The Physiology of Abiotic Stress in Plants

Dear Colleagues,

Global change involves an undeniable reduction in the resources available to plants, and therefore the accentuation of abiotic stresses. Simultaneously, the increase in population determines the need to ensure greater quantities of food and other plant products that are useful to the growing population. The need to identify cropping systems with lower inputs increases the intensity of the abiotic stresses that plants must face. The use of innovative technical means, such as biostimulants, could be a solution, but often only the possible positive results of their use are analyzed, without delving into what the mechanisms of action may be. A powerful means by which to understand the response of plants and, therefore, to try to reduce the impact of abiotic stresses is the analysis of plant physiology. These are often non-destructive investigations that have the merit of providing precise indications of the mechanisms of action. The purpose of this Special Issue is to analyze the physiology of abiotic stresses in plants to define the response mechanisms of action and which strategies plants can implement to overcome suboptimal conditions that increasingly reduce them more frequently and with greater intensity.

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. Plants 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 2700 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.
