Emerging tospoviruses cause significant yield losses and quality reduction in vegetables, ornamentals, and legumes throughout the world. So far, eight tospoviruses were reported in China. Tomato fruits displaying necrotic and concentric ringspot symptoms were found in Guizhou province of southwest China. ELISA experiments showed that crude saps of the(More)
The virus isolate 2009-GZT, collected from tomato in Guizhou province of China, was identified as a new member of the genus Tospovirus based on its S RNA sequence. Because its provisional name, “tomato necrotic spot virus” (TNSV), was identical to an already existing member of the genus Ilarvirus, 2009-GZT was renamed “tomato necrotic spot-associated virus”(More)
Multi-hydroxyl amines including tris(hydroxymethyl)aminomethane (Tris), serinol and ethanolamine were selected as weak affinity ligands using a rapid screening by quartz crystal microbalance (QCM) biosensor. Based on the specific recognition between the ligands and two proteins, lysozyme (LZM) and cytochrome c (Cyt c), a weak affinity chromatography method(More)
Unlike chemical pesticides, antiviral plants are biodegradable, replenishable and safe. In this study, 14 sesquiterpene compounds from Tithonia diversifolia were tested for their activities against Tobacco mosaic virus (TMV) using the half-leaf method. Tagitinin C (Ses-2) and 1β-methoxydiversifolin-3-0-methyl ether (Ses-5) were found to have in vivo(More)
