Project description:In this study we analyzed the effect of overexpression of an HA-tagged version of the ERF RAP2.12 on the transcriptome levels in aerobic and hypoxic-treated (O2 21% and 1%, respectively) Arabidopsis thaliana rosettes. We also analyzed the effect of a RAP2.12 and RAP2.2 simultaneous silencing in aerobic and hypoxic-treated (O2 21% and 1%, respectively) Arabidopsis thaliana rosettes. We treated Arabidopsis Col-0 (wt) rosettes and transgenic HA::RAP2.12 and amiRAP2.2-12 , 5-week old, grown in 8/16 light/dark photoperiod with: -Control (22°C, dark, 21% O2, 1.5h). -Hypoxia (22°C, dark, 1% O2, 1.5h).
Project description:HRE1 and HRE2 are two ERF transcription factors induced by low oxygen. In this work we analyzed the effect of ectopic expression of HRE1 and HRE2 on the arabidopsis transcriptome in aerobic and hypoxic (1% O2) conditions. While HRE1 has a moderate effect on the expression of anaerobic genes under hypoxia, HRE2 does not affect them either under aerobic or hypoxic conditions. Experiment Overall Design: We treated Arabidopsis seedling Col-0 (wt) and transgenic 35S::HRE1 and 35S::HRE2 , 7-day old, germinated in 12/12 light/dark photoperiod with: Experiment Overall Design: -Control (23°C, dark, 21% O2, 4h). Experiment Overall Design: -Hypoxia (23°C, dark, 1% O2, 4h). Experiment Overall Design: Two biological replicates for each condition.
Project description:Expression microarrays of WT vs. hog1D cells in aerobic or 5 hours of hypoxic growth (100% nitrogen gas). Two strains (WT vs. hog1 deletion), two conditions (aerobic vs. 5 hours hypoxic), two biological replicates each strain/condition.
Project description:Expression microarray experiments were performed to identify all of the aerobic and hypoxic transcripts in wild-type cells. The role of Hap1 in the regulation of transcription was examined by monitoring gene expression in hap1 deletion cells. Keywords: gene expression, strain comparison, response to hypoxic conditions
