摘要(Abstract)：

植原体是一类无细胞壁、不能人工培养、存在于植物筛管内的专性寄生菌,世界各地已报道植原体可引起1 000余种各类植物系统性病害,涵盖农作物、园艺、花卉、果树和林木等,该病害传播性强、症状明显、危害较大,可不同程度引起植物生长发育异常或变异,甚至造成植株死亡。樱桃植原体病害就是其中一种,近年来该病害已经成为威胁樱桃产业发展最为重要的病害之一,主要引起樱桃花变叶(绿)及花器官、叶片、果实的生长发育异常和变异,并最终导致植株2～5 a(年)内迅速死亡,对我国乃至世界樱桃产业造成了非常重大的损失。随着我国近几年不同地区樱桃植原体病害发生面积、规模及危害程度地不断增加,尤其是笔者研究发现的重庆地区大规模爆发引起了极大威胁,使得有关其致病机制、植株生长发育特性及防治方法的系统研究显得迫在眉捷、尤为重要。针对樱桃植原体病害研究的需求,笔者综述了国内外有关研究进展,主要从植原体的分类、检测与传播以及樱桃植原体病害等多个方面进行阐述,为进一步开展樱桃植原体病害研究与防治等提供重要基础,并对未来的研究前景与应用价值进行了分析。
