Antagonism or synergism between papaya ringspot virus and papaya mosaic virus in Carica papaya is determined by their order of infection
چکیده انگلیسی
Antagonism between unrelated plant viruses has not been thoroughly described. Our studies show that two unrelated viruses, papaya ringspot virus (PRSV) and papaya mosaic virus (PapMV) produce different symptomatic outcomes during mixed infection depending on the inoculation order. Synergism occurs in plants infected first with PRSV or in plants infected simultaneously with PRSV and PapMV, and antagonism occurs in plants infected first with PapMV and later inoculated with PRSV. During antagonism, elevated pathogenesis-related (PR-1) gene expression and increased reactive oxygen species production indicated the establishment of a host defense resulting in the reduction in PRSV titers. Polyribosomal fractioning showed that PRSV affects translation of cellular eEF1α, PR-1, β-tubulin, and PapMV RNAs in planta, suggesting that its infection could be related to an imbalance in the translation machinery. Our data suggest that primary PapMV infection activates a defense response against PRSV and establishes a protective relationship with the papaya host.
