Effect of UV-B priming on the abiotic stress tolerance of stress-sensitive rice seedlings: Priming imprints and cross-tolerance

Ultraviolet (UV)–B priming can boost the abiotic stress tolerance of plants by activating stress-responsive pathways. The main objective of the present study was to investigate the persistence of priming imprints and cross-tolerance inducing effects of UV-B priming in abiotic stress-sensitive rice (Oryza sativa L. ‘Aiswarya’) when subjected to various abiotic stressors (NaCl, PEG, and UV-B). The UV-B priming of rice seeds and seedlings...
