Ca2+ is a universal and ubiquitous secondary messenger that initiates cytosolic signal transduction cascades in cells of organisms from all biological kingdoms responding to myriad extracellular ligands. In plants, cytosolic Ca2+ elevation provides a molecular mechanism that facilitates perception of environmental and internal cues and translation of such perception into altered gene expression and cellular function. Ca2+ signaling cascades require molecular steps that involve the following mechanisms. a) Perception of a signal by a receptor. b) Translation of signal perception into an increase in Ca2+ conduction into the cytosol. c) 'Decoding' of the Ca2+ signal by proteins that can sense transient Ca2+ elevation from homeostatic levels. And d) downstream protein components of the signaling cascade that respond to Ca2+ sensor proteins to facilitate transcriptional reprogramming, altered cell growth and development, and/or increased system fitness. Recent progress in plant Ca2+ signaling has been associated with new insights into all of these aforementioned steps of signaling pathways. In addition, recent work has provided a more intimate linkage of cytosolic Ca2+ signaling and some specific plant physiological processes.
These developments include the identification of specific gene products that are components of Ca2+-conducting ion channel proteins. These Ca2+ transporters include proteins such as annexins, glutamate receptors, and cyclic nucleotide gated channels. Contributions of Ca2+ ATPases and antiporters to 'shaping' Ca2+ signals have also been uncovered. The roles played by Ca2+-binding proteins such as Ca2+-dependent kinases, calmodulins (and calmodulin-like proteins), and calcineurin B-like proteins in numerous signaling cascades have begun to be elucidated. The involvement (in various signaling pathways) of altered Ca2+ levels in plant cell organelles (such as the nucleus) besides the cytosol has been uncovered. Recent work has also led to refinements in our understanding of Ca2+ signal involvement in environmental cues (gravity, circadean rhythms), hormone responses (e.g., auxin), abiotic (e.g., heat shock) and biotic (e.g., pathogen immunity) stress perception, and 'directed' cell growth (e.g., pollen tubes, cell hairs, and formation of Rhizobium sp.-associated root nodules).
This Special Issue hopes to provide a unique compendium that highlights these new developments in our understanding of how this critical messenger molecule contributes to plant function, growth, and response to the environment. Contributions to this special issue are welcomed from scientists working at all system levels, including molecule, cell, organism and environment/ecological perspectives. Studies addressing any of the above aspects of plant cell Ca2+ signaling would be appropriate contributions.

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. Papers will be published continuously (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as 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 refereed through a 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 quarterly 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 550 CHF (Swiss Francs). English correction and/or formatting fees of 250 CHF (Swiss Francs) will be charged in certain cases for those articles accepted for publication that require extensive additional formatting and/or English corrections.
