Adverse conditions caused by drought, salt, toxic metals, and extreme temperatures can restrain the growth and development of plants. Environmental abiotic stresses are becoming increasingly frequent and persistent due to global climate change. Plants have evolved complex and sophisticated mechanisms with which to overcome adverse conditions; for example, plant cells initiate signaling transduction in response to abiotic stress, resulting in downstream responses such as specific gene transcription and protein expression. A variety of signaling molecules are involved in the regulation of plant adaptations to diverse environmental stresses, such as abscisic acid, calcium ions, hydrogen sulfide, nitric oxide, hydrogen peroxide, extracellular ATP, ethylene, etc. These signaling molecules mitigate stress-elicited damage at the cellular, tissue, and whole-plant levels. In the majority of cases, stressed plants benefit from signal-mediated water, reactive oxygen species, and ionic homeostasis. More importantly, these signaling molecules form a network in higher plants, with the aim of combatting abiotic stress. In addition to stress-elicited signals, several signaling molecules can also be produced by plant–microbe interactions; for example, the symbiosis of soil fungus with plant roots leads to the production of signals that aid plants in tolerating a stressful environment.
The genetic and transcriptomic bases for physiological acclimation are stress-sensing and signaling networks that activate target genes. Therefore, genetic engineering can be utilized to strengthen signaling networks and improve the stress tolerance of economically important plants. Moreover, other biotechnological approaches, such as mycorrhizations with arbuscular mycorrhizal and ectomycorrhizal fungus, have great potential for improving the water and mineral nutrition of stressed plants.
All types of articles, including original research and reviews, are welcome.

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.
