Abstract: La concha de abanico (Argopecten purpuratus) es un molusco bivalvo de importancia económica para el Perú, debido a su alto valor nutritivo y su amplia aceptación en los mercados de Estados Unidos, Japón y Europa. En el Perú, no se han realizado estudios a nivel genético poblacional en esta especie, existiendo solamente estudios morfométricos, cuyas variaciones estarían ligadas a cambios en la variabilidad genética del recurso (Cisneros et al., 2008). Además, existen pocos marcadores microsatélites reportados, los cuales son los marcadores moleculares más adecuados para evaluar la diversidad genética de una especie. El objetivo del presente estudio fue detectar microsatélites trinucleótidos “CAT” del genoma de A. purpuratus para lo cual se utilizó el método de librerías genómicas enriquecidas. Se optimizó un protocolo para extracción de DNA Genómico de alta calidad a partir de la gónada masculina y utilizando como buffer de lisis TNES-urea. Asimismo, se construyó una librería genómica enriquecida utilizando esferas magnéticas lo que permitió obtener un elevado porcentaje de clones positivos (65 80%). Finalmente, se obtuvo DNA plasmídico de alta calidad cuyo secuenciamiento servirá para diseñar cebadores que permitan evaluar el polimorfismo de los microsatélites.
Palabras clave: concha de abanico, Argopecten purpuratus, librerías genómicas enriquecidas, microsatélites, polimorfismo.
--- The Peruvian scallop (Argopecten purpuratus) is an economically important bivalve in Peru due to its high nutritional qualities and its wide acceptance in the markets of United States, Japan and Europe. In Peru, there have not been studies of this resource at the population genetic level and there are only morphometric studies, one of those reports that variations at this level could be linked to the genetic variability of the resource (Cisneros et al., 2008). In addition, there are only few microsatellite markers reported, this molecular markers are the best to assess the genetic diversity. Due to this reason, the aim of this study was to detected trinucleotide microsatellites with the motif “CAT“ from the genome of A. purpuratus using enriched genomic libraries. High quality DNA extraction from the male gonad with TNES-urea lysis buffer was optimized. Furthermore, the enriched genomic libraries constructed using magnetic beads allowed identification of a high percentage of positive clones (65-80%). Finally, the sequencing of the high quality plasmid DNA obtained will enable primers design for the evaluation of the microsatellites polymorphism. Keywords: Peruvian scallop, Argopecten purpuratus, enriched genomic libraries, microsatellite, polymorphism.
