Special Issue "Phytohormones on the Metabolism of Bioactive Compounds in Plants under Normal and Stress Conditions"

Dear Colleagues,

Phytohormones (including auxin, abscisic acid, gibberellic acid, brassinosteroids, cytokinins, ethylene, salicylic acid, strigolactones, and jasmonic acids) can trigger physiological effects in plants at a delicate level, and they play a controlling and directing role in the whole process of plant life activities. Phytohormones are also known to regulate plant adaptation to normal and stress conditions by controlling the production of endogenous secondary bioactive compounds, including flavonoids, phenolic acids, alkaloids, saponins, melatonin, and polysaccharides. Additionally, these plant secondary metabolites have demonstrated their role in various health benefits, such as anticardiovascular disease, anticancer, antidiabetic, and other effects. Hence, these compounds in plants have been widely used in the development of plant-based functional foods. Although a massive effort has been devoted to understanding the regulatory networks of phytohormones, the underlying molecular mechanisms of phytohormone-mediated secondary metabolism are still waiting to be deciphered. Therefore, this Special Issue covers aspects of different phytohormones on the metabolism of bioactive compounds in plants under normal and stress conditions. The topics of this Special Issue will include but are not limited to:

• The central roles of phytohormones on secondary metabolism, especially under stress conditions;
• Phytohormones’ crosstalk with each other to regulate the bioactive compounds synthesis in plants;
• Phytohormones coordinating with signaling molecules to maintain sophisticated networks that regulate secondary metabolism;
• Traditional and new techniques for promoting enrichment of bioactive compounds using phytohormones;
• Screening for new chemical compounds with inhibitory or stimulating actions on phytohormones/phytohormonal networks.

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.
