Methanococcus jannaschii genome: revisited.
Analysis of genomic sequences is necessarily an ongoing process. Initial gene assignments tend (wisely) to be on the conservative side (Venter, 1996). The analysis of the genome then grows in an iterative fashion as additional data and more sophisticated algorithms are brought to bear on the data. The present report is an emendation of the original gene list of Methanococcus jannaschii (Bult et al., 1996). By using a somewhat more updated database and more relaxed (and operator-intensive)...
Chromosomal distribution of 320 genes from a brain cDNA library.
We have determined the chromosomal assignment of 320 brain expressed genes by studying the segregation of polymerase chain reaction (PCR) products in human rodent somatic cell hybrids and by genetically mapping polymorphic cDNAs using the CEPH (Centre d'Etude du Polymophisme Humaine) reference pedigrees and database. These mapped genes can function as markers on the physical map of the human genome, as well as serve as candidate disease gene loci. Distribution of these genes to the human...
FgBud3, a Rho4-Interacting Guanine Nucleotide Exchange Factor, Is Involved in Polarity Growth, Cell Division and Pathogenicity of Fusarium graminearum.
Rho GTPases are signaling macromolecules that are associated with developmental progression and pathogenesis of . Generally, enzymatic activities of Rho GTPases are regulated by Rho GTPase guanine nucleotide exchange factors (RhoGEFs). In this study, we identified a putative RhoGEF encoding gene () in database and proceeded further by using a functional genetic approach to generate targeted gene deletion mutant. Phenotypic analysis results showed that the deletion of caused severe...
Virtual Comparative Metagenomics
We have created an open virtualization format (OVF) package of JCVI's Metagenomics Reports (METAREP)- a high performance comparative metagenomics analysis tool. The software runs on a web server, retrieves data from two different database systems and uses R for statistical analysis. The new OVF package bundles all these 3rd party tools and is configured to run out of the box in a virtual machine. To run a virtual version of METAREP on your machine, follow these steps download the...
The HuRef Browser: a web resource for individual human genomics.
The HuRef Genome Browser is a web application for the navigation and analysis of the previously published genome of a human individual, termed HuRef. The browser provides a comparative view between the NCBI human reference sequence and the HuRef assembly, and it enables the navigation of the HuRef genome in the context of HuRef, NCBI and Ensembl annotations. Single nucleotide polymorphisms, indels, inversions, structural and copy-number variations are shown in the context of existing...
Novel Diversity of Bacterial Communities Associated with Bottlenose Dolphin Upper Respiratory Tracts
Respiratory illness is thought to be most the common cause of death in both wild and captive populations of bottlenose dolphins (Tursiops truncatus). The suspected pathogens that have been isolated from diseased animals have also been isolated from healthy individuals, suggesting they may be part of the normal flora. Our current understanding of the bacteria associated with the upper respiratory tract (URT) of bottlenose dolphins is based exclusively upon culture-based isolation and...
Development and evaluation of an Arabidopsis whole genome Affymetrix probe array.
We describe the development of a high-density Arabidopsis'whole genome' oligonucleotide probe array for expression analysis (the Affymetrix ATH1 GeneChip probe array) that contains approximately 22 750 probe sets. Precedence on the array was given to genes for which either expression evidence or a credible database match existed. The remaining space was filled with 'hypothetical' genes. The new ATH1 array represents approximately 23 750 genes of which 60% were detected in RNA from cultured...
Metagenome and Metatranscriptome Analyses Using Protein Family Profiles.
Analyses of metagenome data (MG) and metatranscriptome data (MT) are often challenged by a paucity of complete reference genome sequences and the uneven/low sequencing depth of the constituent organisms in the microbial community, which respectively limit the power of reference-based alignment and de novo sequence assembly. These limitations make accurate protein family classification and abundance estimation challenging, which in turn hamper downstream analyses such as abundance profiling...
Influenza Genome Sequencing Project Is Launched
November 15, 2004 Rockville, MD — The Institute for Genomic Research (TIGR) will sequence a large number of human isolates of the influenza virus as part of a landmark influenza genome sequencing project announced Monday by the National Institute of Allergy and Infectious Diseases (NIAID), part of the National Institutes of Health. The influenza sequencing project aims to help scientists better understand the emergence of annual influenza outbreaks — as well as the occasional...
