| Outline of Final Research Achievements |
Group A Protein Phosphatase 2Cs (PP2Cs) function as key components in ABA signaling in response to osmotic stresses by regulating AREB/ABF transcription factors via SnRK2 protein kinases in Arabidopsis plants. Here, we show that group Aa PP2Cs such as ABI1 are involved in fundamental functions in plant survival, whereas group Ab PP2Cs, including HAI1, play an important role especially under osmotic stress conditions.
