Elevated Atmospheric CO₂ Concentrations Reduce Tomato Mosaic Virus Severity in Tomato Plants.

ABSTRACT: Tomato mosaic disease, caused by tomato mosaic virus (ToMV), was studied under naturally elevated [CO₂] concentrations to simulate the potential impacts of future climate scenarios on the ToMV-tomato pathosystem. Tomato plants infected with ToMV were cultivated under two distinct [CO₂] environments: elevated [CO₂] (naturally enriched to approximately 1000 μmol mol^-1) and ambient [CO₂] (ambient atmospheric [CO₂] of 420 μmol mol^-1). Key parameters, including phytopathological (disease index, ToMV gene expression), growth-related (plant height, leaf area), and physiological traits (chlorophyll content, flavonoid levels, nitrogen balance index), were monitored to assess the effects of elevated [CO₂].
