Tolerance Mechanisms of Plants Against Abiotic Stresses

Dear Colleagues,

Plants are constantly exposed to various abiotic stresses, which can include drought, salinity, extreme temperatures, flooding, and heavy metal toxicity. These stresses can severely limit plant growth, development, and yield. To cope with these challenges, plants have evolved various tolerance mechanisms at morphological, physiological, biochemical, and molecular levels, including the following:

• Root system development;
• Leaf morphology changes;
• Osmoregulation;
• Photosynthetic adjustments;
• Hormonal regulation;
• Antioxidant defense systems;
• Gene expression changes;
• Signaling pathways;
• Epigenetic changes.

The tolerance mechanisms of plants against abiotic stresses are complex and multifaceted. Understanding these mechanisms is crucial for improving crop resilience and developing strategies for sustainable agriculture in the face of climate change and environmental challenges. Future research is essential to unravel these processes and enhance the ability of plants to cope with abiotic stresses.

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 250 words) can be sent to the Editorial Office for assessment.

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.
