Through a genomic project carried out during the past year, the company ADL Diagnostic Chile has for the first time managed to sequence the corvina drum (Cilus gilberti) genome, progress expected to speed up the technological development for farming this species.
Given the importance of aquaculture production diversification, ADL has been involved for four years as co-performer in the Chilean Aquaculture Diversification Program (PDACh) and its Complementary Technology Program (PTEC), led by Fundación Chile and co-financed by the Promotion of Production (CORFO), oriented to the development of intensive farming technology of the corvina drum.
The genomic and transcriptomic project developed by the ADL technical team concluded the functional annotation stage of the genes, that is, the constitution of the first draft that accounts for the identification of the genes responsible for the corvina drum physiology.
According to ADL, with this draft, it will be possible to start working on the analysis of the expression of genes using transcriptomic techniques in order to address and solve diverse gaps of productive and sanitary character in a better and more efficient way.
In addition, work has been performed on the generation of candidate microsatellites for inbreeding and kinship analysis, and in the conformation of a database of simple nucleotide variants, multiple nucleotide variants, insertions, deletions and structural variants. The purpose is to contribute to the genetic program developed by a team of genetics at the Faculty of Marine Sciences of the Universidad Católica del Norte (UCN), aimed at maintaining genetic diversity and developing highly adapted specimens to intensive farming, as it occurs with other productive species, SONAPESCA reported.
"In this way, it is expected that during 2017 the transcriptomy stages and the database of variants will be completed in order to begin the work on experimental designs that make it possible to solve the productive gaps identified so far, accelerating the advance in the technological development of the species farming," it was stressed at the aquaculture laboratory.
