The virus can cause deformation and ringspot symptoms on the fruit, hence the name PRSV. Commercial PRSV-resistant transgenic papaya expressing the coat protein (CP) gene of the virus has been used to control PRSV P in Hawaii, as will be discussed later.Figure 1.ork in the 1980s showed that the aphid-transmitted papaya mosaic virus and PRSV were really the same, and the name of PRSV was adopted. PRSV is a member of the family Potyviridae, a large and arguably the most economically important group of plant viruses.
