Atmospheric nitrogen (N)-fixing legume trees are frequently used for the restoration of depleted, degraded, and contaminated soils. However, biological N fixation (BNF) can also be performed by so-called actinorhizal plants. Actinorhizal plants include a high diversity of woody species and therefore can be applied in a broad spectrum of environments. In contrast to N-fixing legumes, the potential of actinorhizal plants for soil restoration remains largely unexplored. In this Opinion, we propose related basic research requirements for the characterization of environmental stress responses that determine the restoration potential of actinorhizal plants for depleted, degraded, and contaminated soils. We identify advantages and unexplored processes of actinorhizal plants and describe a mainly uncharted avenue of future research for this important group of plant species.
固氮豆科树木常用于修复贫瘠、退化和污染的土壤。然而，生物固氮（BNF）也可以由所谓的放线菌根植物来完成。放线菌根植物包括多种木本物种，因此可以应用于广泛的环境中。与固氮豆科植物不同，放线菌根植物在土壤修复方面的潜力在很大程度上仍未得到探索。在本观点中，我们提出了相关的基础研究要求，以描述决定放线菌根植物在贫瘠、退化和污染土壤中修复潜力的环境胁迫反应，确定其相关特征。我们确定了放线菌根植物的优势和未被探索的过程，并描述了这个重要植物物种的未来研究的一个主要未知领域。
