Jasmonic acid and heavy metals in Arabidopsis plants - a similar physiological response to both stressors?

摘要: Summary Methyl ester of jasmonic acid (JAMe) in vivo conditions inhibited growth and pigment accumulation also decreased the efficiency some photosynthetic processes Arabidopsis plants. A similar effect excess Cu Cd ions, depending on their concentration, was observed. Salicylhydroxamate propyl gallate, inhibitors synthesis, prevented inhibitory heavy metals chlorophyll activity, but not that leaf (at a higher content) energy dissipative light-harvesting antennae. JAMe at 10−6 mol/L 10−5 showed protective against observed 10−4 mol/L. These results indicate strongly influences toxicity This is partially metal-specific depends concentration its internal or external origin.
