UV-B radiation modifies the acclimation processes to drought or cadmium in wheat.

Highlights: [•] UV-B has different impact on drought and Cd stress responses. [•] Protective effect of UV-B against drought may be in relation with salicylic acid. [•] UV-B specifically influences drought or Cd-induced antioxidant/polyamine responses. [•] Changes in ortho-hydroxy-cinnamic acid content are also UV-B dependent. [ABSTRACT FROM AUTHOR]
