Mechanism of Drought and Salinity Tolerance in Crops

Dear Colleagues,

Drought and salinity are the two major abiotic stresses constraining crop growth and productivity globally. While due to climate change, these stresses are gradually becoming more severe in many places, mainly in arid or semi-arid areas, which covers nearly half of the Earth’s land surface. Meanwhile, drought is frequently associated with salinity stress in coastal, arid, and semiarid regions. When the soil water evaporates, the salts become concentrated in the soil solution, resulting in combined drought and salinity. Exploring and investigating the mechanisms of how drought, salinity and their combination affect crop growth and development, as well as understanding the crop drought and salinity stress tolerance will help to improve agricultural crop production and maintain the food security. Although a plenty of researches have been performed to investigate plant drought and salinity stress responses, there is still a big gap for us to prevent or reduce the adverse effects from drought and salinity both effectively and efficiently, especially in our practical crop production. This Special Issue of Plants will focus on understanding of how crops response and tolerance to drought and salinity, including physiological, biochemical and molecular mechanisms.

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.
