To date, the cultivation of unauthorized GM papaya resistant
to PRSV-YK has not been allowed by the Cartagena Protocol, an
international agreement regulating the international movement of
GMorganisms. Thus, the cultivation and use of GM papaya resistant
to PRSV-YK as food has been limited, and it cannot be imported into
Japan (MAFF, 2011; MHLW, 2011).
