The complex process of formation of storage roots (SRs) from adventitious roots affects sweetpotato yield. Identifying the genes that are uniquely expressed in the SR forming cultivated species, Ipomoea batatas (Ib), and its immediate ancestral species, Ipomoea trifida (It), which does not form SRs, may provide insights into the molecular mechanisms underlying SR formation in sweetpotato. | Comparative analysis of the root transcriptomes of cultivated sweetpotato Ipomoea batatas L. Lam and its wild ancestor Ipomoea trifida Kunth G. Don
