초록

Several hypotheses for the origin of cultivated sweetpotato [Ipomoea batatas L. (Lam)] have been suggested but the exact progenitor is still unknown. Based on the results of RFLP patterns, microsatellite markers, SNP markers, FISH analyses, and genome analyses of haplotypes, wild species belonging to batatas group, I. trifida, I. leucantha, I. littoralis, I. tabascana, I. tenuissima, I. tiliacea, and I. triloba have been suggested as a progenitor. However, recently, advanced genomic technologies and characterization of the inserted T-DNA fragments of Agrobacterium in the genome of cultivated sweetpotato and wild species through horizontal gene transfer suggest that there may be an older progenitor than the wild species suggested so far. ?
