Elevated CO induce alterations in the hormonal regulation of stomata in drought stressed tomato seedlings.

The atmospheric CO level is rising, and the consequent climate change is causing an increase in drought events. Furthermore, the CO level is known to induce changes in the physiological responses to stress in plants. Exogenous melatonin is suggested to play roles in the response of plants to abiotic stresses, including drought.

Identification of Azoxystrobin Glutathione Conjugate Metabolites in Maize Roots by LC-MS.

Xenobiotic detoxification in plant as well as in animals has mostly been studied in relationship to the deactivation of the toxic residues of the compound that, surely for azoxystrobin, is represented by its β-methoxyacrylate portion. In maize roots treated for 96 h with azoxystrobin, the fungicide accumulated over time and detoxification compounds or conjugates appeared timewise. The main detoxified compound was the methyl ester hydrolysis product (azoxystrobin free acid, 390.
