    Development of microsatellite markers in the toxic dinoflagellate Alexandrium minutum (Dinophyceae)

    Outbreaks of paralytic shellfish poisoning caused by the toxic dinoflagellate Alexandrium minutum (Dinophyceae) are a worldwide concern from both the economic and human health points of view. For population genetic studies of A. minutum distribution and dispersal, highly polymorphic genetic markers are of great value. We isolated 12 polymorphic microsatellites from this cosmopolitan, toxic dinoflagellate species. These loci provide one class of highly variable genetic markers, as the number of alleles ranged from 4 to 12, and the estimate of gene diversity was from 0.560 to 0.862 across the 12 microsatellites; these loci have the potential to reveal genetic structure and gene flow among A. minutum populations.

    Using global genome approaches to address problems in cod mariculture
    ( 2005-10-26) Goetz, Frederick W. ; McCauley, Linda A. R. ; Goetz, Giles W. ; Norberg, Birgitta
    A number of techniques including expressed sequence tag (EST) analysis, serial analysis of gene expression, and microarrays are available to study the global expression and regulation of genes. Many of these techniques are being used for intensively reared fish such as trout, salmon and catfish to study genes involved in growth, reproduction and health. In contrast, relatively little is known about the composition and regulation of transcriptomes in gadids. However, several bottlenecks in cod mariculture might benefit from the discovery and analysis of genes involved in reproduction, growth and disease. As a result, we have begun EST analysis of genes in the cod ovary. Complimentary DNA (cDNA) libraries of cod ovaries taken from females at oocyte final maturation and ovulation have been constructed, and 1,361 ESTs have been analyzed. As expected, several oocyte-related genes were observed including various zona pellucida egg membrane proteins. However, pivotal cell cycle regulators such as cyclins, genes involved in the regulation of apoptosis such as the Bcl-2-related ovarian killer protein, and hormone receptor components were also observed. Finally, a cDNA for a potential novel cod antifreeze protein was observed 12 times, suggesting the existence of a cod egg-specific antifreeze protein.
