Special Issue Information
Dear Colleagues,
Phytohormones are major growth regulators, contributing to every aspect of a plant’s life. Plants produce a delicate level of hormones to support their growth and metabolism under normal conditions. Plants are also intermittently exposed to environmental stresses, both biotic and abiotic, which are major constraints to sustainable agriculture. To survive in stress situations, plants have to elicit appropriate adaptive responses, most of which are governed and directed by a number of plant hormones, including abscisic acid, auxin, brassinosteroids, cytokinins, ethylene, gibberellins, jasmonic acids, salicylic acid, and strigolactones. Phytohormones are also known to regulate plant adaptation/acclimatization to environmental stresses by controlling the production of various stress proteins, osmoprotectants, antioxidants, and ion transporters. Plants carry out most of these strategies by modulating the cellular levels of multiple phytohormones, which then relay the signals into morphological, biochemical, and physiological adaptations, including changes in root and shoot biomass, water transport, stomatal movement, leaf senescence, antioxidant defenses, mineral homeostasis, and rate of grain filling. Moreover, phytohormones coordinate with various signaling molecules, such as hydrogen peroxide, nitric oxide, and hydrogen sulphide, to maintain sophisticated networks that finally determine the output of hormonal actions. Although a massive effort has been devoted to understanding the regulatory networks of phytohormones, the underlying mechanisms of phytohormone-mediated plant adaptation/acclimatization to various stresses are still waiting to be deciphered. For this Special Issue, we invite potential authors to submit their latest interesting findings on the roles of phytohormones and their crosstalk in various aspects of plant growth and development, as well as stress adaptation/acclimatization. The topics of this Special Issue will include, but are not limited to:
- the central roles of phytohormones in plant growth and development, especially under environmental stress conditions;
- how plant hormones interact with each other and also with other signaling molecules to orchestrate signal transduction;
- how environmental stresses modify the metabolism of hormones and the hormonal balance in plants;
- how interactions between phytohormones and environmental stresses regulate the induction or repression of stress-responsive genes; and
- screening for new chemical compounds with inhibitory or stimulating actions on phytohormones/phytohormonal networks.
We welcome research and review articles that will augment our understanding of this fascinating field of phytohormonal research in order to facilitate the development of plants with greater fitness under the ever-changing environmental conditions.

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.
