Abstract Grapevine is an economically important crop, affected by major production losses due to high virus prevalence. Arbuscular mycorrhizal fungi (AMF) can reduce the impact of plant biotic stresses. However, hormonal response simultaneous presence viruses and AMF remains largely unknown. In this study, we explored potential modify grapevine's defense compatible infections. We used GRSPaV, GLRaV‐3, GPGV as infectious viral agents, separately or in different combinations. Two inoculums were tested for their bioprotective abilities, RHIZ ( Rhizophagus irregularis) MIX R. irregularis , Funneliformis mosseae F. caledonium ). Generally, induced stronger physiological responses than inoculum, especially during earlier phase symbiosis. The main findings connected profile grapevine infected all three inoculated with MIX. particular, salicylic acid (SA) abscisic (ABA) concentrations five fifteen months post inoculation, respectively. Expressions VvNCED1 VvBG1 up‐regulated uninoculated grapevines, indicating slower induction stress mechanisms. Parameters related vigour growth at both time points, regardless combination. conclusion, defense‐like grapevines multiple characterized ABA SA, accompanied a consistent enhancement vigor parameters. This study confirms symbiosis potentially promising additional tool combating diseases vineyards.
