摘要
The structure gene for ferredoxin, petFI, from Anabaena siamensis has been ampli-fied by polymerase chain reaction(PCR) and cloned into cloning vector pGEM-3zf(+). The nucleotidesequence of petFI has been determined with silver staining sequencing method. There is 96. 8% homologybetween coding region of petFI from A. siamensis and that of petFI from A. sp. 7120. Amino acid se-quences of seven strains of blue-green algae are compared.
