Special Issue Information
Dear Colleagues,
Salinity is one of the major abiotic stresses that retard the growth and productivity of crops, particularly in hot and dry areas of the world. It is an intensive topic on which many studies have been conducted, with the aim of understanding the physiological and molecular responses involved in plant salinity stress. In recent years, with the rapid progress of molecular technologies, scientists have acquired more powerful tools to reveal in-depth mechanisms and to establish crop breeding programs for plant salinity tolerance. Hence, this Special Issue aims to unravel the whole picture of plant salinity tolerance by expanding knowledge that focuses on the molecular aspects of the following subtopics.
1. Mechanistic insights: Explore mechanisms associated with responses to salinity stress using modern molecular tools such as high-throughput technologies
- Crucial cell signaling networks and integrative multi-omics;
- Structure and function of key signaling components involved in membrane Na+, K+, Ca2+, and Cl− transport systems, as well as the role of secondary messengers;
- Role of phytohormones (e.g., the involvement of abscisic acid);
- Role of biostimulants such as melatonin.
2. Biotechnology: Enhancing the salinity tolerance of plants using biotechnological tools
- The identification of candidate genes for salinity tolerance;
- Genetic engineering for salinity tolerance by altering the patterns of gene expression, including technologies involving targeted genome editing;
- In vitro screening and induced mutation, including polyploidy, to obtain salinity-tolerant genotypes.
3. Breeding: Developing salinity-tolerant crops that have improved growth, yield, and product quality in salt-affected fields.
- Explore genetic resources for salinity tolerance in crops based on molecular-marker-assisted methods such as the use of QTLs and SNPs for genetic mapping;
- Plant breeding programs for developing salinity-tolerant crops.
4. Agricultural practices: The use of agricultural techniques and/or chemical or biological regimes to improve plant growth and productivity when subjected to soil salinity
- The application of beneficial soil microorganisms such as mycorrhizal fungi and growth-promoting bacteria;
- The utilization of plant growth regulators, osmoprotectants, antioxidants, and trace elements;
- Studies on the effects of organic and inorganic immobilizing amendments on salinity stress alleviation.
We invite scientists to contribute both original research articles and reviews for this Special Issue. Please note that approaches will only be considered for peer-review if they are extended to provide further in-depth insights into the mechanisms associated with responses to salinity stress.

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. International Journal of Molecular Sciences is an international peer-reviewed open access semimonthly journal published by MDPI.
Please visit the Instructions for Authors page before submitting a manuscript. There is an Article Processing Charge (APC) for publication in this open access journal. For details about the APC please see here. 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.
