  ABSTRACT: Transgenic tomato lines (cv. Kashi Vishesh) over-expressing AtDREB1A/CBF3 driven by stress-inducible rd29A promoter showed significantly higher activities of key antioxidant enzymes when exposed to water-deficit for 7, 14, and 21 days. Transgenic tomato plants exposed to water-deficit recorded lower levels of hydrogen peroxide and superoxide anion formation compared to the non-transgenic plants, suggesting alleviation of reactive oxygen species (ROS). A significant increase in activities of enzymes superoxide dismutase (SOD), catalase (CAT), ascorbate peroxidase (APX), glutathione reductase (GR), dehydroascorbate reductase (DHAR), and monodehydroascorbate reductase (MDHAR) was observed in response to the different durations of water-deficit conditions. In contrast, enzyme guaiacol peroxidase (POD) activity was lower in the transgenic lines and showed a negative correlation with ROS, ascorbic acid (AsA), and glutathione levels. The concentrations of AsA, glutathione and their reduced forms were higher in the transgenic plants and increased with ROS levels. These results indicate that AtDREB1A transgenic tomato lines are better adapted to water-deficit as they showed lower drought-induced oxidative stress due to activation of the antioxidant response.

  ABSTRACT: Genotoxic stress caused by a variety of chemical and physical agents may lead to DNA breaks and genome instability. Response to DNA damage depends on ATM/ATR sensor kinases and their downstream proteins, which arrange cell cycle checkpoints. Activation of ATM (ataxia-telangiectasia-mutated)/ATR (ATM and Rad 3-related) signaling pathway triggers cell cycle arrest (by keeping cyclin-Cdk complexes inactive), combined with gamma-phosphorylation of histone H2A.X and induction of DNA repair processes. However, genotoxic stress activates also mitogen-activated protein kinases (MAPKs) which may control the functions of checkpoint proteins both directly, by post-translational modifications, or indirectly, by regulation of their expression. Our results indicate that in root meristem cells of Vicia faba, MAP kinase signaling pathway takes part in response to hydroxyurea-induced genotoxic stress. It is shown that SB202190, an inhibitor of p38 MAP kinase, triggers PCC (premature chromosome condensation) more rapidly, but only if cell cycle checkpoints are alleviated by caffeine. Since SB202190 and, independently, caffeine reduces HU-mediated histone H4 Lys5 acetylation, it may be that there is a cooperation of MAP kinase signaling pathways and ATM/ATR-dependent checkpoints during response to genotoxic stress.

  ABSTRACT: Abstract Cotton genotype RAHS 187 was analyzed for changes in physiology, biochemistry and proteome due to drought stress. The deleterious effect of drought in cotton plants was mainly targeted towards photosynthesis. The gas-exchange parameters of net photosynthesis (A), stomatal conductance (gs) and transpiration (E) showed a decreasing trend as the drought intensity increased. The fluorescence parameters of, effective quantum yield of PSII (ΦPSII), and electron transport rates (ETR), also showed a declining trend. As the intensity of drought increased, both H2O2 and MDA levels increased indicating oxidative stress. Anthocyanin levels were increased by more than four folds in the droughted plants. Two-dimensional gel electrophoresis detected more than 550 protein spots. Significantly expressed proteins were analyzed by peptide mass fingerprinting (PMF) using MALDI-TOF-TOF. The number of up-regulated spots was found to be 16 while 6 spots were down-regulated. The reasonable implications in drought response of the identified proteins vis-à-vis physiological changes are discussed. Results provide some additional information that can lead to a better understanding of the molecular basis of drought-sensitivity in cotton plants.
