Name | OPEN STOMATA 1 | Brief Description | Protein kinase superfamily protein |
TAIR Computational Description | Protein kinase superfamily protein;(source:Araport11) |
TAIR Curator Summary | Encodes calcium-independent ABA-activated protein kinase, a member of SNF1-related protein kinases (SnRK2) whose activity is activated by ionic (salt) and non-ionic (mannitol) osmotic stress. Mutations disrupted ABA induction of stomatal closure as well as ABA inhibition of light-induced stomatal opening. However, regulation of stomatal opening/closing by light or CO(2) is not affected in these mutants. May act in the interval between ABA perception and reactive oxygen species production in the ABA signalling network. |
