex Y23 System (PPY23, Promega Corporation, Madison, WI). Locus-specific allelic spectra of these markers were determined and a consistently high level of allelic diversity was observed. A considerable number of null, duplicate and off-ladder alleles were revealed. Standard single-locus and haplotype-based parameters were calculated and compared between subsets of Y-STR markers established for forensic casework. The PPY23 marker set provides substantially stronger discriminatory power than other available kits but at the same time reveals the same general patterns of population structure as other marker sets. A strong correlation was observed between the number of Y-STRs included in a marker set and some of the forensic parameters under study. Interestingly a weak but consistent trend toward smaller genetic distances resulting from larger numbers of markers became apparent. Fil: Corach, Daniel. Universidad de Buenos Aires.

Abstract

During the study of genetic diversity at non-core Y-STRs in South African population groups, we identified loci with high discrimination capacity. In this study we present a detailed account of the allele diversity, allele sequence data, gene diversity, allele frequency spectrum and informativeness for assignment in the European English, Asian Indian and Xhosa population groups at loci DYS449, DYS481, DYS518, DYS612, DYS626, DYS644 and DYS710. The suitability of these loci for forensic, genealogical and evolutionary studies is discussed, and nomenclature for loci DYS518, DYS612, DYS626 and DYS644 is suggested.
