摘要

虽然近年来海洋微生物群得到了越来越多的关注,但与陆地系统相比,它们的研究仍然不足。随着分子方法的不断完善,微生物组研究已扩展到其他重要的海洋生物,如大型藻类。微生物组在大藻的健康、对环境条件的适应和对气候压力的恢复能力中起着关键作用。影响藻类微生物组的主要因素有宿主特异性(遗传、功能特征、门和种特性)、生命阶段、形态、菌体区域和组织年龄。微生物群落结构的其他重要驱动因素包括时空分布和环境条件,特别是随着气候变化全球压力因素的加剧。入侵海藻的微生物群可能增强其对本地物种的竞争力的机制尚不清楚。然而,有证据表明,与气候适应能力一样,入侵潜力与相关微生物群的功能灵活性有关,从而使宿主能够适应新的环境条件。本综述的主要目的是综合目前对大藻微生物组的认识,并在发现不足的基础上提出微生物组研究的未来方向。基于检测到的知识空白,迫切需要在未来气候变化情景下通过化学信号将宿主和微生物组基因表达联系起来的多因素实验研究,标准化分析方法,并关注代表性不足的地理区域和物种。虽然藻类微生物组研究在预测和减轻气候变化和入侵物种的影响方面具有很大的前景,但采用新的工具和解决生态相关的机制和应用问题对于推进这一领域至关重要。

Advancements in Algal Microbiome Research: A Game-Changer for Climate Resilience and Invasion Success?

While marine microbiomes have been getting more attention in recent years, they remain understudied compared to those of terrestrial systems. With the refinement of molecular methods, microbiome research has extended to other key marine organisms such as macroalgae. The microbiome plays a key role in macroalgal health, adaptation to environmental conditions, and resilience to climate stressors. The main factors affecting the algal microbiome are host specificity (genetics, functional profile, phylum and species identity), life stage, morphology, thallus region, and tissue age. Other significant drivers of microbiome community structure include spatiotemporal distribution and environmental conditions, especially as global stressors intensify with climate change. The mechanisms through which the microbiome of invasive seaweeds might enhance their competitiveness over native species are still unclear. However, there is evidence that, like climate resilience, invasive potential is linked to the functional flexibility of associated microbiota, allowing the host to adapt to the new environmental conditions. The main objective of this review was to synthesize the current understanding of the macroalgal microbiome and propose future directions in microbiome research based on identified shortcomings. Based on the knowledge gaps detected, there is an urgent need for multi-factorial experimental studies that link host and microbiome gene expression through chemical signals under future climate change scenarios, standardization of analytical methods, and a focus on underrepresented geographical regions and species. While algal microbiome research holds great promise for predicting and mitigating the effects of climate change and invasive species, embracing new tools and tackling ecologically relevant mechanistic and applied questions will be essential to advancing this field.

期刊介绍: The journal Microbial Ecology was founded more than 50 years ago by Dr. Ralph Mitchell, Gordon McKay Professor of Applied Biology at Harvard University in Cambridge, MA. The journal has evolved to become a premier location for the presentation of manuscripts that represent advances in the field of microbial ecology. The journal has become a dedicated international forum for the presentation of high-quality scientific investigations of how microorganisms interact with their environment, with each other and with their hosts. Microbial Ecology offers articles of original research in full paper and note formats, as well as brief reviews and topical position papers.
