Special Issue Information

Dear Colleagues,

Plants are a major source for food, fuel, and fiber and are important contributors to the ecological diversity and sustainability of our planet. As a result of global climate change, episodes of environmental stress are becoming more frequent and are lasting longer, with significant adverse effects on plant growth, development, and crop yield. Although some key components of plant responses to stresses have been identified, our knowledge of the response network is limited. The current Special Issue of IJMS aims to explore the molecular, physiological, and organ response mechanisms of plants under different stress conditions. Moreover, it aims to explore effective ways to improve plant tolerance by gene editing, transgenic, omics, and other technologies. The submission of manuscripts providing insights into the corresponding plant stress response is strongly encouraged, regardless of whether they stem from analyses of classical molecular biology or from omics with a different level.

We invite authors to submit original research and review articles regarding the molecular, physiological and omics aspects of plant stress.

Dr. Li Zhu
Guest Editor

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.

(1) Background: The growth of plants is impacted by salinity and alkali, Lilium pumilum (L. pumilum) is an ornamental plant with strong resistance to salinity and alkali, while the LpPsbP gene is helpful to fully understand the Saline-Alkali tolerance of L. pumilum. (2) Methods: Gene cloning, bioinformatics analysis, expression of fusion protein, determination of physiological indices of plant after Saline-Alkali stress, yeast two-hybrid screening, luciferase complementation assay, chromosome walking to obtain the promoter sequence, and then analyzed by PlantCARE. (3) Results: The LpPsbP gene was cloned and the fusion protein was purified. The transgenic plants had higher Saline-Alkali resistance than the wild type. A total of eighteen proteins interacting with LpPsbP were screened, and nine sites in the promoter sequence were analyzed. (4) Conclusion: Under Saline-Alkali or oxidative stress, L. pumilum will promote the expression of LpPsbP, which will then directly scavenge reactive oxygen species (ROS) in order to protect its photosystem II, reduce its damage, and thus improve the Saline-Alkali resistance of the plant. Moreover, according to some of the literature and the following experiments, two additional speculations are developed on the mechanisms of how two newly found objects, namely jasmonic acid (JA) and FoxO protein, could be involved in ROS scavenging processes were made.
