Abstract
A large-DNA-fragment library is necessary for research into the Porphyra genome. In this study, a bacterial artificial chromosome (BAC) library of Porphyra yezoensis was constructed and characterized. The library contains 54,144 BAC clones with an average insert size of about 65 kb and fewer than 0.7% of clones without large inserts. Therefore, its capacity is more than 6.6 P. yezoensis genome equivalents, and the probability of recovering any nuclear DNA sequence from the library is higher than 99%. The library shows good fidelity and stability. A putative trehalose-6-phosphate synthase (TPS) gene was successfully screened out from the library. The above results show that the library is useful for gene cloning and genomic research in P. yezoensis.
