Special Issue Information
Dear Colleagues,
Plant roots have an amazing ability to develop and flourish in agroecological niches that are shaped by their edaphic environments. However, nutrients and water are not uniformly dispersed within the soil, and the plant’s root system architecture (RSA) becomes ever more important for the optimal use of these scarce resources and displays vast plasticity in response to abiotic stresses. Although cereal crops (maize, rice, and wheat) provide half of the calories consumed by humans, root and tuber crops (RTCs, cassava, sweet potatoes, yams, and potatoes) are the second major source of carbohydrates globally. Without doubt, the status of RTCs is well recognized, and they are of critical importance both in the subtropics and tropics, where cereal production is largely unsuitable. Nevertheless, knowledge of RSA in RTCs under abiotic stress is limited and understudied. We reason that understanding the role of RSA in RTCs under abiotic stress is essential in narrowing the yield gap and improving global food security in low-input, resource-poor agriculture. Thus, assuming the worldwide importance of RTCs, we believe that elevating the importance of RSA will enable a truly inclusive green revolution.
This Special Issue will focus on “Root and Tuber Crop Root System Architecture Adaptations to Abiotic Stress: The Future of Global Food SecurityWe welcome novel research, reviews, and opinion pieces covering all related topics, including root phenotyping, genotyping, “-omics”-related research local adaptation, genetics, gene families, and gene regulation networks, among others. While focused on cassava, sweet potatoes, yam, and potatoes, works on other RTCs under abiotic stress will be considered.

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.
