Special Issue Information
Dear Colleauges,
This Special Issue focuses on the molecular mechanisms that underpin plant stress tolerance, with an emphasis on how plants respond and adapt to a wide range of biotic and abiotic stressors, including drought, waterlogging, salinity, extreme temperatures, heavy metals, and pathogens. Plant stress tolerance involves sophisticated signaling networks mediated by phytohormones such as abscisic acid (ABA), salicylic acid (SA), jasmonic acid (JA), and ethylene, as well as reactive oxygen species (ROS) and secondary messengers like calcium ions and nitric oxide (NO). These signaling cascades orchestrate the regulation of stress-responsive genes through transcription factors (NAC, MYB, and WRKY) and non-coding RNAs (miRNAs and siRNAs). Epigenetic modifications, such as DNA methylation and histone modifications, contribute to stress memory and adaptive responses. Metabolic reprogramming, encompassing osmolyte accumulation, antioxidant activity, and secondary metabolite biosynthesis, plays a critical role in mitigating stress-induced damage. Mechanisms involved in protein homeostasis, including molecular chaperones, ubiquitin-proteasome systems, and autophagy, further support cellular stability under stress conditions. In addition, plant–microbe interactions and microbial bio-stimulants are increasingly recognized for their contributions to stress tolerance by modulating phytohormone levels, nutrient acquisition, and stress-related signaling. This issue invites high-quality research, reviews, and perspectives that leverage advances in omics technologies to elucidate molecular pathways, offering innovative solutions for developing stress-resilient crops to address global climate challenges and ensure agricultural sustainability.

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 100 words) can be sent to the Editorial Office for announcement on this website.
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.
