SNP arrays are enabling tools for high-resolution studies of the genetic basis of complex traits in farmed and wild animals. Oysters are of critical importance in many regions from both an ecological and economic perspective, and oyster aquaculture forms a key component of global food security. The aim of our study was to design a combined-species, medium density SNP array for Pacific oyster (C...
BACKGROUND Crassostrea gigas accumulates diarrheic shellfish toxins (DSP) associated to Prorocentrum lima of which Okadaic acid (OA) causes specific inhibitions of serine and threonine phosphatases 1 and 2A. Its toxic effects have been extensively reported in bivalve mollusks at cellular and physiological levels, but genomic approaches have been scarcely studied. METHODOLOGY/PRINCIPAL FINDING...
The genetic diversity of the specimens of four natural populations of Arapaima from Araguaia-Tocantins basin was assessed within and among these stocks, using five primers for ISSR. COI (cytochrome c oxidase subunit I) partial sequences confirmed that the specimens belongs to Arapaima gigas. The ISSR provided 168 loci, of which 165 were polymorphic. However, the number of loci for each populati...
The present study reports the first population genetic analysis of Arapaima gigas, an important but critically over-exploited fish species of the Amazon basin. We sequenced two discontinuous mitochondrial DNA regions of 1204 base-pairs (bp) (NADH1 segment) and 1143 bp (ATPase segment) from 139 individuals of A. gigas representing eight localities spanning the Amazon basin from Iquitos, Peru to ...
We sequenced the complete mitochondrial genome of the pirarucu, Arapaima gigas, the largest fish of the Amazon basin, and economically one of the most important species of the region. The total length of the Arapaima gigas mitochondrial genome is 16,433 bp. The mitochondrial genome contains 13 protein-coding genes, two rRNA genes and 22 tRNA genes. Twelve of the thirteen protein-coding genes ar...
