Resumo: | The objective of this work was to estimate the genetic variability level and distribution in Brazilian broodstocks of marine shrimp (Litopenaeus vannamei). Nine of the country’s largest hatcheries were evaluated using codominant and highly polymorphic microsatellite markers. The results obtained from genotyping of ten microsatellite loci are indicative of genetic variability that is compatible with that found in wild populations of L. vannamei in Mexico and Central America. A possible explanation is the highly diversified and relatively recent origin of the available broodstocks. Bayesian analysis detected a signal for five founding populations. The distribution of genetic distances partially reflects geographical location, and this information will be useful for the creation of new broodstocks. Therefore, L. vannamei genetic variability among nine of the largest national hatcheries can be considered high. |

Nove dos maiores laboratórios de maturação do país foram analisados por meio de marcadores microssatélites codominantes e altamente polimórficos. Os resultados obtidos a partir da genotipagem de dez locos de microssatélites são indicativos de variabilidade genética compatível com aquela encontrada em populações naturais de L. vannamei no México e na América Central. Uma possível explicação é a origem altamente diversificada e relativamente recente dos plantéis disponíveis. A análise bayesiana detectou sinal correspondente a cinco populações originais. A distribuição das distâncias genéticas reflete parcialmente a localização geográfica, e essa informação será útil na formação de novos plantéis. Portanto, a variabilidade genética de L. vannamei entre nove dos maiores laboratórios de maturação nacionais pode ser considerada alta.Pesquisa Agropecuaria BrasileiraPesquisa Agropecuária BrasileiraFINEP, FUNCAP, FAPEPI, CNPqMaggioni, RodrigoCoimbra, Maria Raquel MouraCosta, Raimundo Bezerra daDiniz, Fábio MendonçaMolina, Wagner FrancoOliveira, Diana Magalhães dePuchnick-Legat, Angela2013-10-31info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://seer.sct.embrapa.br/index.php/pab/article/view/11190Pesquisa Agropecuaria Brasileira; v.48, n.8, ago. 2013: Número Temático Aquacultura; 968-974Pesquisa Agropecuária Brasileira; v.48, n.8, ago. 2013: Número Temático Aquacultura; 968-9741678-39210100-104xreponame:Pesquisa Agropecuária Brasileira (Online)instname:Empresa Brasileira de Pesquisa Agropecuária (Embrapa)instacron:EMBRAPAenghttps://seer.sct.embrapa.br/index.php/pab/article/view/11190/12336https://seer.sct.embrapa.br/index.php/pab/article/downloadSuppFile/11190/6663https://seer.sct.embrapa.br/index.php/pab/article/downloadSuppFile/11190/6664info:eu-repo/semantics/openAccess2013-11-09T08:42:01Zoai:ojs.seer.sct.embrapa.br:article/11190Revistahttp://seer.sct.embrapa.br/index.php/pabPRIhttps://old.scielo.br/oai/scielo-oai.phppab@sct.embrapa.br || sct.pab@embrapa.br1678-39210100-204Xopendoar:2013-11-09T08:42:01Pesquisa Agropecuária Brasileira (Online) - Empresa Brasileira de Pesquisa Agropecuária (Embrapa)false |
