Special Issue Information
Dear Colleagues,
Nutrients as macronutrients (e.g., N, P, and K) and micronutrients (e.g., Fe, Zn, Mn, and B) are essential to plant growth, plant reproduction, and interactions of plants with the environment. Plants have different needs for nutrients during their life phases depending on their local environment and they adjust their uptake of nutrients accordingly. Plants actively acquire many nutrients in sufficient amounts, and they strictly control these processes so that nutrients do not become overly reactive and toxic to the plant itself. Furthermore, plants control the transport, storage, and allocation of nutrients to the different plant parts. Many studies in the area of plant nutrition have uncovered the surprisingly highly diverse array of cellular mechanisms that control nutrient uptake. These can range from transcriptional control by DNA-binding, trans-acting transcription factor complexes and cis-regulatory codes to post-transcriptional and post-translational control mechanisms involving RNA biology, protein–protein interactions, protein–RNA interactions, ubiquitination, protein stability, post-translational modifications, intracellular transport regulation, and short- and long-distance transport regulation. To date, we have uncovered initial nutrient sensing steps and receptors in only a few cases. An amazing finding is that nutrient transport can be coupled with nutrient perception in the form of so-called transceptors. Identifying the processes that control nutrient uptake is crucial to breeding crops that better tolerate adverse soil conditions and help to limit fertilizer use. Biofortification—the regulation of nutrient acquisition and allocation to edible plant parts—is a promising approach to enhancing nutritional properties. Therefore, for this Special Issue, we welcome the submission of articles (original research, perspectives, hypotheses, opinions, reviews, modeling approaches, and methods) that focus on nutritional cell biology or regulatory aspects of nutrient uptake at any level (transcriptional, post-transcriptional, post-translational, cell biological mechanism, signaling, short distance, or long-distance) in model plants, crop plants, or ecologically interesting plants.

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. Agronomy 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.
