产品介绍： ABI1 is a key component and repressor of the abscisic acid (ABA) signaling pathway. It regulates numerous ABA responses, such as stomatal closure, osmotic water permeability of the plasma membrane, drought-induced resistance and rhizogenesis, response to glucose, high light stress, seed germination and inhibition of vegetative growth. Expressed in seeds and seedlings. Confined to lateral root caps and columella cells in roots. Induced by low temperature, drought, high salt, ABA and ethylene.? Activates/represses SnRK2.6/SRK2E/OST1 in response to ABA-dependent stimuli. Alternative names: ABI1, ABA INSENSITIVE 1, AtABI1, Protein phosphatase 2C 56, AtPP2C56, PP2C56.
