醌外部抑制剂（QoI）是强效杀真菌剂，除了它们的杀真菌剂活性之外，已经报道它们增加植物激活细胞防御反应的能力并促进植物生长。在这项工作中，QoI类杀菌剂吡唑醚菌酯对黄瓜花叶病毒（CMV），马铃薯Y病毒（PVY）和假单胞菌pv。在用病原体人工接种植物后，番茄植株中的番茄。在受控的环境条件下，吡唑醚菌酯延迟病毒和细菌疾病的发展，即使P.番茄内部群体水平没有受到显著影响。相比之下，在商业温室的田间条件下，整个番茄栽培期间记录到CMV病发病率降低。基因表达分析表明，吡唑醚菌酯的应用对番茄MAPKs转录水平的影响，并可能干扰植物的胁迫反应。
Quinone outside inhibitors (QoI) are powerful fungicides, which have been reported, additionally to their fungicide activity, to increase plant capacity to activate cellular defense responses and to promote plant growth. In this work, the effect of the QoI class fungicide pyraclostrobin was examined against Cucumber mosaic virus (CMV), Potato virus Y (PVY) and Pseudomonas syringae pv. tomato in tomato plants following artificial inoculation of the plants with the pathogens. Under controlled environmental conditions, pyraclostrobin delayed viral and bacterial disease development, even if P. syringae pv. tomato internal population levels were not affected significantly. In contrast, under field conditions in commercial greenhouses, a reduced CMV disease incidence throughout the tomato cultivation period was recorded. Gene expression analysis indicated an effect of pyraclostrobin application on tomato MAPKs transcript levels and a possible interference with plant stress responses.
