The Calcium Sensor CBL-CIPK Is Involved in Plant’s Response to Abiotic Stresses

Abstract

Abiotic stress halts the physiological and developmental process of plant. During stress condition, CBL-CIPK complex is identified as a primary element of calcium sensor to perceive environmental signals. Recent studies established that this complex regulates downstream targets like ion channels and transporters in adverse stages conditions. Crosstalks between the CBL-CIPK complex and different abiotic stresses can extend our research area, which can improve and increase the production of genetically modified crops in response to abiotic stresses. How this complex links with environmental signals and creates adjustable circumstances under unfavorable conditions is now one of the burning issues. Diverse studies are already underway to delineate this signalling mechanism underlying different interactions. Therefore, up to date experimental results should be concisely published, thus paving the way for further research. The present review will concisely recapitulate the recent and ongoing research progress of positive ions (Mg2+, Na+, and K+), negative ions (NO3 −, PO4 −), and hormonal signalling, which are evolving from accumulating results of analyses of CBL and CIPK loss- or gain-of-function experiments in different species along with some progress and perspectives of our works. In a word, this review will give one step forward direction for more functional studies in this area.

A laboratory simulation of Arabidopsis seed dormancy cycling provides new insight into its regulation by clock genes and the dormancy‐related genes DOG1, MFT, CIPK23 and PHYA

“…This protein forms a calcium‐sensing complex with CBL1 or CBL9 (CALCINEURIN B‐LIKE PROTEIN), which is involved in iron, nitrate and potassium transport and sensing (Léran et al . ; Manik et al ; Tian et al ). Its role in regulating nitrate transport and signalling by the NITRATE TRANSPORTER 1.1 (NRT1.1) transceptor (duel nutrient transport/signalling function) and the crucial role this plays in the regulation of ABA levels in seeds is well characterized (reviewed in Finch‐Savage and Footitt ).…”

Adaptation of Plants to Salt Stress: Characterization of Na+ and K+ Transporters and Role of CBL Gene Family in Regulating Salt Stress Response

“…It has been found that CBL-CIPK pathways work as regulators in nutrients transport systems, regulating sodium (Na + ) [180], potassium(K + ) [182], magnesium (Mg 2+ ) [183], nitrate (NO 3 − ) [184], and proton (H + ) homeostasis [185]. Recently, in some reviews, particular attention to the possible involvement of the CBLs and CIPKs in different ions sensitivity has been drawn [186,187]. As calcium sensor relieves in plants, calcineurin B-like (CBL) proteins provide an important contribution to decoding Ca 2+ signatures elicited by a variety of abiotic stresses.…”

Signaling with Ions: The Keystone for Apical Cell Growth and Morphogenesis in Pollen Tubes

“…The AtCBL-AtCIPK complex has been heavily implicated in abiotic stress tolerance by adjusting the levels of K + through AtAKT1 (Manik et al, 2015). Of the 26 different CIPKs identified within the Arabidopsis genome, AtCIPK10, AtCIPK11, AtCIPK12, AtCIPK14, and AtCIPK19 are strongly expressed in PTs (Konrad et al, 2011;Zhou et al, 2015a).…”
