Chickpea plants with severe yellowing and tip wilting were observed in the Cap-Bon Region of Tunisia in 2006. The viral-like symptoms resulted in yield loss of approximately 25% in some fields. A total of 110 symptomatic chickpea plants was collected from nine chickpea fields and tested at the Virology Laboratory of ICARDA, Syria for eight legume viruses using tissue-blot immunoassay (TBI...... hiện toàn bộ
Fumigation of Fruit with Short-Chain Organic Acids to Reduce the Potential of Postharvest DecayPlant Disease - Tập 82 Số 6 - Trang 689-693 - 1998
P. L. Sholberg
Vapors of acetic (1.9 or 2.5 μl/liter), formic (1.2 μl/liter), and propionic (2.5 μl/liter) acids were tested for postharvest decay control on 8 cherry, 14 pome, and 3 citrus fruit cultivars. Surfacesterilized fruit were inoculated with known fungal pathogens by drying 20-μl drops of spore suspension on marked locations on each fruit, placing at 10°C to equilibrate for approximately 24 h,...... hiện toàn bộ
Phylogenetic and Pathogenic Analyses Show That the Causal Agent of Apple Ring Rot in China Is Botryosphaeria dothideaPlant Disease - Tập 96 Số 4 - Trang 486-496 - 2012
Wei Tang, Zaisong Ding, Zhigang Zhou, Y. Z. Wang, Liyun Guo
Apple ring rot and Botryosphaeria canker are severe diseases affecting apple production in China, but there is confusion regarding which pathogens cause these diseases and their similarity to other diseases, such as white rot of apple, and ring rot and Botryosphaeria canker of pear. In this study, the pathogen of apple ring rot in China was compared with the pathogen of apple ring rot in ...... hiện toàn bộ
Triticum mosaic virus: A New Virus Isolated from Wheat in KansasPlant Disease - Tập 92 Số 5 - Trang 808-817 - 2008

In 2006, a mechanically-transmissible and previously uncharacterized virus was isolated in Kansas from wheat plants with mosaic symptoms. The physiochemical properties of the virus were examined by purification on cesium chloride density gradients, electron microscopy, sodium dodecyl sulfate polyacrylamide gel electrophoresis (SDS-PAGE), sequencing of the nucleotides and amino acids of th...... hiện toàn bộ
Differential Transmission of Isolates of the High Plains virus by Different Sources of Wheat Curl MitesPlant Disease - Tập 86 Số 2 - Trang 138-142 - 2002
Dallas L. Seifers, T. L. Harvey, Raymond Louie, Donald T. Gordon, T. J. Martin
High Plains virus (HPV) isolates from Colorado, Idaho, Kansas, Texas, and Utah were serologically related, had similar relative molecular masses (sodium dodecyl sulfate-polyacrylamide gel electrophoresis) for the 32-kDa diagnostic HPV protein, and were transmissible and maintained free of Wheat streak mosaic virus (WSMV) by vascular puncture inoculation. Collections of wheat curl mites (A...... hiện toàn bộ
