GRF1 fine‐tunes the copper‐responsive transcription module of CPK3‐bHLH107 by manipulating interaction and phosphorylation
SUMMARY Previously, the crucial role of calcium‐dependent protein kinase 3 (CPK3) in Cu2+‐triggered immunity (CuTI) has been established in Arabidopsis. CPK3 promotes the phosphorylation of basic helix–loop–helix 107 (bHLH107), thereby activating the expression of 1‐aminocyclopropanecarboxylic acid synthesis 8 (ACS8) a...
