Description
Summary:Epinephelus sexfasciatlls (six bar grouper) is a reef-associated species that often known as seafood delicacy in Asian countries. This fish is well-distributed across western Pacific region. Limited molecular data is available for this species, but none came from Malaysia.This study is aimed to sequence COl gene from genus Epinephellls ESM03 followed by determination of the genetic divergence values and phylogenetic analysis. This study involved total genomic DNA extraction, optical density reading, agarose gel electrophoresis, polymerase chain reaction and DNA sequencing as well as data analysis. A total of 496 bp of COl gene from grouper ESM03 had been successfully sequenced and it matched 99% with E. sexfasciatus KC959953.1. Results obtained from this gene showed that there are mutations present in certain base. Pairwise genetic divergence analysis revealed that there is 2.6% of difference between grouper ESM03 and E. sexfasciatus KC959953.l. The phylogenetic trees constructed showed that genus Epinephellis is monophyletic.
