Special Issue Information

Dear Colleagues,

This Special Issue, "Molecular Mechanisms of Nutrient Stress Responses in Crops: From Physiology to Epigenetics," addresses the critical challenge of ensuring crop productivity under different nutrient conditions. Nutrient stress—both deficiencies and toxicities—severely limits global agricultural yield and sustainability. Thus, understanding the intricate molecular mechanisms that govern plant adaptation to nutrient stress is crucial for developing resilient crop varieties in agriculture. This collection focuses on research spanning from physiological adaptations to cutting-edge epigenetic regulation, offering a holistic view of how crops sense, perceive, transduce, and memorize nutrient stress signals. By bridging traditional physiology with modern molecular, genetic, and epigenetic insights, this Special Issue aims to highlight innovative strategies for precise crop breeding and management, ultimately contributing to food quality and security in the era of rapid climate change and limited soil resources.

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. Agronomy is an international peer-reviewed open access semimonthly 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.

Cadmium (Cd) toxicity threatens global food security and agricultural sustainability. Transcription factors (TFs) act as master regulators of the complex molecular networks involved in Cd detoxification. This review provides a focused synthesis of the molecular mechanisms governing Cd tolerance in plants, encompassing antioxidant defense, Cd chelation and sequestration, Cd uptake and transport, signal transduction, and damage repair pathways. We highlight the pivotal roles of key TFs in these specific processes, such as OsMYB45 in antioxidant defense, OsIRO2 in regulating chelation and storage, OsNAC5 in modulating Cd transport, and OsE2F in facilitating the repair of DNA and protein damage. Furthermore, we evaluate the potential of harnessing these TF-mediated regulatory mechanisms for developing low-Cd rice varieties. By delineating precise correlations between specific TFs and detoxification pathways, this review proposes actionable molecular strategies to mitigate Cd contamination, thereby contributing to ecological and food safety.
