图3 突变体ΔFgAbp1对杀菌剂氰烯菌酯的敏感性 a：PH-1、ΔFgAbp1和ΔFgAbp1-C在含有0.5 μg·mL-1氰烯菌酯的PDA中25℃培养3 d的生长比较。溶剂DMSO作为对照组Comparison of PH-1, ΔFgAbp1 and ΔFgAbp1-C following incubation at 25℃ for 3 days on PDA plates supplemented 0.5 μg·mL -1 phenamacril. DMSO was used as a control treatment;b：各菌株在0.5 μg·mL -1氰烯菌酯处理下的生长抑制率。误差线表示标准差,**：P<0.01 The growth inhibition rate of each strain under 0.5 μg·mL-1 phenamacril treatment. Error bars represent standard deviation;c：氰烯菌酯对PH-1、ΔFgAbp1和ΔFgAbp1-C分生孢子萌发的抑制作用。激光共聚焦显微镜拍摄微分干涉（DIC）和荧光增白剂（CFW）染色照片。标尺50 μm Inhibitory effect of 0.5 μg·mL-1 phenamacril on conidial germination of PH-1, ΔFgAbp1 and ΔFgAbp1-C. Differential interference contrast (DIC) images of conidia stained with calcofluor white (CFW) were taken with a confocal fluorescence microscope. Bar = 50 μm;d：0.5 μg·mL -1氰烯菌酯处理下各菌株分生孢子的萌发率。误差线表示标准差**：P<0.01 The conidial germination rate of each strain under 0.5 μg·mL-1 phenamacril treatment. Error bars represent standard deviation
