Abstract The whole-genome duplication 80 million years ago of the common ancestor salmonids (salmonid-specific fourth vertebrate duplication, Ss4R) provides unique opportunities to learn about evolutionary fate a duplicated genome in 70 extant lineages. Here we present high-quality assembly for Atlantic salmon ( Salmo salar ), and show that large genomic reorganizations, coinciding with bursts transposon-mediated repeat expansions, were crucial post-Ss4R rediploidization process. Comparisons...
The International Collaboration to Sequence the Atlantic Salmon Genome (ICSASG) will produce a genome sequence that identifies and physically maps all genes in salmon acts as reference for other salmonids.
This study uses phylogenetic relationships of New World representatives the species-rich genus Astragalus (Leguminosae; Papilionoideae) to follow up on recent evidence pointing rapid and plant diversification patterns in Andes. Bayesian maximum likelihood analyses were done using nuclear rDNA ITS chloroplast spacers trnD-trnT trnfM-trnS1, either separately or combination. The effect partitioned vs. nonpartitioned a approach was evaluated. Highest resolution obtained when data combined...
Abstract Metal pollution is a major global issue in aquatic environments, affecting environmental quality and potentially altering host–parasite dynamics. This study evaluates the buffering role of larval trematode Himasthla sp. under experimental conditions to test effect copper (Cu) exposure on survival marine snail Echinolittorina peruviana. Snails were collected from intertidal rocky pools over two-month period Coloso (23°45’S, 70°28’W), northern Chile, identified as parasitized or...
A síndrome de Down (SD) ou trissomia do cromossomo 21 é uma alteração genética produzida pela presença um a mais no par número 21. Isso quer dizer que, as pessoas com SD têm 47 cromossomos em suas células ao invés 46, como maior parte da população. Nesse sentido, este estudo, objetivamos compreender ocorre inclusão e o processo ensino-aprendizagem crianças partir análise dos artigos selecionados nos periódicos acadêmicos que publicam sobre tema. Trata-se pesquisa bibliográfica abordagem...
The use of DNA-based methodologies in identification hake species belonging to the Merluccius genus was shown be successful. A short fragment left hypervariable domain mitochondrial control region amplified, sequenced, and digested from 11 species. hake-specific PCR product, due its limited size, obtained a variety tissue samples with different levels DNA concentration degradation, including sterilized food products. On basis this phylogenetically informative 156-bp sequence were selected...
Varying levels of lupin (Lupinus albus), peas (Pisum sativum) and rapeseed (Brassica napus) meals were evaluated as partial replacements for fishmeal in extruded diets rainbow trout, with particular emphasis on the effect growth performance expression three genes associated immune response. A series 10 isonitrogenous (450 g kg−1 crude protein) isolipidic (17 g kg−1 lipid) formulated to contain different (150 g kg−1, 250 g kg−1 350 g kg−1), cake (100 g kg−1, 200 g kg−1 300 g kg−1) pea...
Patagonian toothfish (Dissostichus eleginoides) is a hefty notothenioid fish and key species within the marine ecosystem with high migratory capacity across sub-Antarctic south American Pacific oceans. Transcriptome characterization molecular markers associated micro macro-evolutionary studies are not available, which in turn limits gain of knowledge about genetic basis this species. Therefore, present study, de novo transcriptome from eight tissue an embryonic state was developed, using...
Metal pollution is a worldwide problem and one of the greatest threats to ecosystem integrity due its toxicity, persistence, bioaccumulation in biological systems. Anthropogenic impacts marine organisms host-parasite dynamics, with northern Chilean coast experiencing elevated copper levels waters sediments mining activities. In this study, we assessed effects exposure concentrations at low high-water temperatures on survival longevity parasite Himasthla sp. cercariae (Trematoda: Digenea)...
Both the records and descriptions of crustose species coralline algae on southeastern coast South America are from early 1900s. Unlike other Chile, biogeography distribution corallines have not been studied despite their abundance. Through recent studies, it has determined that genus Spongites is most conspicuous along rocky intertidal Chilean coasts. It also common to entire Southern Hemisphere; however, relationship between possible reasons for unknown. We used nuclear mitochondrial...
Sorgoleone (SGL) exuded by sorghum roots inhibits the development of some weeds. Due to its high hydrophobicity, it is expected that SGL presents low soil mobility and limited allelopathic activity in field. This work aims evaluate sorptivity sorgoleone octanol-water under two solvent systems. The systems were methanol:water (60:40) (MeOH:H2O) pure methanol (MeOH). These promote different conditions for solubility. Treatments arranged a 2 × 6 factorial (solvent equilibrium concentrations...
A set of expressed sequence tag-simple repeat (EST-SSR) markers for the genus Mytilus was developed through bioinformatic mining GenBank public database. total 33 782 EST sequences from were downloaded and screened di-, tri- tetranucleotide, with 1274 containing SSR markers. Nine microsatellite characterized in californianus a number alleles per locus ranging two to six, observed expected heterozygosities 0.490 0.730 0.510 0.860 respectively. Cross-species amplification achieved several...
Innate pathway activation is fundamental for early antiviral defense in fish, but currently there insufficient understanding of how salmonid fish identify viral molecules and activate these pathways.The Toll-like receptor (TLR) believed to play a crucial role host pathogenic microbes the innate immune system.In present study, full-length cDNA Salmo salar TLR3 (ssTLR3) was cloned.The ssTLR3 sequence 6071 bp long, containing an open reading frame 2754 encoding 971 amino acids.The TLR group...
MicroRNAs are key non-coding RNA molecules that play a relevant role in the regulation of gene expression through translational repression and/or transcript cleavage during normal development and physiological adaptation processes like stress. Quantitative reverse transcription polymerase chain reaction (RT-qPCR) has become approach normally used to determine levels microRNAs. However, this needs use endogenous reference. An improper selection references can result confusing interpretation...
Abstract We describe an emerging initiative - the ‘Functional Analysis of All Salmonid Genomes’ (FAASG), which will leverage extensive trait diversity that has evolved since a whole genome duplication event in salmonid ancestor, to develop integrative understanding functional genomic basis phenotypic variation. The outcomes FAASG have diverse applications, ranging from improved evolution, through improving efficiency and sustainability aquaculture production, supporting future fundamental...
The Atlantic salmon (Salmo salar) is a very valuable commercial salmonid species.As with other aquaculture species, intensive of often faces disease problems especially in early life stages which can limit stable production the species.'Ssa miRNAs DB', bioinformatics and manually curated database, aims at providing comprehensive resource microRNA Altantic salmon, user friendly interface for convenient retrieval each entry by ID or target gene.The current version Ssa DB involved prediction 41...
