Lower incidence and severity of tomato virus in elevated CO2 is accompanied by modulated plant induced defence in tomato

Abstract: Elevation in atmospheric CO(2) concentration broadly affects plant phenology and physiology, and these effects may alter the performance of plant viruses. The effects of elevated CO(2) on the susceptibility of tomato plants to Tomato yellow leaf curl virus (TYLCV) were examined for two successive years in open top chambers (OTC) in the field. We experimentally tested the hypothesis that elevated CO(2) would reduce the incidence and severity of TYLCV on tomato by altering plant defence strategies. Our result… Show more

“…Hence, overexpression of the JA-associated gene may be related to insect feeding rather than to virus infection per se. Moreover, combined applications of exogenous SA and JA induced stronger resistance to TYLCV than the application of either SA or JA alone (Huang et al, 2012). Therefore, it appears that the modulated interaction between SA and JA in the R line may significantly contribute to the observed TYLCV resistance.…”

“…Resistance to biotic stress is strongly associated with homeostasis of hormones such as SA and JA (Glazebrook, 2005;Thaler et al, 2010). Tomato plants grown in a CO 2 -enriched atmosphere exhibited increased resistance to the begomovirus TYLCV, as well as increased SA levels (Huang et al, 2012). Infection of Arabidopsis plants with the begomovirus Cabbage leaf curl virus (CaLCuV) led to an early pathogen response involving the SA pathway (Ascencio-Ibáñez et al, 2008).…”
