Conteúdo: | Papaya ringspot virus (PRSV) is the main phytossanitary problem in papaya crop. It is responsible for migration of papaya production region in Brazil from São Paulo to Bahia and Espírito Santo. PRSV causes high losses in production due to direct damages and to the eradication of infected plants. The virus is aphid-transmitted in a non-persistent manner, which makes the chemical control of the vector ineffective. The development of PRSV resistant cultivars by conventional breeding is not possible because of the genetic barriers that prevent the transfer of resistant genes of other Caricaceae species into cultivated papaya. Several research groups in Brazil and worldwide unsuccessfully tested the preimunization approch with mild strains of PRSV-P. In the 90's, an Embrapa paternship with Cornell University began to develop a Sunrise Solo transgenic cultivar carrying part of the coat protein gene from one Brazilian PRSV-P strain.
