1 Expression of the abi1-1 dominant mutation blocked accumulation of the drought-induced TAS14 and LE25 mRNAs in response to ABA, as well as ABA- and wound-induced expression of the defense-associated pin2 and LAP transcripts. Abscisic Acid Protein phosphatase 2C family protein Arabidopsis thaliana
2 Expression of the abi1-1 dominant mutation blocked accumulation of the drought-induced TAS14 and LE25 mRNAs in response to ABA, as well as ABA- and wound-induced expression of the defense-associated pin2 and LAP transcripts. Abscisic Acid Protein phosphatase 2C family protein Arabidopsis thaliana
3 These results indicate that abi1-1 inhibits wound-induced expression of the pin2 and LAP transcripts by blocking ABA-induction of these genes. Abscisic Acid Protein phosphatase 2C family protein Arabidopsis thaliana
4 This implicates ABI1 in wound-signalling and suggests that a common early ABA signalling pathway may function in the responses to wounding and water stress. Abscisic Acid Protein phosphatase 2C family protein Arabidopsis thaliana
