A new, widespread disease was recently observed in soybean in the United States. The disease, named Soybean vein necrosis, is manifested by intraveinal chlorosis and necrosis, and has been found in almost all of the 50 fields visited over a period of 3 years in the midwest and midsouth part of the United States. A virus was isolated from symptomatic material, and detection protocols were developed. More than 150 symptomatic specimens collected from seven US States were tested, and all were found positive for the virus unlike 75 asymptomatic samples, revealing the absolute association between virus and disease. Protein pairwise comparisons coupled with phylogenetic analyses indicate that the virus is a new member of the genus Tospovirus.
最近在美国大豆中发现了一种新的广泛传播的病害。这种病害名为大豆叶脉坏死病,表现为叶脉间黄化和坏死,在美国中西部和中南部三年间走访的近50块田地中几乎都有发现。从有症状的材料中分离出一种病毒,并制定了检测方案。对从美国七个州收集的150多个有症状样本进行了检测,结果发现所有样本对该病毒均呈阳性,而75个无症状样本则不然,这揭示了病毒与病害之间的绝对关联。蛋白质成对比较及系统发育分析表明,该病毒是番茄斑萎病毒属的一个新成员。
