Abstract

A partial alpha-amylase cDNA was isolated from red porgy (Pagrus pagrus, Teleostei: Sparidae) and its tissue specific expression during larval development was examined. The cDNA was 949 bp long and showed 90% identity with other fish amylases. A 545 bp fragment was used to study amylase expression using in situ hybridization and RT-PCR techniques. Both methods showed a similar pattern: high and relatively constant expression for the first 30 days after hatching (dah), subsequently decreasing until the end of the experiment at 60 dah. The goal of this work was to extend the existing knowledge of the functionality of larval fish digestive systems and to provide new information about alpha-amylase gene expression.
