根际微生物与植物再植病的发生发展关系

Association of rhizosphere soil microbiome with the occurrence and development of replant disease-A review

摘要:

植物再植病严重危害农作物的生长发育，形成原因复杂，最新的研究显示它与根际微生态的变化相关，其中主要涉及根际微生物菌群结构的变化。现代高通量测序技术的迅速推广使得根际微生物和再植病间关系成为新的研究热点；本文根据国内外植物再植病病因、根际土壤微生物多样性以及它们与植物生长发育关系等多方面的研究成果，综合分析植物再植病与根际微生物间的关系，以期从根际微生物种群动态变化的角度认识植物再植病的病因并为防治提供新的思路。

Abstract:

Replant disease devastates crop growth, and its disease etiology has not been fully elucidated. The latest research revealed its close association with the changes of rhizosphere microecology, especially the changes in rhizosphere microbial community structure. With the advance of modern high-throughput DNA sequencing technology, the relationship between rhizosphere microbiome and replant diseases has become a popular research focus. This review comprehensively analyzes the currently available literatures regarding to the relationship between rhizosphere microbiome, crop growth and replant diseases. In summary, a new perspective for the disease etiology and possible prevention regimen has been arisen from better understanding the association between replant disease and the dynamic changes of rhizosphere soil microbial population.
