植原体病害及其相关植物激素研究进展

Research on Phytoplasma Diseases and Related Plant Hormones

植原体(phytoplasma)是一类重要的植物细菌性病原,在世界范围内广泛分布,给林业、果树、经济作物等造成了巨大的危害。由于植原体不能体外培养,给研究带来了很多困难。目前,国内外通过对激素的检测研究其致病机理、生理生化特性等,对目前国内外感染植原体的植株内源激素(生长素、分裂素、赤霉素和脱落酸)的研究进展进行了综述。

Phytoplasmaisan is a kind of important bacterial pathogens,distributed in the world widely and caused serious yield losses for economical crops,forestry and orchard.Because phytoplasma cannot be cultured in vitro,it has brought a lot of difficulties to research.Currently,the physiological and biochemical characteristics of the pathogenic mechanism are studied at home and abroad.In this paper,the research progress at home and abroad of endogenous hormones(auxin,mitogen,gibberellin and abscisic acid)of infected plants is to be discussed.
