“…[Ca 2+ ] cyt is sensed by proteins that are activated upon Ca 2+ binding such as Ca 2+ -dependent protein kinases (CDPKs), or by proteins that undergo conformational changes such as calcineurin B-like (CBL) proteins to regulate downstream targets. The transcription of several CDPK genes is induced by abiotic stress (6)(7)(8), and Arabidopsis CPK4 and CPK11 loss-of-function mutants show pleiotropic abscisic acid (ABA)-insensitive phenotypes and enhanced salt sensitivity (7). Furthermore, Arabidopsis cpk3 and cpk6 mutants show impaired ABA-and Ca 2+ -induced stomatal closing that is correlated with impaired guard cell ion channel regulation (9).…”

Transient cytosolic Ca 2+ ([Ca 2+ ] cyt ) elevations are early events in plant signaling pathways including those related to abiotic stress. The restoration of [Ca 2+ ] cyt to prestimulus levels involves ATP-driven Ca 2+ pumps, but direct evidence for an essential role of a plant Ca 2+ -ATPase in abiotic stress adaptation is missing. Here, we report on a stress-responsive Ca 2+ -ATPase gene ( PCA1 ) from the moss Physcomitrella patens. Functional analysis of PCA1 in a Ca 2+ transport-deficient yeast mutant suggests that PCA1 encodes a P IIB -type Ca 2+ -ATPase harboring an N-terminal autoinhibitory domain. In vivo localizations identified membranes of small vacuoles as the integration site for a PCA1:GFP fusion protein. PCA1 mRNA levels are up-regulated by dehydration, NaCl, and abscisic acid, and PCA1 loss-of-function mutants (Δ PCA1 ) exhibit an enhanced susceptibility to salt stress. The Δ PCA1 lines show sustained elevated [Ca 2+ ] cyt in response to salt treatment in contrast to WT that shows transient Ca 2+ elevations, indicating a direct role for PCA1 in the restoration of prestimulus [Ca 2+ ] cyt . The altered Ca 2+ response of the Δ PCA1 mutant lines correlates with altered expression levels of stress-induced genes, suggesting disturbance of a stress-associated signaling pathway. We propose that PCA1 is an essential component for abiotic stress adaptation in Physcomitrella involved in the generation of a specific salt-induced Ca 2+ signature.

“…In Oryza sativa , transgenic plants overexpressing OsCDPK7 / OsCPK13 show enhanced resistance to cold, drought, and salt stress 20. OsCDPK13 / OsCPK7 and OsCPK21 are involved in responses to cold and salt stress, respectively 21, 22. In Nicotiana tabacum , two CDPK genes, NtCDPK2 and NtCDPK3 , play an essential role in the defense response, and NtCDPK2 functions together with the stress‐induced MAPKs (mitogen‐activated protein kinases) to control response specificity to abiotic and biotic stresses 23, 24.…”

The calcium‐dependent protein kinase (CDPK) and CDPK‐related kinase gene families in Hevea brasiliensis—comparison with five other plant species in structure, evolution, and expression

Calcium‐dependent protein kinases (CDPKs or CPKs) play important roles in various physiological processes of plants, including growth and development, stress responses and hormone signaling. Although the CDPK gene family has been characterized in several model plants, little is known about this gene family in Hevea brasiliensis (the Para rubber tree). Here, we characterize the entire H. brasiliensis CDPK and CDPK‐related kinase (CRK) gene families comprising 30 CDPK genes (HbCPK1 to 30) and nine CRK genes (HbCRK1 to 9). Structure and phylogeny analyses of these CDPK and CRK genes demonstrate evolutionary conservation in these gene families across H. brasiliensis and other plant species. The expression of HbCPK and HbCRK genes was investigated via Solexa sequencing in a range of experimental conditions (different tissues, phases of leaf development, ethylene treatment, and various abiotic stresses). The results suggest that HbCPK and HbCRK genes are important components in growth, development, and stress responses of H. brasiliensis. Parallel studies on the CDPK and CRK gene families were also extended to five other plant species (Arabidopsis thaliana, Oryza sativa, Populus trichocarpa, Manihot esculenta, and Ricinus communis). The CDPK and CRK genes from different plant species that exhibit similar expression patterns tend to cluster together, suggesting a coevolution of gene structure and expression behavior in higher plants. The results serve as a foundation to further functional studies of these gene families in H. brasiliensis as well as in the whole plant kingdom.

“…At the transcript level, OsCDPK13 responds to various abiotic stresses as well as to hormone levels. OsCDPK13 gene expression and protein accumulation are enhanced in response to cold and GA 3 treatment but suppressed under drought, salt and ABA exposure, and brassinolide treatment [1]. Sense OsCDPK13 transgenic lines are resistant to cold stress; antisense lines show the dwarf phenotype, which suggest that OsCDPK13 has a role in both abiotic stress tolerance and leaf sheath elongation [1].…”

Plants have evolved delicate mechanisms to cope with environmental stress. Following exposure to environmental stimuli, extracellular signals are perceived and transmitted through signal transduction cascades. Upon receipt and transmission of the signals, a number of stressrelated genes are induced, leading to stress adaptation in plant cells. Rice, which is a critical food grain for a large portion of the world's population, is frequently impacted by several abiotic stressors, the most important of which are drought, salinity, and cold. Exposure to environmental conditions outside of acceptable tolerance ranges can negatively affect rice growth and production. In this paper, a review of rice responses to abiotic stress is presented, with particular attention to the genes and pathways related to environmental stress tolerance. It is apparent that, while progress has been made in identifying genes involved in stress adaptation, many questions remain. Understanding the mechanisms of stress response in rice is important for all research designed to develop new rice varieties with improved tolerance.Keywords Abiotic stress . Rice . Signal perception and transduction . Transcription factor . Stress tolerance Plant growth and productivity can be adversely affected by abiotic stress. Plants are exposed to any number of potentially adverse environmental conditions such as water deficit, high salinity, extreme temperature, and submergence. In response, plants have evolved delicate mechanisms, from the molecular to the physiological level, to adapt to stressful environments.Rice is the staple food for more than half of the world's population. Evolved in a semi-aquatic, low-radiation habitat, rice exhibits distinct tolerance and susceptibilities to abiotic stresses among domesticated cereal crops [92]. Rice thrives in waterlogged soil and can tolerate submergence at levels that would kill other crops, and is moderately tolerant of salinity and soil acidity but is highly sensitive to drought and cold [92]. Cultivated over a broad region between 45°north and south latitudes, rice plants are faced with low temperature in temperate regions, submergence in tropical regions, water deficit in humid tropics, and other stressors [109].Arabidopsis is a good model in plant molecular biology and genetics research, and the majority of studies examining the impacts of abiotic stress have employed this plant [37,85,165,183,193]. The signaling pathways and regulatory network in Arabidopsis have been well characterized and well reviewed. Although progresses were also made on rice, reviews were less focused on this most important crop because of little functional genes characterized. Recent years, multiple genes contributing to abiotic stress responses in rice were identified by using genetics, reverse genetics, and molecular biology method. Here, we Rice
