Special Issue Information

Dear Colleagues,

Owing to their sedentary life style, plants endure, grow and propagate exposed to fluctuating conditions in their surrounding environment. They have to adapt to a series of abiotic and biotic factors, and frequently, the adaptation process affects the developmental course of either vegetative or generative growth. The spectral quality or the intensity of light have a dramatic impact on the cell elongation rate and the extent of stem growth, while water and nutrient availability in the soil influences the expansion of the root system via the induction or suppression of lateral root formation. The formation, distribution and positioning of stomata in leaf epidermis are strongly linked to temperature, while both temperature and photoperiod correlate with flowering triggering at the onset of reproduction. In addition, stress conditions, by affecting a number of developmental pathways, define how cells divide and achieve their cell fate specification. Considering such examples of the effect of environmental conditions in plant growth, this Special Issue is dedicated to cellular and molecular mechanisms engaging development to environmental sensing. Since such developmental decisions arise from hierarchical responses in a broad spatiotemporal scale, we invite articles addressing early mechanisms of signal transduction associated with environmentally-controlled developmental programs, comparative transcriptional and epigenetic programs accompanying such differential developmental pathways, whole proteome surveys of protein complements or post-translational modifications and systems approaches modeling developmental responses to abiotic stresses or plant biotic interactions. Additionally, reports on unique environmental adaptation strategies at any level of plant body organization will be of high interest.

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.

Abstract
Stomatal density, spacing, and patterning greatly influence the efficiency of gas exchange, photosynthesis, and water economy. They are regulated by a complex of extracellular and intracellular factors through the signaling pathways. After binding the extracellular epidermal patterning factor 1 (EPF1) and 2 (EPF2) [...] Read more.
Stomatal density, spacing, and patterning greatly influence the efficiency of gas exchange, photosynthesis, and water economy. They are regulated by a complex of extracellular and intracellular factors through the signaling pathways. After binding the extracellular epidermal patterning factor 1 (EPF1) and 2 (EPF2) as ligands, the receptor-ligand complexes activate by phosphorylation through the MAP-kinase cascades, regulating basic helix-loop-helix (bHLH) transcription factors SPEECHLESS (SPCH), MUTE, and FAMA. In this review, we summarize the molecular mechanisms and signal transduction pathways running within the transition of the protodermal cell into a pair of guard cells with a space (aperture) between them, called a stoma, comprising asymmetric and symmetric cell divisions and draw several functional models. The feedback mechanisms involving the bHLH factors SPCH and MUTE are not fully recognized yet. We show the feedback mechanisms driven by SPCH and MUTE in the regulation of EPF2 and the ERECTA family. Intersections of the molecular mechanisms for fate determination of stomatal lineage cells with the role of core cell cycle-related genes and stabilization of SPCH and MUTE are also reported.
