基于柑橘寄主及环境的黄龙病相关研究进展

Research Progress of Candidatus Liberibacter asiaticus Based on Citrus Host and Environment

柑橘黄龙病是一种毁灭性的病害,流行于世界大多数柑橘产区,造成严重经济损失。目前对黄龙病的病源、传播媒介及防控等方面已进行了广泛研究,但黄龙病目前仍难以有效防治。该文以柑橘寄主为主要线索,综述了目前发现的一些耐病性较好的柑橘种质、在植物自身免疫反应中起关键作用的转录因子和基因表达、脱毒苗木在黄龙病防控上的重要性、黄龙病与根际微生物和土壤理化性质相互影响、科学栽培对黄龙病传播的抑制作用及果园地理位置通过影响木虱的活动来影响黄龙病流行等方面的研究进展,为开展黄龙病防控的相关研究提供参考。

Candidatus Liberibacter asiaticus CLas is a devastating disease that is prevalent in most citrus producing areas in the world, causing serious economic losses. At present, extensive research has been conducted on the source, vector, prevention and control of CLas,but the disease has not yet been controlled effectively. Taking citrus host as the main clue,this article summarizes the research progress on some new discovered citrus germplasm with good disease tolerance,transcription factors and gene expression that play a key role in plant autoimmune response,and the important role of virus-free seedlings in the prevention and control of CLas,the interaction of rhizosphere microorganisms and soil physical and chemical properties,the inhibitory effect of scientific cultivation on the spread of CLas,and the influence of the geographical location of orchard on the spread of CLas by affecting the activities of psyllids,providing a reference for the research on control of CLas.
