Biochar as a Soil Amendment: Unraveling Molecular Mechanisms Underpinning Plant Growth Promotion via Gene Expression and Regulatory Networks

Dear Colleagues,

Biochar has gained recognition as a sustainable soil amendment with the potential to enhance plant productivity and soil quality. Beyond its known effects on soil physicochemical properties and microbial dynamics, recent studies have revealed that biochar can influence plant growth at the molecular level. This Special Issue invites contributions that investigate how biochar alters gene expression profiles, hormone signaling pathways, and regulatory networks in plants. Of particular interest are studies exploring biochar’s role in modulating transcription factors, stress-responsive genes, nutrient transporter activity, and phytohormone biosynthesis. Omics-based approaches such as transcriptomics, proteomics, and metabolomics are encouraged to provide mechanistic insights. The Issue also welcomes interdisciplinary research that connects soil chemistry, biochar characteristics, and rhizosphere interactions with downstream molecular responses in plants. Together, these contributions will help clarify how biochar mediates plant growth and stress resilience through molecular and genetic regulation.

Manuscript Submission Information

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-blind peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. Current Issues in Molecular Biology 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 2200 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.
