physiological function | chemical compounds that generate reactive oxygen species or directly applied hydrogen peroxide (H2O2) are able to induce hypersensitive response-type necroses in tobacco mosaic virus-inoculated Xanthi-nc tobacco even at high temperatures (e.g. 30°C). Activity of dehydroascorbate reductase is significantly higher at 30°C, as compared with 20°C, suggesting that DHAR might contribute to the inhibition of hypersensitive response-type necroses at 30°C | Nicotiana tabacum |
