Stress Induced Calcium Signaling Facilitates ABA Mediated Transcriptional Adaptation
Ontology highlight
ABSTRACT: ABA and calcium both function as central signals in developmental programs and environmental responses. Little is known about the way how both messengers functionally interact. Here we report that stress induced calcium signatures are essential and likely sufficient for inducing ABA accumulation in roots. Moreover, we show that calcium activated calcium sensor/kinase complexes directly phosphorylate and activate ABA responsive transcription factors. Our results reveal a molecular mechanism that allows for integrating, fine tuning and termination of hormonal and calcium signaling on the level of gene transcription.
