IbMADS1 (Ipomoea batatas MADS-box 1 gene) is Involved in Tuberous Root Initiation in Sweet Potato (Ipomoea batatas)

摘要

Background and AimsThe tuberization mechanism of sweet potato (Ipomoea batatas) has long been studied using various approaches. Morphological data have revealed that the tuberizing events result from the activation of the cambium, followed by cell proliferation. However, uncertainties still remain regarding the regulators participating in this signal-transduction pathway. An attempt was made to characterize the role of one MADS-box transcription factor, which was preferentially expressed in sweet potato roots at the early tuberization stage.
