Key findings
Among 34 Arabidopsis CDPKs, CPK3 and CPK6 function in ABA-activated S-type anion and Ca²⁺-permeable channels.
Methodology
Identified guard-cell CDPKs, isolated cpk3/cpk6 mutants, and measured ion-channel and stomatal responses to ABA.
Limitations
Does not map every CDPK substrate in all cell types.
