Abstract

Bioremediation of degraded soils is increasingly necessary due to rising food demand, reductions in agricultural productivity, and limitations in total available arable area. Several bioremediation strategies could be utilized to combat soil degradation, with phytoremediation emerging as a standout option due to its in situ approach and low implementation and maintenance costs compared to other methods. Phytoremediation is also a sustainable solution, which is increasingly desirable to blunt the progression of global warming. Actinorhizal plants display several desirable traits for application in phytoremediation, including the ability to revegetate saline soil and sequester heavy metals with low foliar translocation. Additionally, when grown in association with Frankiaceae endophytes, these abilities are improved and expanded to include the degradation of anthropogenic pollutants and the restoration of soil fertility. However, despite this significant potential to remediate marginalized land, the actinorhizal-Frankiaceae symbiosis remains heavily understudied and underutilized. This review aims to collate the scattered studies that demonstrate these bioremediation abilities and explain the mechanics behind such abilities to provide the necessary insight. Finally, this review will conclude with proposed future directions for utilizing this symbiosis and how it can be optimized further to facilitate improved bioremediation outcomes.

放线菌植物和弗兰科植物:被忽视的植物修复未来。
由于粮食需求不断增加、农业生产率下降以及可耕地总面积有限,对退化土壤进行生物修复变得越来越有必要。有几种生物修复策略可用于防治土壤退化,其中植物修复法因其原位方法以及与其他方法相比较低的实施和维护成本而成为一种突出的选择。植物修复也是一种可持续的解决方案,这对于减缓全球变暖的进程越来越重要。放线菌植物在植物修复中的应用显示出几种理想的特性,包括重新植被盐碱土壤和固存重金属的能力,而且叶片转移率低。此外,当植物与法兰西内生菌共同生长时,这些能力会得到改善和扩展,包括降解人为污染物和恢复土壤肥力。然而,尽管放线菌-弗兰科植物共生具有修复边缘化土地的巨大潜力,但对其的研究和利用仍然严重不足。本综述旨在整理证明这些生物修复能力的零散研究,并解释这些能力背后的机理,以提供必要的启示。最后,本综述将提出利用这种共生关系的未来方向,以及如何进一步优化这种共生关系,以促进改善生物修复效果。

期刊介绍: The journal is identical in scope to Environmental Microbiology, shares the same editorial team and submission site, and will apply the same high level acceptance criteria. The two journals will be mutually supportive and evolve side-by-side. Environmental Microbiology Reports provides a high profile vehicle for publication of the most innovative, original and rigorous research in the field. The scope of the Journal encompasses the diversity of current research on microbial processes in the environment, microbial communities, interactions and evolution and includes, but is not limited to, the following: the structure, activities and communal behaviour of microbial communities microbial community genetics and evolutionary processes microbial symbioses, microbial interactions and interactions with plants, animals and abiotic factors microbes in the tree of life, microbial diversification and evolution population biology and clonal structure microbial metabolic and structural diversity microbial physiology, growth and survival microbes and surfaces, adhesion and biofouling responses to environmental signals and stress factors modelling and theory development pollution microbiology extremophiles and life in extreme and unusual little-explored habitats element cycles and biogeochemical processes, primary and secondary production microbes in a changing world, microbially-influenced global changes evolution and diversity of archaeal and bacterial viruses new technological developments in microbial ecology and evolution, in particular for the study of activities of microbial communities, non-culturable microorganisms and emerging pathogens.
