The Contrasting Effects of Elevated CO₂ on TYLCV Infection of Tomato Genotypes with and without the Resistance Gene, Mi-1.2.

ABSTRACT: Elevated atmospheric CO₂ typically enhances photosynthesis of C3 plants and alters primary and secondary metabolites in plant tissue. By modifying the defensive signaling pathways in host plants, elevated CO₂ could potentially affect the interactions between plants, viruses, and insects that vector viruses. R gene-mediated resistance in plants represents an efficient and highly specific defense against pathogens and herbivorous insects. The current study determined the effect of elevated CO₂ on tomato plants with and without the nematode resistance gene Mi-1.2, which also confers resistance to some sap-sucking insects including whitefly, Bemisia tabaci. Furthermore, the subsequent effects of elevated CO₂ on the performance of
