Affymetrix Arabidopsis ATH1 Genome Array (ath1121501)
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.

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.
Publication Title
A genome-wide analysis of the effects of sucrose on gene expression in Arabidopsis seedlings under anoxia.

- Arabidopsis Gene 1.1 ST Array (aragene11st)
Description
The effect of the overexpression of a stabilized version of the transcription factor RELATED TO APETALA2.12 (RAP2.12) on the transcriptome of Arabidopsis rosettes was investigated. To this purpose, 4-week old rosette of wild-type and 35S:13RAP2.12 plants were compared. Samples were composed of pools of 3 plants.

- Affymetrix Arabidopsis ATH1 Genome Array (ath1121501)
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.
Publication Title
HRE1 and HRE2, two hypoxia-inducible ethylene response factors, affect anaerobic responses in Arabidopsis thaliana.

- Affymetrix Arabidopsis ATH1 Genome Array (ath1121501)
Description
This study analyzes transcriptomic data of Arabidopsis thaliana Col-0 and overexpression lines of Hypoxia Response Attenuator (HRA1; At3g10040) with Col-0 background (OE-HRA1). Two independent transgenic lines of OE-HRA1 were considered as biological replicates (OE-HRA1#1 and OE-HRA1#2). Seven-day-old seedlings were treated either with or without hypoxia (low oxygen) stress for 2 hours. This dataset includes CEL files, RMA signal values and MAS5 P/M/A calls from total mRNA populations. Quantitative profiling of cellular mRNAs was accomplished with the Affymetrix ATH1 platform.

- Affymetrix Arabidopsis ATH1 Genome Array (ath1121501)
Description
We treated Arabidopsis seedlings with chitosan and carried out a transcript profiling analysis (GeneChip microarrays) in order to identify genes and transcription factors regulated by chitosan. The results showed that jasmonate and defense responsive genes, camalexin and lignin biosynthetic genes were among genes up-regulated by chitosan. Several transcription factors are also strongly induced by chitosan.

- Affymetrix Rice Genome Array (rice)
Description
Rice (Oryza sativa L.) seeds can germinate in complete absence of oxygen. Under anoxia, the rice coleoptile elongates, reaching a length greater than that of the aerobic one. In this series, we compare the transcriptome of rice coleoptiles grown under aerobic and anaerobic conditions.
Publication Title
Transcript profiling of the anoxic rice coleoptile.
