The G protein-casein kinase 2 module acts as a pivot in plasma membrane-to-nucleus CLAVATA signaling to control shoot apical meristem size

The CLAVATA3 (CLV3)-WUSCHEL (WUS) feedback loop functions in shoot apical meristem maintenance. Liu et al. (2026) discovered that kinase Casein Kinase II act as nuclear effectors of G protein, linking CLV3 perception to WUS transcription.
