青枯菌种内分型研究进展

Advance of the Classification in Ralstonia solanacearum Species

青枯菌是一种土传性的细菌性病原菌,可侵染50多个科的200多种植物,包括马铃薯、烟草和番茄等茄科经济作物,严重危害一些农作物的产量和质量。青枯菌是一个复杂的种,综述青枯菌种内分型的研究进展,包括生理小种(races)、生化型(biovars)、种系型(phylotypes),并对不同的分型进行比较,期望为烟草青枯菌系的构成和遗传多样性分析,以及为研究烟草与青枯菌互作提供其分析信息。

Ralstonia solanacearum is a soilborne Gram-negative bacterial pathogens, infecting more than 200 species belonging to more than 50 botanical families, including Solanaceae economic crops such as potatoes, tobacco and tomato, cause to serious loss of their yield and quality. R. solanacearum is a complex species, this paper reviewed the research progress of classification in the R. solanacearum, including the races, biovars and phylotypes, and the different type schemes were compared, which povide phylotype information for the analysis of the composition and genetic diversity of the tobacco R. solanacearum, for the study the interaction between tobacco and R. solanacearum.
