This book was released on 2011 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: It has been hypothesized that salmonids use olfactory cues to return to their natal rivers and streams. However, the key components of the molecular pathway involved in imprinting and homing are still unknown. If odorants are involved in salmon homing migration then olfactory receptors should play a critical role in the dissipation of information from the environment to the fish. To understand the molecular basis for imprinting and homing in Atlantic salmon (Salmo salar), it is important to identify and characterize the olfactory receptors in the Atlantic salmon genome. Aquatic chemical cues are received through the salmon nares and into the nasal cavity that contains a single olfactory organ, olfactory rosette. The olfactory rosette contains sensory neurons, which are thought to express only one olfactory receptor. In this study, three major superfamilies of fish olfactory receptors (MOR, ora and OlfC) were examined. To identify the olfactory genes in Atlantic salmon several genomic and bioinformatic techniques were used. First, an Atlantic salmon bacterial artificial chromosome (BAC) library was screened with probes designed from previously identified fish olfactory receptor sequences. Then a selected number of hybridization positive BACs containing olfactory receptors were shotgun cloned and sequenced. From these BAC sequences, two ora genes and 55 OlfC genes were identified in Atlantic salmon. The second technique used to identify olfactory receptors in Atlantic salmon was a bioinformatic approach that involved screening a 3-fold Atlantic salmon genome sequence for olfactory receptors. Using this approach, 24 MOR and the remaining five ora genes were identified, as well as another 24 partial genes or pseudogenes. As a first step to understand how olfactory receptors are involved in imprinting and homing, a suite of olfactory receptors were selected to examine the expression profiles of these genes across different life stages and life histories of wild Atlantic salmon from Newfoundland, Canada. Seven differentially expressed OlfC genes were identified in juvenile anadromous salmon compared to returning adult salmon. From this research, I hypothesize that OlfC genes may play an important role in the imprinting of home stream water olfactory cues in anadromous Atlantic salmon.

This book was released on 2014 with total page 95 pages. Available in PDF, EPUB and Kindle. Book excerpt: It is widely hypothesized that Atlantic salmon are imprinted at a young age with olfactory cues, which they use as a guide in order to return to their natal streams to spawn. However, the molecular mechanism(s) behind this biological phenomenon remain unknown. Therefore, in order to better understand imprinting and homing in Atlantic salmon, it is important to characterize the repertoire of olfactory receptors in thisspecies. A search of the first assembly of the Atlantic salmon genome revealed 27 putatively functional trace amine-associated receptor (TAAR) genes and 25 putative TAAR pseudo-genes. Genetic mapping, phylogenetic analysis, binding-site prediction, and quantitative PCR were performed using the Atlantic salmon TAAR genes. The identification of this gene family in Atlantic salmon will facilitate additional studiesinvolving olfaction and homing such as determining the range of allelic variation in olfactory receptors genes of different salmon populations.

This book was released on 2010 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Large-scale expressed sequence tags (ESTs) in Atlantic salmon (Salmo salar) are examined to answer questions regarding salmonid transcriptomes. ESTs represent raw and incomplete gene sequences that need to be read, assembled and analyzed with computer software. The goal of this thesis was to develop an automatically curated and publicly accessible set of annotated full-length genes, representing a near-complete transcript set for Salmo salar. In turn, these genes provide the framework for studies in gene expression, conservation, and molecular evolution. The work presented here also touches on the results of a molecular evolution study, as an example of how full-length gene identification can be used to answer biological questions. Previous to this study, a limited number of Atlantic salmon cDNA libraries and ESTs were known. To further the goal of determining complete gene sequences, highly enriched full-length cDNA libraries and full-length libraries were created and sequenced, resulting in the ability to identify a large number of full-length reference genes. Together, all libraries represent a diverse pool of transcriptome sequences for Salmo salar. The goal of producing an accurate large-scale full-length gene set on a duplicated genome is not trivial. Complete systems for this objective do not readily exist. EST sequencing, EST assembly, and data storage, are just a few of the initial computational issues that are addressed. Once these issues are resolved, the multi-step workflow of full-length gene determination is described. The final challenge involving the development of a concise and universally accessible system for visualization is discussed. The resulting computational framework that has been developed is shown to be able to handle the intricacies and the size of a duplicated salmonid genome. It has been largely accepted that Atlantic salmon have undergone a recent genome duplication. Gene paralogs provide one source of evidence for this event. Analysis of paralogs revealed signatures of asymmetric evolution possibly due to relaxation of selective pressure. This thesis provides a complete Bioinformatics analysis pipeline to analyze and to visualize a set of full-length reference genes for Atlantic salmon. Using full-length genes as a framework, the topic of molecular evolution was addressed to show evidence of asymmetrical evolution among gene duplicates. The full-length reference genes, along with ESTs and all putative transcripts, have been made publicly available. These results serve as a valuable genomic resource for next-generation sequencing and for all other salmonid research endeavours.

Available in PDF, EPUB and Kindle. Book excerpt: Atlantic Salmon is a cultural icon throughout its North Atlantic range; it is the focus of probably the World’s highest profile recreational fishery and is the basis for one of the World’s largest aquaculture industries. Despite this, many wild stocks of salmon are in decline and underpinning this is a dearth of information on the nature and extent of population structuring and adaptive population differentiation, and its implications for species conservation. This important new book will go a long way to rectify this situation by providing a thorough review of the genetics of Atlantic salmon. Sponsored by the European Union and the Atlantic Salmon Trust, this book comprises the work of an international team of scientists, carefully integrated and edited to provide a landmark book of vital interest to all those working with Atlantic salmon.
