Project description:Transcriptional profiling of Arabidopsis rossette leaves comparing WT Col-0 with a transgenic line overexpressing AhERF or AhDOF genes from Amaranthus hypochondriacus under different conditions. Three-condition experiment of WT vs AhERF OE plant leaves. The analyzed conditions were: normal growth conditions, 5 days of water stress (no irrigation) and 24 hrs of recovery after watering water-stressed plants. Besides, a two-condition experiment where WT vs AhDOF OE plant leaves were compared. The experimental conditions were: normal growth conditions and plants watered with 40mL of 400mM NaCl solution for three straight days to produce salt stress.

Project description:Plants in temperate regions have evolved mechanisms to survive sudden temperature drops. Previous reports have indicated that the cold acclimation mechanism is light-dependent and does not fully operate under a low light intensity. In these studies, plants were grown under a long-day photoperiod and were more sensitive to freezing stress. However, winter annuals like Arabidopsis thaliana Col-0 germinate in the fall, overwinter as rosettes, and therefore must acclimate under short photoperiods and low irradiance. The role of light intensity was analysed in plants grown under a short-day photoperiod at the growth stage 1.14. Plants were acclimated at 4 °C for seven days under 100 and 20 μmol m-2s-1 PPFD for control and limited-light conditions, respectively. All cold acclimated plants accumulated molecular markers reportedly associated with acquired freezing tolerance, including proline, sucrose, CBFs, and COR gene protein products dehydrins and low-temperature-responsive proteins LTIs. Observed changes indicated that low PPFD did not inhibit the cold acclimation process, and the freezing stress experiment confirmed similar survival rates. The molecular analysis found distinct PPFD-specific adaptation mechanisms that were manifested in contrasting content of anthocyanins, cytokinin conjugates, abundances of proteins forming photosystems, and enzymes of protein, energy, and ROS metabolism pathways. Finally, this study led to the identification of putative proteins and metabolite markers correlating with susceptibility to freezing stress of non-acclimated plants grown under low PPFD. Our data show that Arabidopsis plants grown under short-day photoperiod can be fully cold-acclimated under limited light conditions, employing standard and PPFD-specific pathways.

Project description:Arabidopsis thaliana Col-0 plants were grown under different light conditions. Chloroplasts were isolated and their proteins extracted. Proteins were analysed by LC-MS and a label free quantification strategy was used to compare the different proteome compositions responsible for the respective acclimation.

Project description:The goal of this project is to compare the primary metabolite profile in different tissue types of the model plant Arabidopsis thaliana. Specifically, plants were grown hydroponically under the long-day (16hr light/day) condition at 21C. Tissue samples, including leaves, inflorescences, and roots were harvest 4 1/2 weeks post sowing. Untargeted primary metabolites profiling was carried out using GCTOF.

Project description:Plasma membrane proton pump maintains proton electrochemical gradient and provides energy to secondary transporters. Arabidopsis mutant plants with reduced proton pump activity grow normal under ideal growth conditions; however their growth are reduced compared with wildtype plants when placed under the conditions that stress on protonmotive force (high external pH or high external potassium).

Project description:Arabidopsis Col-0 seeds were germinated and grown for two weeks on Arabidopsis thaliana salt media (ATS, control) or ATS media supplemented 50, 75, 100 or 125 mM NaCl that imposes both an ionic and osmotic stress; or ATS media supplemented with iso-osmolar concentrations of sorbitol (100, 150, 200 or 250 mM) that imposes only an osmotic stress. The aim of the study was to identify genes involved in plant growth and adaptation to ionic stress compared to genes involved in growth and adaptation to osmotic stress conditions. To do this we identified lists of genes that are differentially expressed in plants grown in NaCl (A) and lists of genes differentially expressed in plants grown in sorbitol (B). We then compared these lists to find ionic/salt-specific genes that are only expressed in plants grown in NaCl and not in plants grown in sorbitol; and osmotic genes that are expressed both in plants grown in NaCl and in plants grown in sorbitol.

Project description:Plasma membrane proton pump maintains proton electrochemical gradient and provides energy to secondary transporters. Arabidopsis mutant plants with reduced proton pump activity grow normal under ideal growth conditions; however their growth are reduced compared with wildtype plants when placed under the conditions that stress on protonmotive force (high external pH or high external potassium). Seedlings of wildtype, aha1, and aha2 mutant plants were grown under ideal growth condition. Total RNA from those seedlings were subjected to transcriptome analyses using Affymetrix Gene Chip.
