title: PCR-based approach for sequencing mitochondrial genomes of decapod crustaceans, with a practical example from kuruma prawn (Marsupenaeus japonicus).
abstract: An approach for sequencing the entire mitochondrial genomes (mitogenomes) of decapod crustaceans using 79 newly designed and 7 published polymerase chain reaction (PCR) primers is described. The approach comprises the following steps: (1) the entire mitogenome is amplified in 2 or 3 long PCRs; (2) the 86 primers are used in different combinations to amplify contiguous, overlapping short segments of the entire mitogenome with the diluted long PCR products as templates; (3) direct cycle sequencing is conducted using the short PCR products. This strategy allows a more rapid determination of decapod mitogenomic sequences than a traditional method using cloned mitochondrial DNA and primer walking strategy. As a practical example, the mitogenomic sequence for a kuruma prawn Marsupenaeus japonicus (Crustacea: Decapoda), was determined using the PCR-based approach.
