Abstract: Two DNA fragments, promoter (fragment 1) and promoter with signal peptide-coding sequence (fragment 2) of sporamin from sweet potato Nahshu 88, a widely cultivated variety in China, were amplified by the polymerase chain reaction (PCR). The amplified fragments were cloned and then sequenced. Sequenc
