Viroids and Diseases of Unknown Etiology, U.S.-India Seminarand Workshop, November 18-26, 1989, New Delhi, India, Award in Indian and U.S. Currencies

说明：本项目支持10名美国科学家参加将于1989年11月15日至28日在印度新德里举行的关于类病毒和病因不明疾病的美印研讨会。印度合作科学家是国际林业研究组织病毒和支原体疾病联盟主席S. P. Raychaudhuri博士。目标包括交流关于分离和鉴定与热带植物疾病有关的类病毒的新技术的信息，以及对其中一些技术在不确定病因的疾病上进行试验。与会者预计将确定哪些领域的合作研究将有利于美国和印度。范围：本次研讨会的美国和印度主任在植物病害和微生物学研究方面处于世界领先地位。美国现有的类病毒及其特性的专业知识和技术将受益于将其应用于已知发生在印度的类病毒疾病，如马铃薯纺锤块茎、柑橘外皮病和其他没有确定病因的疾病。其中一些疾病如果传播到美国，在经济上可能具有重大意义。因此，在这一领域的合作研究和信息交流将对两国的科学和农业工业有价值。

Description: This project supports participation by ten U.S. scientists in an U. S.-India seminar-workshop on viroids and diseases of uncertain etiology, to be held in New Delhi, India November 15-28, 1989. The Indian cooperating scientist is Dr. S. P. Raychaudhuri, Chairman of the International Union of Forestry Research Organization-Virus and Mycoplasma Diseases. The objectives include exchange of information on new techniques for isolating and characterizing viroids associated with diseases of tropical plants, and the testing of some of these techniques on diseases of uncertain etiology. The participants are expected to identify areas where cooperative research would be beneficial to the U.S. and India. Scope: The U. S. and Indian directors of this seminar-workshop are among world leaders in the study of plant diseases in particular, and microbiology in general. The expertise and techniques available in the U. S. of viroids and their characteristics would benefit and be sharpened from applications to viroid diseases known to occur in India, such as potato spindle tuber, citrus exocortis and other diseases for which no certain cause is identified. Some of these diseases can be economically significant if transmitted to the U. S. Thus cooperative research and exchange of information in this field will be of value to science and to the agricultural industry in the two countries.
