Project description:Anoxia induces several heat shock proteins and a heat pre-treatment can acclimatize Arabidopsis seedlings to a subsequent anoxic treatment. In this work we analyzed the response of Arabidopsis seedlings to anoxia, heat and a combined heat+anoxia stress. A significant overlapping between the anoxic and heat shock responses has been observed by whole-genome microarray analysis. Experiment Overall Design: We treated Arabidopsis seedling, 4-days old, dark germinated with: Experiment Overall Design: -Control (23°C, dark, liquid Murashige-Skoog medium containing 30mM sucrose). Experiment Overall Design: -Heat-treated (38°C for 90 minutes, dark, liquid Murashige-Skoog medium containing 30mM sucrose). Experiment Overall Design: -Anoxia-treated (23°C, under anoxia for 6h, dark, liquid Murashige-Skoog medium containing 30mM sucrose). Experiment Overall Design: -combined heat+Anoxia-treatment (23°C, treated at 38°C for 90 min and thereafter under anoxia for 6h, dark, liquid Murashige-Skoog medium containing 30mM sucrose). Experiment Overall Design: Two biological replicates for each condition.
Project description:Arabidopsis thaliana ecotype Columbia glabra were grown for 4 days in the dark without added sucrose. Samples were subsequently kept for 6h either [1] under aerobic conditions, [2] under anoxia in absence of sucrose or [3] under anoxia in presence of sucrose.

Project description:Arabidopsis thaliana ecotypes Columbia (Col-0) (wild type: WT) was used in this study. After sterilization, the seeds were placed on Murashige and Skoog medium supplemented with 2% (w/v) sucrose for 10 days and then the seedling were transferred to soil under 16 hours light (22°C) / 8 hours dark (18°C) period in growth chamber at a light intensity of 120?150 µmol m-2 s-1. 20-day-old Arabidopsis leaves without bolting were immediately frozen in liquid nitrogen for RNA and protein and metabolites extraction. Leaves were harvested at three different time points: t = 0 hr (end of night), t = 1 hr (one hour after light turn on) and t = 8 hr (eight hours after light turn on), respectively.
