Special Issue Information

Dear Colleagues,

This Special Issue invites original research, reviews, and short communications that advance the understanding of interactions among plant roots, soils, and microbial communities and their consequences for plant performance and ecosystem function. Submissions may address cultivated and wild plants across scales from molecular processes to landscape dynamics, and should deliver mechanistic insight or robust evidence informing management, conservation, or prediction.

Topics of interest include, but are not limited to, the following:

  • Root traits, exudation, and architecture shaping rhizosphere processes
  • Soil microbial diversity, functional roles, and plant–microbe networks
  • Biogeochemical cycles (nutrient, carbon, water) mediated by root–microbe interactions
  • Plant physiological responses and vigor linked to rhizosphere interactions
  • Responses to abiotic and biotic stress (drought, salinity, pollutants, pests, pathogens) via root–microbe dynamics
  • Effects of land use, vegetation change, restoration, and management practices on root–soil–microbe systems
  • Methods and models: meta‑omics, imaging, isotopes, remote sensing, and simulation approaches for coupled root–soil–microbe processes
  • Translational and applied work: microbiome-informed management, restoration strategies, and indicators of soil and plant health

We welcome interdisciplinary studies spanning ecology, microbiology, soil science, plant physiology, and environmental management. Manuscripts should clearly state the hypotheses, methods, and implications for plant performance or ecosystem function.

Manuscripts should be submitted online at www.mdpi.com by registering and logging in to this website. Once you are registered, click here to go to the submission form. Manuscripts can be submitted until the deadline. All submissions that pass pre-check are peer-reviewed. Accepted papers will be published continuously in the journal (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as short communications are invited. For planned papers, a title and short abstract (about 250 words) can be sent to the Editorial Office for assessment.

Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are thoroughly refereed through a single-anonymized peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. Life is an international peer-reviewed open access monthly journal published by MDPI.

Please visit the Instructions for Authors page before submitting a manuscript. The Article Processing Charge (APC) for publication in this open access journal is 2600 CHF (Swiss Francs). Submitted papers should be well formatted and use good English. Authors may use MDPI's English editing service prior to publication or during author revisions.

Reactive oxygen species (ROS) are critical drivers of redox-associated biogeochemical processes within the rhizosphere, yet the mechanisms of their generation under contaminant stress remain poorly understood. A 24-day pot cultivation experiment with four treatments (control, naphthalene, phenanthrene, and anthracene) was conducted to investigate how polycyclic aromatic hydrocarbons (PAHs) alter the production of three kinds of ROS (e.g., O2•−, H2O2, and OH) in the maize rhizosphere. PAHs promoted the production of rhizosphere ROS, and the promotion effects were compound-dependent, following the order of anthracene > phenanthrene ~ naphthalene. The increases in O2•− content were 55.6%, 14.3%, and 17.9% under anthracene, phenanthrene, and naphthalene treatments. The H2O2 content was enhanced by 58.6% under anthracene treatment, 10.4% under phenanthrene treatment, and 15.4% under naphthalene treatment. The OH concentrations increased by 62.5%, 21.1%, and 0.5% under anthracene, phenanthrene, and naphthalene exposure, respectively. Importantly, the variations in rhizosphere ROS’ content simultaneously fluctuated with stem length, photosynthetic rates, root exudates, dissolved organic carbon (DOC), water-soluble phenols, and enzymes activities induced by PAHs stress. Statistical analysis suggested PAH stress enhanced maize biomass (particularly stem growth), thereby improving photosynthetic efficiency and thus stimulating root exudate release. Root exudates could promote water-soluble phenol and DOC release and enhance microorganism reproduction, thereby mediating abiotic ROS’ production via electron transfer and biotic ROS’ production via extracellular release. These findings clarify the response of rhizosphere ROS to PAHs stress, providing valuable insights for rhizosphere-ROS-mediated remediation of soil pollutants. Full article
