摘要:

所有栖息在植物宿主上的微生物被称为植物微生物组。随着高通量测序的发展,植物微生物组作为一个复杂的生态系统已经被广泛关注。植物微生物组群落的结构和功能等方面已得到了深入细致的研究,而植物与微生物组的互作机制仍有待探索。全基因组关联分析(Genome-Wide Association Analysis Study, GWAS)作为一种有效的手段已经被用来研究宿主和微生物组之间的关系。本文基于国内外最新研究进展,从以下方面进行综述,包括植物对微生物组的调控,以及如何应用GWAS研究植物与微生物组互作遗传机制,重点阐述了植物与微生物组关联分析中微生物组作为“拓展表型”数据的选择,并且总结了植物宿主影响微生物组的遗传机制,旨在阐明宿主遗传因素对微生物组的调控,增进对植物与微生物组互作的理解。

Abstract:

All the microorganisms that inhabit the plant host are called the plant microbiome. With the development of high-throughput sequencing, the plant microbiome as a complex ecosystem has been widely concerned. Despite increasing recognition of the structure and function of plant microbiome the interaction mechanism of plants and microbiomes remains largely elusive. As an effective method, the recent application of genome-wide association analysis study(GWAS)is instrumental in unravelling this issue.This review focuses on the latest research progresses by the following two aspects: the effect of plant on microbiome, and the genetic mechanism of plant-microbiome interaction. The selection of phenotypic data in plant-microbiome association analysis is elaborated, and genetic mechanisms by different hosts are summarized, aiming to elucidate the host regulation of the microbiome and enhance the understanding of plant-microbiome interactions.
