Abstract excerpt

Calcium-dependent protein kinases decode cellular calcium transients and play diverse roles in plant growth and stress responses. In Arabidopsis thaliana, AtCPK28 contributes to immune homeostasis by phosphorylating subgroup IV plant U-box proteins, which target the key immune receptor-like cytoplasmic kinase AtBIK1 for turnover. Here, we present functional analysis of MpCPK28 in the liverwort Marchantia...
