新型植物免疫激活蛋白维大力(VDAL)对烟草花叶病毒抑制作用
Inhibitory Effect of Novel Plant Immune Activating Protein VDAL on Tobacco Mosaic Virus
摘要
Abstract
[Objective]To clarify the inhibitory effect of a new plant immune activating protein(VDAL)on tobacco mosaic virus(TMV).[Method]The inhibition of plant immune activating protein(VDAL)on TMV and the effect on peroxidase(POD)activity in tobacco plants were determined by spot inhibition and spectrophotometry.[Result]VDAL had a good inactivation effect on TMV in vitro.When the inactiva-tion time was 90 min,the inhibition rate of lesions could reach 80.76%.After three times of spraying,the inhibition rate could rise to 85.04%,and the peroxidase activity increased 1.26 times compared with the control.[Conclusion]VDAL may control TMV disease by inactivating the virus and inducing the defense response of tobacco plants.关键词
