In potato tubers, Kunitz-type proteinase inhibitors are part of major storage proteins, and consist of several members of the 22 kDa protein family. Southern blot analysis suggested that PKPI genes might compose a small multigene family. By using in vitro tuberization system, accumulation of PKPI mRNA was specifically detected in tubers from early days of the development, and thus expected to be used as a molecular marker of potato tuber development
