摘要/Abstract

摘要：

黄龙病菌为韧皮部杆菌，属难培养细菌，至今无法分离并进行人工继代培养，柑橘生产中尚无有效根治措施，也无可利用的抗病品种。本文中就黄龙病菌及其致病机制、柑橘抗（耐）黄龙病机制与抗病资源发掘等方面，综述柑橘黄龙病菌与寄主互作的分子机制研究进展，基于基因编辑等分子辅助育种技术对柑橘抗病育种进程提出展望，为后续深入解析黄龙病致病机理及抗性育种提供理论参考和基因资源信息。

Abstract:

Candidatus Liberibacter is a phloem-colonizing gram-negative bacterium，which is yet to be isolated and cultured in vitro. There are currently no effective remedies and no commercially available citrus varieties that are resistant to HLB. In this review，the research progress on the molecular mechanism of the interaction between Candidatus Liberibacter and citrus was reviewed from the aspects of HLB and its pathogenic mechanism，citrus resistance（tolerance）HLB mechanism and disease resistance resource discovery. Based on molecular-assisted breeding techniques such as gene editing，the process of citrus disease resistance breeding was prospected，which provided theoretical reference and gene resource information for further analysis of the pathogenic mechanism of HLB and resistance breeding.

Key words: citrus, Huanglongbing, pathogen-host interactions, disease resistance breeding
