Special Issue Information
Dear Colleagues,
Phenolic compounds are complex and diverse plant secondary metabolites which play important special roles in plant growth and development and adaption to the environment and resistance to abiotic stress. At the same time, phenolics have attracted extensive attention because of their antioxidant and anticancer effects on the human body. Therefore, scientific and technological workers have gradually carried out a lot of research on the structure, composition, properties, and functions of plant phenolics and used stress methods to treat germinating seeds or seedlings to synthesize more phenolics. Gamma-aminobutyric acid (GABA) is a 4-carbon non protein amino acid. It has been widely studied as an inhibitory neurotransmitter in mammals, and it also has the functions of lowering blood pressure and sedation in the human body. In plants, abiotic stress can enhance GABA synthesis. With the deepening of research, GABA as a signal molecule involved in the synthesis of plant secondary metabolites has been gradually confirmed. However, the receptor of GABA in plants has not been clarified. Not much is known about how GABA binding and interactions with proteins occur, how stress is translated into a signal that results in phenolics accumulation and changes physiological and biochemical metabolism, and whether the generated signal is transient or sustained, as well as the molecular basis of GABA regulation of transporters and acceptors that promote the growth of sprouts or seedlings under stress. Hence, this Special Issue will focus on the regulation, signal transduction, and mechanism of GABA in plant phenolic accumulation under abiotic stress.

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.
