) signals are essential transducers and regulators in many adaptive and developmental processes in plants.
Protective responses of plants to a variety of environmental stress factors are mediated by transient changes of Ca
tion in plant cells. Ca
ions are quickly transported by channel proteins present on the plasma membrane. During responses
to external stimuli, various signal molecules are transported directly from extracellular to intracellular compartments via
channel proteins. Three types of Ca
channels have been identiﬁed in plant cell membranes: voltage-dependent
-permeable channels (VDCCs), which is sorted to depolarization-activated Ca
-permeable channels (DACCs) and
-permeable channels (HACCs), voltage-independent Ca
-permeable channels (VICCs).
They make functions in the abiotic stress such as TPCs, CNGCs, MS channels, annexins which distribute in the organelles,
plasma membrane, mitochondria, cytosol, intracelluar membrane. This review summarizes recent advances in our knowledge
of many types of Ca
channels and Ca
signals involved in abiotic stress resistance and responses in plant cells.

Plants are subject to numerous abiotic stress factors (includ-
ing drought, salinity, high or low temperature, and hypo-
osmotic conditions) that suppress growth and may even
cause death. Accordingly, plants have evolved a variety of
physiological mechanisms (collectively termed “environ-
mental adaptability”) to resist abiotic stress factors (Gilroy
and Trewavas 2001).
) functions as a second messenger in
many biotic activities. Signals are transmitted through Ca
conducting channels, and are able to sense and respond to
internal and environmental stimuli (Jammes et al. 2011).
In plants, these are essential mechanisms, and Ca

is signiﬁcant in signal transduction for
gene expression and cell cycle control (Berridge et al. 2003),
and is involved a variety of plant biological processes such
as light signaling (Harada et al. 2003), hormone responses
(Munemasa et al. 2007), cell growth (Frietsch et al. 2007),
stress and plant-pathogen interactions (Qi et al. 2010).
Two general categories of transfer systems for Ca
port are found in plants: inﬂux and eﬄux via channels and
channels are a type of transmembrane chan-
nel protein present on the surface of plant cells or organs
that transmit Ca
quickly and speciﬁcally. Ca
are thus essential in transfer and regulation of Ca
is involved in all responses to abiotic stress. This review
describes recent research advances on Ca
their roles in abiotic stress response mechanisms.
Generation of Ca
Plants have strong adaptive abilities to sense changes in their
surrounding environment and to regulate their growth and
development through appropriate responses to stimuli. To
induce expression of related genes, stress signals originating
outside the cell must cross the cell wall and reach the cell
