About this Research Topic
Photoautotrophs play a significant role in the critical zone (CZ); the continuum between unweathered rock to the top of vegetation. They fuel processes at the mineral interface mediated by microorganisms, exploit nutrients over mycorrhiza and roots from soil in complex feed-back loops and react to the steadily changing conditions to capture energy that is crucial for all life in the involved compartments.
The research fields along the critical zone are largely fractioned, although both the meaning of the word as well as the concept requires a holistic, hence biogeochemical approach.
With this Research Topic, we aim at promoting studies that unite plant science, bioscience, and geoscience at least over the multitrophic interactions in the CZ.
We welcome manuscripts considering two or more processes at the interfaces and feed-back loops across the listed scales:
• Stress reactions of biota along the CZ in response to global change
• Plant- atmosphere interchange & bioaerosols
• Plant nutrition and ecosystem stability
• Mycorrhizosphere- soil interactions
• Organic substance- mineral interaction
• Mineral- microorganism interactions, and biogenic weathering
Please note:Studies falling into the categories below will not be considered for review, unless they are expanded and provide functional or mechanistic insights into the biological system or process being studied:
i) Descriptive collection of transcripts, proteins, or metabolites, including comparative sets as a result of different conditions or treatments;
ii) Descriptive studies that define gene families using basic phylogenetics and the assignment of cursory functional attributions (e.g. expression profiles, hormone or metabolites levels, promoter analysis, informatic parameters).
Keywords: Critical Zone, biogeochemical processes, ecosystems resilience, global change-induced stresses, tipping points, symbiosis, scales dilemma
Important Note: All contributions to this Research Topic must be within the scope of the section and journal to which they are submitted, as defined in their mission statements. Frontiers reserves the right to guide an out-of-scope manuscript to a more suitable section or journal at any stage of peer review.
