Viral infections are major contributors to crop yield loss and represent a significant threat sustainable agriculture. Plants respond virus attacks by activating sophisticated signalling cascades that initiate multiple defence mechanisms. Notably, several phytohormones, including salicylic acid (SA), jasmonic (JA), abscisic (ABA), ethylene (ET), known shape these responses. In recent years, various plant growth regulators (PGRs) such as melatonin, carrageenans, sulfated fucan oligosaccharides, nitric oxide (NO), brassinosteroids (BRs), hydrogen sulfide (H2S) have also emerged crucial of responses against infections. Emerging evidence indicates PGRs coordinate with phytohormones activate strategies, (1) stomatal closure limit pathogen entry, (2) callose deposition block plasmodesmata restrict viral spread within host tissues, (3) attenuation replication, (4) activation RNA interference (RNAi), antiviral response. However, the interactions crosstalk between remain largely underexplored, thereby limiting our ability develop innovative strategies for managing diseases. This review discusses diverse functions among in orchestrating mechanisms, highlighting their impact on movement, intercellular transport.
