Using a large number of published DNA / RNA sequences, such as EST sequences, microsatellite DNA sequences of this species were obtained. The results show that EST contains abundant microsatellite sequences (about 2% -4%), and some species even reach more than 10% (such as catfish). Serapion et al. From the 43,033 EST sequences published by catfish (ichthyurus punctatus), 4,855 fragments containing microsatellites were screened. Zhan et al. 19 polymorphic microsatellite markers were successfully screened from the EST library of scallop scallops. A large number of experiments have shown that using data in public databases for secondary use is a fast, effective, and inexpensive method for obtaining new microsatellite marks.
