| The complete sequence of the mitochondrial genome of Chinook salmon, Oncorhynchus tshawytscha, has been determined. The circular genome consisting of 16,644 base pairs encodes thirteen proteins, the 12S and 16S ribosomal RNAs, and 22 transfer RNAs. These genes are ordered in the same way as most other vertebrates. The nucleotide and amino acid sequences of the ribosomal RNAs and the thirteen protein-coding genes were compared with those of other salmonids such as Oncorhynchus mykiss, Salmo salar, Salvelinus fontinalis, Salvelinus alpinus and Coregonus lavaretus. The sequence features of the control region (D-loop), the origin of L-strand replication and a putative peptide codified by the 16S mitochondrial RNA are described and discussed. |

| The use of transgenic models for the study of neurodegenerative diseases has made valuable contributions to the field. However, some important limitations, including protein overexpression and general systemic compensation for the missing genes, has caused researchers to seek natural models that show the main biomarkers of neurodegenerative diseases during aging. Here we review some of these models-most of them rodents, focusing especially on the genetic variations in biomarkers for Alzheimer diseases, in order to explain their relationships with variants associated with the occurrence of the disease in humans. |

| ABSTRACT The type strain SUR2 of the novel species Chryseobacterium limigenitum was isolated from a dehydrated sludge of the municipal sewage treatment plant in Dogoše near Maribor in Slovenia. The draft genome, with 60 contigs, 4,697,725 bp, 34.4% of G+C content, was obtained using the Illumina HiSeq 2500-1 platform. Joint Genome Institute Microbial Genome Annotation Pipeline (MGAP v.4) has identified 4322 protein-coding sequences including resistance genes against arsenic and other heavy metals. In addition, a subclass B3 metallo-β-lactamase, which confers resistance to penicillins, cephalosporins and carbapenems, was also present in the genome. The genome sequence provides important information regarding bioremediation potential and pathogenic... |

El fitoplasma Maize Bushy Stunt (MBS) se identifico por PCR se detectó en plantas con los síntomas antes descritos, en los municipios de Tlalixcoyan, Cosoleacaque y Paso de Ovejas en 2006 y 2007. Los genotipos CP-562, 30F83, 30F92, Orca, 30F96, Nutria y Asgrow 7573 resultaron positivos a la presencia del MBS, mientras que en 3086, 30F97 y CP-560 no se detectó la presencia del MBS en una plantación experimental en plantas sintomáticas en Tlalixcoyan, Ver. en 2006 y 2007.... |

| The present reflection refers to data obtained about the social representations of genomic research and its applications through interviews with legislators and lawyers, biomedical researchers and civilians and the review of scientific and legal literature in four Latin American countries: Argentine, Chile, Mexico and Peru. Several issues are addressed: little access to prevention and therapeutic methods, lack of equity in health benefits, commercialization of gene sequences through patents which leads to commercial exploitation of underdeveloped countries, the possibility of physical or psychological damage or genetic discrimination, the possibility of genetic modifications or abortion for eugenic reasons, the necessity of safeguarding confidentiality,... |

| Recent advances in functional genomics allow us to estimate the expression of several thousands of genes in the mammalian genome. Techniques such as microarrays, expressed tag sequencing (EST), serial analysis of gene expression (SAGE), subtractive cloning and differential display (DD), and two-dimensional electrophoresis gel have been extensively used to screen and analyze parallel gene expression. Some pathological processes, for example, tumorigenesis and solid tumour growth, in which the former is derived from a single-cell and the latter has a mixed-cell problem, present new challenges to the limit of these functional genomic techniques. To fully understand the functions of cells in tumorigenesis or in heterogeneous solid tumour masses, it is... |

| This is a report on the analysis of genes involved in translation of the complete genomes of Mycoplasma hyopneumoniae strain J and 7448 and Mycoplasma synoviae. In both genomes 31 ORFs encoding large ribosomal subunit proteins and 19 ORFs encoding small ribosomal subunit proteins were found. Ten ribosomal protein gene clusters encoding 42 ribosomal proteins were found in M. synoviae, while 8 clusters encoding 39 ribosomal proteins were found in both M. hyopneumoniae strains. The L33 gene of the M. hyopneumoniae strain 7448 presented two copies in different locations. The genes encoding initiation factors (IF-1, IF-2 and IF-3), elongation factors (EF-G, EF-Tu, EF-Ts and EF-P), and the genes encoding the ribosome recycling factor (frr) and one polypeptide... |

| Expressed Sequence Tags (ESTs) sequencing provides reliable and useful information concerning gene expression patterns in the genomic context. Our group used bioinformatics to identify and annotate 5'EST-contigs belonging to the molecular chaperones within the Eucalyptus Genome Sequencing Project Consortium (FORESTs) database. We found that 1,959 5'EST-contigs, or approximately 1.6% of the total 5'EST-contigs, encoded chaperones, emphasizing their biological importance. About 55% of the chaperones that we found were Hsp70 chaperones and its co-chaperones, 18% were Hsp90 chaperones, 15% were Hsp60 and its co-chaperone, 8% were Hsp100 chaperones, and 4% were Small Hsps. We also investigated the digital expression profile of the chaperone genes to gain... |

| The completion of the genome sequencing of the Arabidopsis thaliana model system provided a powerful molecular tool for comparative analysis of gene families present in the genome of economically relevant plant species. In this investigation, we used the sequences of the Arabidopsis Hsp70 gene family to identify and annotate the Citrus Hsp70 genes represented in the CitEST database. Based on sequence comparison analysis, we identified 18 clusters that were further divided into 5 subgroups encoding four mitochondrial mtHsp70s, three plastid csHsp70s, one ER luminal Hsp70 BiP, two HSP110/SSE-related proteins and eight cytosolic Hsp/Hsc70s. We also analyzed the expression profile by digital Northern of each Hsp70 transcript in different organs and in response... |
