丁香假单胞菌的分子生物学研究进展

Research Advancement of Molecular Biology in Pseudomonas syringae

丁香假单胞菌是好氧、腐生性强的革兰氏阴性菌,所引起的植物病害发生率位居十大细菌性植物病害之首,尤其引发的疫病在各农业大国爆发并有在世界范围扩散的趋势,给各国农业生产造成巨大的经济损失。基于国内外学者最新的分子生物学研究报道,对丁香假单胞菌的致病变种、病原菌鉴定、植物检疫、早期快速检测技术、致病机制及生物防治等方面进行综述,并探讨现阶段该病害研究存在的问题以及未来的研究方向与防治方案。

Pseudomonas syringae is an aerobic and strong saprophytic Gram-negative bacteria,the occurrence rate of its plant disease rankes first in the ten major bacterial plant diseases,the blight outbreaks in large-agricultural countries, there is a tendency to spread across the world, and it caused huge economic losses to agriculture country. Based on the latest research on molecular biology, this study summarized pathogenic variants of Pseudomonas syringae, pathogenic bacteria identification, early rapid detection technology,pathogenic molecular mechanism and biological control, etc. of Pseudomonas syringae,and discussed the problems existing at the recent research, research directions and preven- tion in the future as well as control programs of the blight.
