Special Issue Information
Dear Colleagues,
Hydrogen sulfide (H2S) was considered a toxic gas at the time of its discovery. Now, it has come to be considered as the third most important gaseous signaling molecule that has been extensively studied. As a novel small signaling molecule, H2S can easily enter cells and penetrate the intercellular space. It is both an endogenous sulfide and a key node of sulfur metabolism in biological organisms. Reactive oxygen species (ROS) are toxic by-products of aerobic metabolism, but which also act as plant signaling molecules in various processes, such as plant growth and development, and biotic and abiotic stress responses. When ROS accumulate excessively in plants, intracellular homeostasis is disrupted, seriously affecting plant growth and development. H2S might play a key role in regulating intracellular ROS homeostasis in plants, which is considered to be an effective defense agent against various stresses. H2S and ROS have also been suggested to be involved in various physiological and biochemical processes through different signal transduction pathways, as well as different molecular forms.
This Special Issue focuses on recent studies that aim to determine the role and mechanisms of H2S and ROS in plants. However, there are many other molecular mechanisms of crosstalk, which are involved in the regulation of various physiological and biochemical processes by H2S and ROS. For example, other gas signaling molecules, hormones and persulfidation modifications have important implications for the role of H2S and ROS in plants. Studies providing such information are welcome, as they will help to elucidate the important role of H2S and ROS in plants.

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.
