Papaya ringspot potyvirus (PRSV) is rapidly transmitted by a number of aphid species and causes the most serious virus disease of papaya worldwide. This article reviews research to develop transgenic papaya using ’pathogen-derived resistance’, transforming plants with a pathogen’s gene. A papaya transformation system was developed and a promising transgenic papaya line was identified.
