摘要： Angelica sinensis is a perennial herbaceous species mainly cultivated in the Gansu, Yunnan, and Qinghai provinces of China, and its dried roots have been widely used for nourishing blood and harmonizing vital energy, largely relying on its bioactive compounds (e.g., alkylphthalides, polysaccharides, and flavonoids). In recent years, viral diseases have been suspected to be present in A. sinensis in field cultivation. In order to reveal the infection status and causes, a survey and the identification of viral diseases and their influence on the yield and quality of A. sinensis were conducted in four different counties of Gansu province. The results showed viral disease rates of ca. 21% to 37% for potato virus Y (PVY) and tomato mosaic virus (ToMV), as well as ca. 2.8- to 8.9-fold decreases in root yield on a unit-area basis; meanwhile, the contents of the main bioactive compounds (i.e., ferulic acid, ligustilide, and polysaccharides) were significantly lower in the virus-infected plants (VIPs) compared with the virus-free plants (VFPs); there were significant positive relationships of the viral disease rate with planting density and expression levels of the PVY-coat protein (CP) and ToMV-CP genes (p < 0.01). The above-mentioned observations indicate that it is necessary and urgent to take measures (e.g., controlling plant density, rational rotation, and using virus-free seedlings) to prevent the spread of plant viruses.
