Conteúdo: | The coat protein (CP) gene of a Taiwan strain of papaya ringspot virus (PRSV) was efficiently transferref to papaya by Agrobacterium-mediated transformation, assisted by wounding of embryogenic tissues derived from immature zygotic embryyos with carborundum in liquid phase. Thirty-eight transgenic lines were micropropagated by tissue culture and their resistance to PRSV was evaluated by mechanical inoculation with the virus under greenhouse conditions. Among them, 9 lines were found highly resistant to PRSV and 8 lines moderately resistant. The highly resistant lines also conferred broadspectrum resistance to PRSV strains from Thailand and Hawaii.
