    DNA extraction from Oyster Larvae Crassostrea Gigas and Crassostrea Angulata

    Context

    This laboratory is working on the genetic diversity of cupped oysters at different scales. This study is focusing on hybridization and introgressive hybridization between the species C. gigas and C. angulata. Both, coming from Asia, are present in South Portugal in Europe. To characterize their relationship, F2 experimental crosses of biparental families were performed in our experimental hatchery. A panel of specific SNP will be used on each individual larvae. Therefore a grinding method is necessary to extract DNA. Our study was designed to see if the Precellys kit lysis permits to grind efficiently larvae to obtain homogenous lysis and good quality and quantity of DNA materials, with reproducibility, in order to perform PCR amplification.
