Organism | Comment | Expression |

Arabidopsis thaliana | enzyme expression is down-regulated by exposure to drought (15%) and NaCl (43%). mRNA levels are also reduced by growth in the dark to 62%. Jasmonic acid treatment slightly decreases (20%) the level of mRNA after 8 h treatment | down |
Arabidopsis thaliana | no substantial change in level occurs by exposure to UV irradiation | additional information |
Arabidopsis thaliana | enzyme expression is up-regulated by light, heat shock (80% within 1 h), absicsic acid (43% after 4 h) and ethylene treatments (33% after 8 h) | up |
