The interplay between virus infection and water-related stress is mediated by the plant metabolism of ascorbic acid. [PDF]
Summary Plants are often subjected to environmental variations in the context of infection such that virus‐induced and abiotic stresses co‐occur. One such environmental variation is water stress, which strongly impacts plant fitness. Although there is ample evidence of the beneficial effects of plant viruses under drought, the consequences of infection
