Special Issue Information
Dear Colleagues,
Ecological and management factors that negatively impact plant growth, development, and survival are known as stress factors. Plants can sense changes in their environment and respond or acclimate to stress through integrated events at all levels of organization, including their anatomy, morphology, physiology, biochemistry, and gene expression. Various Plant Growth Regulators (PGRs), such as abscisic acid, jasmonic acid, nitric oxide, and ethylene, mediate plant sensing and acclimation mechanisms, providing both general and specific responses to stress conditions. Many plant species exhibit high phenotypic plasticity, meaning they can express a wide range of phenotypes, allowing them to cope with changing environmental conditions, and be distributed or cultivated across a broader range of locations. However, the expansion of cultivation sites and the effects of global warming can create extreme biotic and abiotic conditions, potentially overwhelming plant defense mechanisms and resulting in oxidative damages. For example, biotic stress includes insect pests, fungal diseases, bacterial pathogens, viruses, and weed competition, while abiotic stress encompasses drought, salinity, extreme temperatures, UV radiation, and strong winds. Acclimation responses involve changes in the vegetative/reproductive ratio and the accumulation of primary/secondary metabolites within plant tissues, which subsequently influence the chemical and sensory attributes of harvested products. This Special Issue aims to gather original research papers focusing on the signaling and regulation of PGR-mediated acclimation mechanisms in various plants species under a range of stressful biotic and abiotic factors. Additionally, it seeks to include papers that evaluate PGRs as management tools to control vegetative growth, fruit yield, and the profiles of primary and secondary metabolites, thereby influencing the nutritional attributes of consumable parts.

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. Plants is an international peer-reviewed open access semimonthly journal published by MDPI.
Please visit the Instructions for Authors page before submitting a manuscript. The Article Processing Charge (APC) for publication in this open access journal is 2700 CHF (Swiss Francs). 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.
