“…The cessation of recombination in stratum 4 leaves only a small ''pseudoautosomal region'' on the X and Y chromosomes where recombination still occurs. (Li et al 2003;Zhang et al 2007). Many species have X0 systems, including some nematodes and insects, and these most likely evolved from XY GSD (Shearman 2002), after genetic degeneration of the Y chromosome and movement of genes essential for male functions to other chromosomes.…”

The ability to identify genetic markers in nonmodel systems has allowed geneticists to construct linkage maps for a diversity of species, and the sex-determining locus is often among the first to be mapped. Sex determination is an important area of study in developmental and evolutionary biology, as well as ecology. Its importance for organisms might suggest that sex determination is highly conserved. However, genetic studies have shown that sex determination mechanisms, and the genes involved, are surprisingly labile. We review studies using genetic mapping and phylogenetic inferences, which can help reveal evolutionary pattern within this lability and potentially identify the changes that have occurred among different sex determination systems. We define some of the terminology, particularly where confusion arises in writing about such a diverse range of organisms, and highlight some major differences between plants and animals, and some important similarities. We stress the importance of studying taxa suitable for testing hypotheses, and the need for phylogenetic studies directed to taxa where the patterns of changes can be most reliably inferred, if the ultimate goal of testing hypotheses regarding the selective forces that have led to changes in such an essential trait is to become feasible.

“…To expedite the process of identifying genetic traits for optimal growth performance, marker-assisted selection (MAS) processes such as single nucleotides polymorphism (SNP), microsatellite, ampliied fragment length polymorphism (AFLP), random ampliied polymorphism DNA (RAPD), restriction fragment length polymorphism (RFLP) and quantitative trait loci (QTL) are being used to scan chromosomal DNA of diferent farmed aquatic organisms. Among these, the most widely used is QTL analysis, which has been applied across most of the commercial ish and crustacean species used in aquaculture [144][145][146][147]. As deined by Geldermann [148], QTLs are chromosomal regions made of single genes or gene clusters determining a quantitative character of a given trait.…”

Applications of RNA-Seq and Omics Strategies - From Microorganisms to Human Health

View full text Add to dashboard Cite

Gene expression studies in aquaculture have slowly evolved from the traditional reductionist approach of single gene sequencing to high throughput sequencing (HTS) techniques able to sequence entire genomes of living organisms. The upcoming of HTS techniques has led to emergence of metagenomics, nutrigenomics, epigenetics and other omics technologies in aquaculture in the last decade. Metagenomics analyses have accelerated the speed at which emerging pathogens are being discovered, thereby contributing to the design of timely disease control strategies in aquaculture. Using metagenomics, it is easy to identify and monitor microbial communities found in diferent ecosystems. In vaccine production, genomic studies are being used to identify cross neutralizing antigens against variant strains of the same pathogens. In genetics and epigenetics, genomics traits have been identiied that are beginning to gain commercial applications in aquaculture. Nutrigenomics have not only enhanced our understanding of the biological markers for nutrition-related diseases, but they have also enhanced our ability to formulate diets able to maintain a stable immune homeostasis in the gut. Overall, herein, we have shown that functional genomics provide multifaceted applications ranging from monitoring microbial communities in aquatic environments to optimizing production systems in aquaculture.

“…Molecular markers have been applied, for example, for analyzing the genetic diversity of wild shrimp resources (Xu et al, 2001), for strain and species identification in penaeids (Calo-Mata et al, 2009), and for parentage analysis in the black tiger shrimp Penaeus monodon (Jerry et al, 2006). In addition, linkage maps have been generated for several penaeid shrimp species, in most cases by using amplified fragment length polymorphism (AFLP) (Li et al, 2003;Zhang et al, 2007;Staelens et al, 2008). For prawns, however, no sex-specific markers have been identified, and to date P. monodon is the only decapod crustacean species for which sex-linked markers have enabled PCRbased differentiation of male from female prawns (Staelens et al, 2008).…”

“…Evidence for type and/or presence of sex chromosomes is drawn from physical mapping of sex-specific sequences, from sex-linked linkage maps, from karyological studies and from crosses of sexreversed individuals (Legrand et al, 1987;Sagi and Cohen, 1990;Griffiths and Orr, 1999;Li et al, 2003;Parnes et al, 2003). In Crustacea of the order Decapoda, karyotype studies have revealed distinguishable sex chromosomes only in crabs (Brachyura) and hermit crabs (Anomura), as reviewed by Parnes et al (2003).…”

Isolation and characterization of a female-specific DNA marker in the giant freshwater prawn Macrobrachium rosenbergii

et al. 2011

In this study, a female-specific DNA marker in the freshwater prawn Macrobrachium rosenbergii was identified through amplified fragment length polymorphism (AFLP). The AFLPderived sequence-characterized amplified region (SCAR) marker was tested in over 200 individuals, giving reproducible sex identification. Further molecular characterization of the sex-marker's genomic region (B3 kb long) revealed the presence of tandem and inverted repeats. The B3-kb sequence was identified both in male and female prawns, but with subtle differences: a deletion of 3 bp (present in female prawn but absent in male prawn) identified upstream of the SCAR marker sequence and two female-specific single-nucleotide polymorphisms, both indicating that male prawns are homozygous, whereas female prawns are heterozygous in this locus. Fluorescent in situ hybridization showed the B3-kb sequence to be unique: to the best of our knowledge, this is the first report of a unique sex-specific sequence observed in situ in crustaceans. The sex-specific marker identified in M. rosenbergii may have considerable applied merit for crustacean culture in that it will enable the determination of genetic sex at early developmental stages when phenotypic differences are not identifiable.
