Expression
| EC Number | Organism | Comment | Expression |
|---|---|---|---|
| 1.14.18.10 | Artemisia annua | enzyme expression significantly gets down-regulated (up to about 5fold) under salinity conditions with 400 mM NaCl. The enzyme expression is clearly down-regulated after 3 h treatment with 150 mg/ml chitosan or after 6 h treatment with 0.3 mM methyl jasmonate or after 1.5 h treatment with 1 mM salicylic acid or after 1.5 h treatment with 1 mM trans-cinnamic acid | down |
| 1.14.18.10 | Artemisia annua | transcript levels of the enzyme are consistently increased upon 0.01 mM abscisic acid or 0.1 mM gibberellic acid treatment and induced to more than 2fold relative to the control seedlings. Osmotic/dehydration stress with 400 mM mannitol markedly induces the transcript levels during 6-9 h of treatment and decreases then after | up |
