Abstract: Introduction Members of the genus Bifidobacterium are Gram-positive, strictly anaerobic, relatively high GC, fermentative rods, often Y shaped or clubbed at the ends. Bifidobacterium species represent a major element in the microflora of the human gastrointestinal tract (GIT). They are considered to have a health-promoting role of their host, and there is mounting evidence pointing to the activity of these bacteria in mediating health attributes such as alleviation of lactose tolerance, stimulation/potentia tion of the immune system, and production of vitamins and antimicrobials [1]. Bifidobacterium species are also used in the production of fermented dairy products and are believed to play a pivotal role in maintaining a well-balanced intestinal flora in healthy humans[2]. In order to investigate the primary genetic structure of a probiotic Bifidobacterium, the B. breve strain NCIMB 8807 was selected and random sequences were generated to give a coverage of about five fold. These seque
If a particular protein encoded in the genome is a metabolic enzyme, it will then catalyze a specific reaction(s). Heterogeneous data types associated with this dogma include genomic data (which defines the messages and the resulting protein sequences), transcriptomic data (which reveals the levels of messages present), proteomic data (which gives the levels of each protein present), and ?fluxomic ? data (which, if it existed, would provide measurements of intracellular fluxes on a complete scale). The reaction associations shown here refer to:...
To elucidate the evolutionary mode of the formation of species via polyploidization, we conducted phylogenetic analysis of the U genome of the UM genome tetraploid Aegilops species, Ae. columnaris and Ae. triaristata. Using the genome-specific PCR primer set U31, we investigated the variation of the U genome of 48 accessions each of Ae. columnaris and Ae. triaristata and 72 accessions of their diploid ancestor Ae. umbellulata. As a result, three alleles were distinguishable by amplified length and CAPS polymorphisms, namely, allele I = normal s...
BACKGROUND: Brassica rapa is one of the most economically important vegetable crops worldwide. Owing to its agronomic importance and phylogenetic position, B. rapa provides a crucial reference to understand polyploidy-related crop genome evolution. The high degree of sequence identity and remarkably conserved genome structure between Arabidopsis and Brassica genomes enables comparative tiling sequencing using Arabidopsis sequences as references to select the counterpart regions in B. rapa, which is a strong challenge of structural and comparati...
The genomes of barley and wheat, two of the world's most important crops, are very large and complex due to their high content of repetitive DNA. In order to obtain a whole-genome sequence sample, we performed two runs of 454 (GS20) sequencing on genomic DNA of barley cv. Morex, which yielded approximately 1% of a haploid genome equivalent. Almost 60% of the sequences comprised known transposable element (TE) families, and another 9% represented novel repetitive sequences. We also discovered high amounts of low-complexity DNA and non-genic low-...
The evidence of a direct link between increased genome/epigenome damage and elevated risk for adverse health outcomes during the various stages of life, such as infertility, foetal development and cancer is becoming increasingly stronger. The latter is briefly reviewed against a background of evidence indicating that genome and epigenome damage biomarkers, in the absence of overt exposure of genotoxins, are themselves sensitive indicators of deficiency in micronutrients required as cofactors or as components of DNA repair enzymes, for maintenan...
Brassica crop species are of worldwide importance and are closely related to the model plant Arabidopsis thaliana for which the complete genome sequence has recently been established. We investigated collinearity of marker order by comparing two contrasting regions of the Brassica oleracea genome with homologous regions of A. thaliana. Although there is widespread replication of marker loci in both A. thaliana and B. oleracea, we found that a combination of genetic markers mapped in B. oleracea, including RFLPs, CAPS, and SSRs allowed compariso...
Epstein-Barr virus (EBV) is associated with malignant diseases of lymphoid and epithelial cell origin. The tropism of EBV is due to B-cell-restricted expression of CD21, the major receptor molecule for the virus. However, efficient infection of CD21- epithelial cells can be achieved via transfer from EBV-coated B cells. We compare and contrast here the early events following in vitro infection of primary B cells and epithelial cells. Using sensitive, quantitative reverse transcription-PCR assays for several latent and lytic transcripts and two-...
Genome projects for the parasitic helminths Brugia malayi (a representative filarial nematode) and Schistosoma were initiated in 1995 by the World Health Organization with the ultimate objectives of identifying new vaccine candidates and drug targets and of developing low resolution genome maps. Because no genetic maps are available, and very few genes have been characterized from either parasite group, the first goal of both Initiatives has been to catalogue new genes for future placement on chromosome and physical maps. These genes have been ...
An important approach for understanding complex disease risk using the mouse is to map and ultimately identify the genes conferring risk. Genes contributing to complex traits can be mapped to chromosomal regions using genome scans of large mouse crosses. Congenic strains can then be developed to fine-map a trait and to ascertain the magnitude of the genotype effect in a chromosomal region. Congenic strains are constructed by repeated backcrossing to the background strain with selection at each generation for the presence of a donor chromosomal ...
The development of fast and inexpensive methods for sequencing bacterial genomes has led to a wealth of data, often with many genomes being sequenced of the same species or closely related organisms. Thus, there is a need for visualization methods that will allow easy comparison of many sequenced genomes to a defined reference strain. The BLASTatlas is one such tool that is useful for mapping and visualizing whole genome homology of genes and proteins within a reference strain compared to other strains or species of one or more prokaryotic orga...
The two parental genomes lie separate within the zygote and may be differentially affected by environmental influences. We have shown earlier (Russell et al., 1988) that the maternal genome within the mouse zygote is exquisitely sensitive to the induction of point mutations by N-ethyl-N-nitrosourea (ENU), and that the initial lesion probably occurs in one strand of the DNA. The present experiment measured specific-locus mutation induction in the paternal genome. Zygotes containing a multiple-recessive maternal genome (a; b; p cch; d se; s) and ...
The rice genome has now been sequenced using whole-genome-shotgun and map-based methods. The relative merits of the two methods are the subject of debate, as they were in the human genome project. In this Opinion article, we will show that the serious discrepancies between the resultant sequences are mostly found in the large transposable elements such as copia and gypsy that populate the intergenic regions of plant genomes. Differences in published gene counts and polymorphism rates are similarly resolved by considering how transposable elemen...
