been deduced on the basis of their expression pattern (Kim et al., 2002, 2005; Lalusin et al., 2006).Improvements in various molecular approaches have enabled the mining of genes involved in storage root development in sweetpotato, resulting in the identification of a number of genes that are differentially expressed in developing storage roots (You et al., 2003; Tanaka et al., 2005). Based on the results of their comparison of the distribution of KNOX1 gene expression and endogenous trans-zeatin riboside (t-ZR) in sweetpotato roots, Tanaka et al. (2008) suggested three sweetpotato class 1 knotted1-like homeobox (KNOX1) genes as possible regulators of cytokinin levels in storage roots. Ku et al. (2008) recently isolated IbMADS1 from sweetpotato and analysed its functional role in storage root development using potato overexpressing IbMADS1. However, to date, due to the
