本地植物微生物驱动入侵植物紫茎泽兰微生物群落构建及生长

Abstract

Abstract: The role of local plant microbiome in affecting invasive plant growth remains unclear. We examined how aboveground and belowground microbes from 25 phylogenetically distinct local plants affect the growth and endophytic community assembly of the invasive Ageratina adenophora. Our results showed that both the plant phylogenetics and the microbial community composition of local plants shaped endophytic community assembly in A. adenophora seedlings. Phylogenetic and physicochemical factors of the local plants did not explain their effects on growth of A. adenophora. Instead, growth was affected by both the microbial sources associated with local plants and the endophytes selectively enriched by A. adenophora. Aboveground microbes promoted A. adenophora growth more strongly than belowground soil microbes. On average, A. adenophora seedlings inoculated with aboveground tissues harbored a greater relative abundance of beneficial microbes and a lower relative abundance of detrimental microbes compared to those receiving soil inoculation. These results highlight that the invasive A. adenophora can selectively recruit microbial communities from local plant microbiomes to enhance its growth.

This study reveals that the invasive plant Ageratina adenophora enhances its growth by selectively recruiting beneficial microbes from native plants, particularly above-ground microorganisms, highlighting the role of plant-microbe interactions in biological invasion.

摘要：
本地植物微生物对入侵植物生长的影响仍不清楚。为此，本研究基于25种不同系统发育关系的本地植物，探究其地上和地下微生物对入侵植物紫茎泽兰(Ageratina adenophora)生长和内生菌群落构建的影响。结果发现：1)本地植物系统发育关系和微生物群落组成共同塑造了紫茎泽兰幼苗内生菌群落组成。本地植物系统发育关系和理化因子不能解释其对紫茎泽兰生长的影响，但本地植物相关的微生物以及紫茎泽兰自身富集的内生菌则影响紫茎泽兰幼苗生长。2)与地下土壤微生物相比，地上组织的微生物对紫茎泽兰生长的促进作用更为显著。3)与接种土壤微生物相比，接种地上组织来源微生物的紫茎泽兰幼苗拥有更高丰度的有益微生物和更低丰度的有害微生物。上述结果表明，入侵植物紫茎泽兰能够通过选择性地招募本地植物微生物来促进自身生长。
