Title: SxtA gene sequence analysis of dinoflagellate Alexandrium minutum
Abstract: The dinoflagellate Alexandrium minutum is typically known for the production of potent neurotoxins such as saxitoxin, affecting the health of human seafood consumers via paralytic shellfish poisoning (PSP). These phenomena is related to the harmful algal blooms (HABs) that is believed to be influenced by environmental and nutritional factors. Previous study has revealed that SxtA gene is a starting gene that involved in the saxitoxin production pathway. The aim of this study was to analyse the sequence of the sxtA gene in A. minutum. The dinoflagellates culture was cultured at temperature 26°C with 16:8-hour light:dark photocycle. After the samples were harvested, RNA was extracted, complementary DNA (cDNA) was synthesised and amplified by polymerase chain reaction (PCR). The PCR products were then purified and cloned before sequenced. The SxtA sequence obtained was then analyzed in order to identify the presence of SxtA gene in Alexandrium minutum.
