Our research aimed to isolate and sequence the SOD gene from the genomic DNA of Scylla serrata and Scylla olivacea and to study its phylogeny.
In crustaceans, superoxide dismutase (SOD) serves as the first line of defense against stress. Extracellular Cu/Zn-SOD has been demonstrated in several investigations involving crustaceans. Crustaceans do not have a distinct immune system. They entirely depend on the innate immune system triggered when they come in contact with any pathogen.
Partial SOD gene was isolated from the genomic DNA of S. serrata and S. olivacea through polymerase chain reaction.
We successfully isolated partial SOD genes of 942bp and 957bp from S. serrata and S. olivacea, respectively. The sequences were submitted to the NCBI GenBank database.
The phylogenetic study suggests their clustering with the genus Scylla species. Investigating the SOD gene sequences across diverse crustacean lineages can reveal profound insights into their evolutionary history and the intricate relationships among species concerning their SOD development.
This research holds the potential to enhance our understanding of the evolutionary adaptations that have shaped these organisms.
