Virus-induced tolerance to abiotic stress. A. Induction of tolerance to abiotic stress has been described in plant-virus interactions involving different genera of RNA (+) viruses and, at least, one ssDNA virus. B. Viral-induced tolerance has been analyzed in the usual experimental hosts Nicotiana benthamina, Arabidopsis thaliana, and tomato, and in many crop species. C. The occurrence of different abiotic stresses (heat, drought, salt), considered individually or combined, result in a reduction of the soil water potential (Ψs), temperatures exceeding the optimal limits for the vegetative and reproductive growth (↑T), and higher oxidative potential (ROS). D. Under these challenging environmental conditions, virus-infected plants exhibit and array of virus-induced responses which mainly result in i) a reduction of the plant water potential (Ψp) below Ψs, allowing for an easier water uptake, and in ii) a better capacity to manage with the oxidative stress, among others; bold letters denote beneficial responses described for most of the plant-virus interactions analyzed to date.
