TranscriptomicsTranscription profiling of Arabidopsis wild-type, thylakoidal ascorbate peroxidase overexpressor (over tAPX, line 14/2), flu mutant and flu plants overexpressing thylakoidal ascorbate peroxidase
We used the flu mutant of Arabidopsis and a transgenic line that overexpresses the thylakoid-bound ascorbate peroxidase (tAPX) to address the interactions between different reactive oxygen species (ROS) signaling pathways. The conditional flu mutant of Arabidopsis accumulates excess protochlorophyll...

TranscriptomicsTranscription profiling of Arabidopsis thaliana (Ler) rosette leaves treated with paraquat (methyl viologen)
We used microarrays to detail Arabidopsis gene expression in response to paraquat, a herbicide that acts as a terminal oxidant of photosystem I that in the light leads to the enhanced generation of superoxide and hydrogen peroxide inside plastids. Within a few hours after paraquat treatment changes ...

TranscriptomicsTranscription profiling of Arabidopsis thaliana (Ler) rosette leaves after the release of singlet oxygen inside plastids
We used the flu mutant of Arabidopsis to detail gene expression in response to singlet oxygen. The conditional flu mutant of Arabidopsis accumulates excess protochlorophyllide in the dark within chloroplast membranes that upon illumination acts as a photosensitizer and generates singlet oxygen. Imme...

TranscriptomicsTranscription profiling by array of Arabidopsis wild type and topoIV mutant plants at the end of a dark period and after re-illumination
A topoisomeras IV mutant in a flu background was identified in a mutant screen for ectopic activation of a reporter for singlet oxygen release. Gene expression was profiled on AGRONOMCS1 microarrays for wild type and the topoIV mutant at the end of an 8h dark period and after 30min of re-illuminatio...
