propyl gallate/arabidopsis

Chlororespiration has been defined as a respiratory electron transport chain in interaction with photosynthetic electron transport involving both non-photochemical reduction and oxidation of plastoquinones. Different enzymatic activities, including a plastid-encoded NADH dehydrogenase complex, have

Radial expansion of root cells and elongation of root hairs were induced within 3 d of a massive dose (3 kGy) of gamma irradiation to Arabidopsis thaliana. Because treatment with the antioxidant n-propyl gallate before irradiation suppressed these changes, gamma irradiation partially rescued the

The plant-type ubiquinol:oxygen oxidoreductase, commonly called the alternative oxidase, is a respiratory enzyme thought to contain non-heme iron at its active site. To explore the structure of the enzyme by identifying amino acids involved in inhibitor-binding, a library of random mutants of the

We have presented changes in the photosynthetic apparatus activity of Arabidopsis thaliana plants occurring within 15-144 h of 100 microM Cu or Cd action with regard to jasmonate (JA) as well as expression of the oxidative stress and non-enzymic defense mechanisms. The inhibitory effect of both

The effects of short-term salt stress on gas exchange and the regulation of photosynthetic electron transport were examined in Arabidopsis (Arabidopsis thaliana) and its salt-tolerant close relative Thellungiella (Thellungiella halophila). Plants cultivated on soil were challenged for 2 weeks with

The Arabidopsis FAD7 gene encodes a plastid omega-3 fatty acid desaturase that catalyzes the desaturation of dienoic fatty acids in membrane lipids. The mRNA levels of the Arabidopsis FAD7 gene in rosette leaves rose rapidly after local wounding treatments. Wounding also induced the expression of
