中国植原体病害的状况、分布及多样性研究进展
摘要：
植原体是引起众多植物病害的一类重要原核致病菌，能引起许多重要粮食作物、蔬菜、果树、观赏植物和林木严重病害，造成巨大损失。为了深入了解中国植原体病害的状况、分布及多样性，最终实现植原体病害的科学防控，归纳总结了中国植原体病害的研究历史、经济重要性、症状特点、流行传播、鉴定方法、地域分布及多样性等。提出了今后应从抗性资源筛选、抗病基因鉴定，基因组特征、致病机理、病害流行学、防治方法和昆虫传毒机理等方面开展植原体病害研究的建议。

Abstract:
Phytoplasmas are important prokaryotic pathogenic bacteria of many plant diseases, and can cause serious diseases in important food crops, vegetables, fruit trees, ornamental plants and trees, resulting in huge economic losses. In order to deeply understand the status, distribution and diversity of phytoplasma diseases in China and scientifically control phytoplasma diseases, this paper summarizes the research history, economic importance, symptom characteristics, epidemic and transmission, identification methods, geographical distribution and diversity of phytoplasma diseases in China. It is suggested that the research on phytoplasma diseases should be carried out from the aspects of screening resistant resources, identifying resistant genes, genome characteristics, pathogenic mechanism, disease epidemiology, control methods and mechanism of insect vector transmission.
Key words: China, phytoplasma disease, geographical distribution, genetic diversity, pathogen identification
