梨疱状溃疡类病毒研究进展

Research progress of Pear blister canker viroid

梨疱状溃疡类病毒(Pear blister canker viroid,PBCVd)危害仁果、核果类果树,是我国进境植物检疫性有害生物。伴随近年来梨树种植业逐渐趋于产业化和规模化的发展,PBCVd成为梨树种植业健康发展的重要威胁。由于产业发展的需要,梨树繁殖材料的引入也日益频繁,进一步增加了PBCVd传播和扩散的风险。提高对PBCVd的认识,有助于有效防控PBCVd引起的灾害。本文详细介绍了PBCVd的发现及鉴定、生物学及分子生物学特征,对PBCVd的检测方法进行综述,针对今后PBCVd的防控提出建议,展望了今后的相关研究。

Pear blister canker viroid （PBCVd） infects pome and stone fi＇uits and causes severe diseases in some sensitive hosts. PBCVd has been included in entry plant quarantine pest list. As large scale and industrialization of pear planting industry are increasing in recent years in China, PBCVd becomes an important threat to healthy development of pear industry. Moreover, import of more propagative materials from other countries because of the increasing demands of development of pear industry increases the risk of transmission and spread of PBCVd. Improving understand of PBCVd will be helpful to control diseases induced by PBCVd. Thus, this paper described the detailed progress of discovery and identification of PBCVd and its biological and molecular characteristics, revised detection methods using for PBCVd and supply some suggestions for controlling PBCVd, and prospect relavent research in the future.
