“…In this study, the genetic variation observed between islands (F ST =0.04, p≤0.05) evidences the absence of the population structure of this species for the COI gene in the Tumaco cove, values that were also similar to those reported in studies for other mollusks (15,19). On the other hand, the analysis by populations pairs showed no differences between pairs of islands: El Pajal and San Jorge, La Playa and San Jorge, El Pajal and La Tiburonera, Bajito Vaqueria and La Tiburonera, or between Bajito Vaqueria and El Pajal.…”

“…Similarly, for a domesticated mussel Mytilus coruscus, it shows a genetic diversity with the same tendency (H=0.895 and π=0.008), (15). These diversity results indicate a possible population expansion (16); however, more advanced studies are needed to specify this aspect such as metagenomics, epigenomics, proteomics, metabolomics (17).…”

“…Del mismo modo, para un mejillón domesticado Mytilus coruscus, obtiene una diversidad genética con la misma tendencia (H=0.895 y π=0.008), (15 A pesar que los estudios reportan la misma relación entre diversidad haplotípica y nucleotídica Regionieri et al (14) y González et al (16), informan valores mayores a los encontrados para A. tuberculosa en el presente estudio (h=0.683). Esta pérdida de variabilidad probablemente se asocia a la pesca de esta especie sin restricción de captura por talla mínima (1,18), evitando de este modo el flujo genético a la siguiente generación.…”

Objective. To estimate the genetic diversity of the Anadara tuberculosa en five mangrove swams of Tumaco, Nariño, Colombia using as a mitocondrial molecular marker the cytochromo oxidase sub-unit I (COI). Materials and methods. A total of 50 individuals were collected from the San Jorge, La Tiburonera, El Pajal, La Playa y Bajito Vaquería mangrove swamps, randomly selecting 10 specimens of each zone. The tissue sample was worked with absolute alcohol at ambient temperature in microtubes. DNA was extracted, and the mitocondrial DNA was amplified using the PCR technique (polymerase chain reaction). The amplified and quantified products of PCR were sequenced on both sides (Macrogen). Each one of the obtained sequences was edited and aligned. Later, the parameters of genetic diversity (haplotypical and nucleotidical) were measured, and the analysis of distribution between frequency pairs (Mistmach distribution) was elaborated. Finally, the analysis of nucleotidic variation and population structure (AMOVA) was completed. Results. The amplified product gene weighed 710 bp. The haplotypical diversity reported for all the populations was high (0.683±0.060) and the reported nucleotídical diversity was low for all the populations (0.040±0.020). The AMOVA results indicate that the variance amongst populations is low (4.20%) and that the variance within populations is high (95.80%). Conclusions. The studied populations are not structured and although there is a decrease of natural banks, the genetic diversity is high.

“…The cultured juveniles primarily originate from natural populations. In the last few decades, natural juvenile stocks have decreased, while mussel farms have increased (Shen et al, 2009). Recently, breeding programs of M. coruscus have been initiated, mainly aiming to improve growth rates and disease resistance under aquaculture conditions.…”

The hard-shelled mussel (Mytilus coruscus) is an economically important shellfish that has been cultivated for the last decade. Due to over-exploitation, most mussel stocks have dramatically declined. Efforts to study this species' natural distribution, genetics, breeding, and cultivation have been hindered by the lack of a high-quality reference genome. To address this, we produced a hybrid high-quality reference genome of M. coruscus using a long-read platform to assemble the genome and short-read, high-quality technology to accurately correct for sequence errors. The genome was assembled into 10,484 scaffolds, a total length of 1.90 Gb, and a scaffold N50 of 898 kb. Ab initio annotation of the M. coruscus genome assembly identified a total of 42,684 genes. This accurate reference genome of M. coruscus provides an essential resource with the advantage of enabling the genome-scale selective breeding of M. coruscus. More importantly, it will also help in deciphering the speciation and local adaptation of the Mytilus species.
