TL;DR: A direct interconnection between CBL-CIPK-mediated Ca(2+) signaling and ROS signaling in plants is identified and evidence for a synergistic activation of the NADPH oxidase RBOHF is provided by directCa(2+)-binding to its EF-hands and Ca( 2+)-induced phosphorylation by CBL1/9-C IPK26 complexes.

TL;DR: RBOHF is identified as a convergence point targeted by a complex regulatory network of kinases and phosphatases that allows for fine-tuning of plant reactive oxygen species (ROS) production by RBOHF in response to different stimuli and in diverse physiological processes.

TL;DR: A new set of 57 vectors that enable transgene expression in transiently or stably transformed cells and investigated the influence of CBL (Calcineurin B-like) protein expression on the subcellular localization of CIPKs, finding that induced co-expression of C BL3 is fully sufficient for dynamic translocation of C IPK5 from the cytoplasm to the tonoplast.

TL;DR: It is proposed that Ca2+-triggered CBL1/9-mediated activation of CIPK11 and subsequent phosphorylation of FIT shifts inactive into active FIT, allowing regulatory protein interactions in the nucleus and represents an environment-sensing mechanism to adjust nutrient uptake.
