Nature. 2009 Dec 3;462(7273):660-4. Epub 2009 Nov 18. Here we show that by combining the recently identified ABA receptor PYR1 with the type 2C protein phosphatase (PP2C) ABI1, the serine/threonine protein kinase SnRK2.6/OST1 and the transcription factor ABF2/AREB1, we can reconstitute ABA-triggered phosphorylation of the transcription factor in vitro. |

Proc Natl Acad Sci U S A. 2009 May 19;106(20):8380-5. Epub 2009 May 6. These SnRK2s, SnRK2.2, SnRK2.3, and SnRK2.6 (also known as OST1), are activated by ABA and can phosphorylate the ABA-responsive element binding factor family of b-ZIP transcription factors, which are important for the activation of ABA-responsive genes. |

Biochem J. 2009 Dec 10;424(3):439-48. In the present study, we have demonstrated that the C-terminal region of KAT1 acts as a phosphorylation target for the Arabidopsis -independent ABA (abscisic acid)-activated protein kinase SnRK2.6 (Snf1-related protein kinase 2.6). |

J Exp Bot. 2009;60(5):1439-63. Epub 2009 Jan 30. Indeed, the first regulatory enzymes underpinning these transport processes revealed genetically were several protein phosphatases of the 2C class and the OST1 kinase, a member of the SnRK2 family. |

Plant Physiol. 2004 Apr;134(4):1536-45. Epub 2004 Apr 2. Our results further indicate that JAR1, as OST1, functions upstream of ROS produced by NAD (P) H oxidases and that the cytoplasmic alkalization precedes ROS production during MJ or ABA signal transduction in guard cells. |

Proc Natl Acad Sci U S A. 2009 Dec 15;106(50):21425-30. Epub 2009 Dec 2. In response to drought stress the phytohormone ABA (abscisic acid) induces stomatal closure and, therein, activates guard cell anion channels in a -dependent as well as-independent manner. Two key components of the ABA signaling pathway are the protein kinase OST1 (open stomata 1) and the protein phosphatase ABI1 (ABA insensitive 1). |

Plant J. 2010 Mar 25. Leaf turgor of wild type plants responded to CO (2), light, humidity, ozone and abscisic acid (ABA) in a guard cell-specific manner. Under water stress the protein kinase OST1 activates the guard cell anion release channel SLAC1 and thereby triggers stomatal closure. |

19955427 | Lee SC, Lan W, Buchanan BB, Luan S: A protein kinase-phosphatase pair interacts with an ion channel to regulate ABA signaling in plant guard cells. Proc Natl Acad Sci U S A. 2009 Dec 15;106(50):21419-24. Epub 2009 Dec 2. The plant hormone abscisic acid (ABA) serves as a physiological monitor to assess the water status of plants and, under drought conditions, induces stomatal pore closure by activating specific ion channels, such as a slow-anion channel (SLAC1) that, in turn, mediate ion efflux from the guard cells. Here we show that the OST1 kinase interacts with the SLAC1 anion channel, leading to its activation via phosphorylation. |
