March 2004 in “Proceedings of the National Academy of Sciences” This study reports that the DMI3 gene, essential for nodule formation in legume-rhizobial symbiosis, encodes a calcium/calmodulin-dependent protein kinase, highlighting its role in multiple plant symbioses.
March 2008 in “Faculty Opinions – Post-Publication Peer Review of the Biomedical Literature” This study found that a positive feedback loop involving RHD2, reactive oxygen species, and calcium ions helps maintain root hair growth sites and influences cell shape in Arabidopsis thaliana.

July 2018 in “FEBS letters” In this study, researchers identified the CBL1-CIPK26 Ca 2+ sensor-kinase complexes as key modulators of the NADPH oxidase RBOHC crucial for root hair differentiation in plants.
January 2025 in “Nature Communications” This study discovered that calcium dependent protein kinase 1 (CPK1) directly activates cyclic nucleotide-gated channels 5, 6, and 9, promoting root hair growth in Arabidopsis by regulating Ca²⁺ signaling.
