Abstract

Grazing exclusion and land abandonment are commonly adopted to restore degraded ecosystems in semiarid and arid regions worldwide. However, the temporal variation in the soil- versus root-associated microbiome over plant species turnover during secondary succession has rarely been quantified. Using the chronosequence restored from fenced grassland and abandoned farmlands on the Loess Plateau of China, we characterized the dynamics of the soil- and root-associated microbiome of host plant with different dominance statuses during secondary succession from 0 to 40 years. Our results revealed that the root microhabitat, the host plant and their interactions were the main contributors to the bacterial community shift (R2 = 15.5%, 8.1%, and 22.3%, respectively), and plant interspecies replacement had a greater effect on the shift in the root-associated microbial community than intraspecies replacement did during succession. The root-associated bacterial community of pioneer plants was particularly responsive to succession, especially the endosphere community. Endosphere microbial diversity was positively correlated with host plant coverage change, and the diversity and abundance of taxon recruitment into the endosphere of pioneer plants from the surrounding environment decreased as succession progressed. The community assembly processes also indicated that the endosphere microbiota are strongly selected in younger host plants, whereas stochastic processes dominate in aged host plants. Our study provides evidence of the unique response of the root-associated microbiome to the replacement of plant species during secondary succession, and the function of endosphere microbes should be considered when studying plant-microbe feedback.

土壤-根连续统微生物群落动态与次生演替过程中植物物种更替有关。
在世界范围内的半干旱和干旱区,禁止放牧和放弃土地是恢复退化生态系统的常用方法。然而,在次生演替过程中,土壤与根相关微生物组在植物物种更替过程中的时间变化很少被量化。利用黄土高原封育草地和撂荒农田恢复的时间序列,研究了不同优势状态寄主植物在0 ~ 40年次生演替过程中土壤和根系相关微生物群的动态变化。结果表明,根微生境、寄主植物及其相互作用是影响植物群落迁移的主要因素(R2分别为15.5%、8.1%和22.3%),植物种间更替对根相关微生物群落迁移的影响大于种内更替。先锋植物的根相关细菌群落对演替反应特别强烈,尤其是内球菌群。内圈微生物多样性与寄主植物盖度变化呈正相关,随着演替的进行,先锋植物从周围环境中招募到内圈的分类群的多样性和丰度逐渐降低。群落组装过程还表明,内球微生物群在年轻寄主植物中被强烈选择,而在年老寄主植物中随机过程占主导地位。我们的研究提供了根相关微生物组在次生演替过程中对植物物种替代的独特响应的证据,并且在研究植物-微生物反馈时应考虑内球微生物的功能。
