Measurements of chlorophyll a fluorescence, nutrient and trace elements, total protein content and malonyldialdehyde in leaves of Arabidopsis thaliana between 1 and 192 h after treatment with 0, 1 or 3 mM 2-3H-benzoxazolinone (BOA), together with imaging of chlorophyll a fluorescence and of the distributions of hydrogen peroxide and superoxide anion,(More)
Based on previous results, which showed that the secondary metabolite citral causes disturbances to plant water status, the present study is focused on demonstrating and detailing these effects on the water-related parameters of Arabidopsis thaliana adult plants, and their impact on plant fitness. Clear evidence of effects on water status and fitness were(More)
Temperature changes and salt accumulation are among the most common abiotic factors affecting plants in agricultural and natural ecosystems. The different responses of plants to these factors have been widely investigated in previous works. However, detailed mechanism of the early photosynthetic response (first 24 h) has been poorly studied. The aim of the(More)
We investigated the effects of the secondary metabolite protocatechualdehyde (PCA, 3,4-dihydroxybenzaldehyde) on stress markers, including fluorescence parameters and the concentrations of pigments, free radicals, protein, and lipid peroxides, in adult plants of Arabidopsis thaliana. The content of proline, carotenoids, and chlorophylls a and b peaked 9 h(More)
