Review: Role of vacuolar cation/proton exchangers (CAX) in biotic and abiotic stress tolerance responses
In their review authors Pittman and Hirschi summarize recent findings on the significance of CAX transporters (Cation/H+ Exchangers) in plant signal transduction and element partitioning. This may open future ways of strategically manipulating the temporal loss of CAX function in agriculturally important crops that may bolster plant immunity, enhance cold tolerance, and fortify resilience against one of agriculture’s most significant challenges, namely flooding. In their review entitled "CAX control: multiple roles of vacuolar cation/H+ exchangers in metal tolerance, mineral nutrition and environmental signalling" the authors also address the use of genetically encoded Ca2+ sensors, the loss of CAX functions and specific stress conditions, as well as the determination of optimal timing and approach for modulating the expression of CAX.
