Special Issue Information

Drought limits water uptake by plant roots and results in reduced transpiration and photosynthesis, which can have drastic effects on growth and productivity of food and bioenergy crops. Plant responses to water stress involve complex cross-talk between different regulatory pathways, including physiological and molecular adjustments at whole-plant, organ, tissue, and cellular levels. The root system is the primary plant organ that senses water deficiency in a drying soil and generates the first signals that orchestrate the machinery leading to water stress responses. Recently, an expanding area of interest has been devoted to characterizing root traits associated with water stress. However, our knowledge of root responses to drought in its molecular, physiological, and morphological levels remains fragmentary. Research in this area will lead to identifying root traits or “ideotypes” that have the potential to improve plant productivity under water stress.

This Special Issue will focus, as titled, on “Root Traits for Crop Improvement under Water Stress.” We seek articles describing the molecular physiology and phenomics of root system architecture in response to water-deficit condition. We welcome original research articles and reviews covering all related topics including root metabolite and exudate profiling, ion uptakes, hydraulic conductivity, xylem diameter, genotype–phenotype association, and non-invasive imaged-based phenotyping.

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 papers will be 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 1600 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.
