摘要: 综述病原体与植物相互作用形成瘿瘤的最新进展,重点介绍细菌、真菌、原生动物、昆虫及线虫等5类生物诱导植物瘿瘤形成的致病机制及影响因子,分析植物细胞向瘿瘤生长的共同原因——植物激素平衡的紊乱和分化细胞获得分生组织特征,讨论一些病原体通过分泌效应蛋白操纵植物发育,以牺牲植物的生长和繁殖为代价使自身受益并诱发瘿瘤形成,对今后的研究方向作出展望。

关键词: 植物瘿瘤, 病原体, 植物激素, 效应蛋白

Abstract: The recent advances of pathogen-plant interactions to form galls are reviewed, which focuses on pathogenesis and influencing factors of gall formation of bacteria, fungi, protozoa, insects and nematodes. The disturbance of the phytohormonal balance and the acquisition of meristematic characteristics by differentiated cells are shared causes of gall formation in host plants. Some pathogens manipulate host plant development by secreting effector proteins, benefiting themselves at the expense of the plant growth and reproduction, which results in the formation of galls. Further research fields are suggested.

Key words: plant gall, pathogen, phytohormone, effector proteins
