Special Issue Information
Dear Colleagues,
The study of the mechanisms of light perception and signal transduction in plants has shown the existence of a coordinated signaling network that includes many types of regulation. A wide range of visible light wavelengths is sensed by certain families of photoreceptors: phytochromes for red and far-red light; phototropins and cryptochromes for UV-A and blue light; and UVR8 for UV-B. The effect of light on plants is realized at the level of seed germination, photomorphogenesis, flowering, and many other physiological processes. In addition to photoreceptors, light signaling is due to the functioning of transcription factors (PIF, HYH/HY5, ВВХ, FHY3, FAR1, MYB, CIB1 etc.) and some signaling proteins such as DET1.
Gymnosperms, bryophytes, ferns and lycopsids differ from angiosperms both in the number of photoreceptors and in the features of light signaling, in which various transcription factors play a key role. It is known that gymnosperms have a phytochrome system which is different from those of other plants and also have the ability to synthesize chlorophyll in the dark due to the presence of genes of light-independent protochlorophyllide oxidoreductase. Mosses have one phytochrome and phytochrome interacting factor, and ferns not only have a large number of cryptochrome genes, but also non-light-dependent stomatal movement. All these processes are due to the functioning of light-dependent transcription factors, which can both enhance the light responses of plants and attenuate them. In addition, they demonstrate the interaction with various components of hormonal and ROS signaling systems, which expands their regulatory potential.
This Special Issue will examine the role of transcription factors in the processes of photosynthesis, light signaling, as well as the biosynthesis of pigments and secondary metabolites in angiosperms, gymnosperms, bryophytes, ferns and lycopsid plants.

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. Cells 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.
