Engineered Mild Strains of Papaya ringspot virus for Broader Cross Protection in Cucurbits

BJ You, CH Chiang, LF Chen, WC Su… - Phytopathology, 2005 - Am Phytopath Society
Papaya ringspot virus (PRSV) HA5-1, a mild mutant of type P Hawaii severe strain (PRSV P-
HA), has been widely used for the control of PRSV type P strains in papaya, but did not
provide practical protection against PRSV type W strains in cucurbits. In order to widen the
protection effectiveness against W strains, chimeric mild strains were constructed from HA5-
1 to carry the heterologous 3′ genomic region of a type W strain W-CI. Virus accumulation
of recombinants and their crossprotection effectiveness against W-CI and P-HA were …
