Arabidopsis thaliana | APR mRNA levels of all three isoforms increase 3fold in roots after 5 h of treatment with 150 mM NaCl. In mutants deficient in cytokinin and auxin, jasmonate, salicylate, or ethylene signaling APR mRNA levels are increased upon salt exposure similar to wild type plants, however, APR enzyme activity is not affected by salt in these plants. Signaling via gibberellic acid is essential for the increase in APR mRNA by salt treatment. Addition of 0.1 mM salicylate to the nutrient solution leads to an increase of mRNA levels of all three APR isoforms. 0.2 mM 1-aminocyclopropane carboxylic acid and 0.045 mM jasmonate increase accumulation of APR1 and APR3 transcripts, but do not affect the APR2 isoform. | up |
