Affymetrix Arabidopsis ATH1 Genome Array (ath1121501)
Description
TranscriptoTranscriptome profiling using DNA microarrays of the aerial parts of the wild-type and other plants was conducted to examine if either MYB overexpression or flavonoid overaccumulation is responsible for the expression of stress-related genes involved in both the biotic and abiotic stress response.
Publication Title
Enhancement of oxidative and drought tolerance in Arabidopsis by overaccumulation of antioxidant flavonoids.

- Affymetrix Arabidopsis ATH1 Genome Array (ath1121501)
Description
Due to ever increasing environmental deterioration it is likely that influx of solar UV-B radiation (280-320 nm) will increase further due to the depletion of stratospheric ozone. Given this fact it becomes essential that we better understand both rapid and adaptive responses of plants to UV-B imposed stress. Here we compare the transcriptmic responses of wild type Arabidopsis to that of Arabidopsis mutants impaired in flavonoid (TRANSPARENT TESTA4 [tt4] or sinapoyl-malate (sinapoylglucose accumulator 1 [sng1]) biosynthesis, to a short, 24h exposure to this photo-oxidative stress. In control experiments we subjected the same genotypes to 24h treatments of continuous light.

- Affymetrix Arabidopsis ATH1 Genome Array (ath1121501)
Description
Aerial parts of the rice-Arabidopsis FOX (Full-length cDNA overexpressor) lines K16331 and K19624 harboring the rice FL cDNA of LBD37 (Os-LBD37) were analyzed. LBD37 belongs to the plant- specific LOB- (Lateral Organ Boundary) domain family proteins first characterized in Arabidopsis. Results point towards an involvement of the rice LBD37 ortholog of Arabidopsis in nitrogen metabolism- related processes.

Affymetrix Arabidopsis ATH1 Genome Array (ath1121501)
Description
The 5th and 6th leaf blades of the rice Os-LBD37 overexpressor line RK16331-13 and the empty vector control line FOX3 were examined. LBD37 belongs to the plant- specific LOB- (Lateral Organ Boundary) domain family proteins first characterized in Arabidopsis. Results point towards an involvement of the rice LBD37 (OsLBD37) ortholog of Arabidopsis in nitrogen metabolism- and senescence- related processes.

- Affymetrix Mouse Genome 430 2.0 Array (mouse4302)
Description
The adult mammalian brain is composed of distinct regions that have specialized roles. The BF/POA regions are thought to have an important role in the regulation of sleep/wake behavior. However, genetic markers of the responsible cells for the regulation of sleep/wake behavior are largely unknown. To identify the molecular markers of the BF/POA regions, we sampled the BF/POA regions and compared gene expression in the BF/POA regions with those of other brain regions which we previously reported in the BrainStars (B*) project, in which we sampled ~50 small brain regions, including sensory centers and centers for motion, time, memory, fear, and feeding.

Description
The adult mammalian brain is composed of distinct regions that have specialized roles. To dissect molecularly this complex structure, we conducted a project, named the BrainStars (B*) project, in which we sampled ~50 small brain regions, including sensory centers and centers for motion, time, memory, fear, and feeding. To avoid confusion from temporal differences in gene expression, we sampled each region every 4 hours for 24 hours, and pooled the sample sets for DNA-microarray assays. Therefore, we focused only on spatial differences in gene expression. We then used informatics to identify candidates for (1) genes with high or low expression in specific regions, (2) switch-like genes with bimodal or multimodal expression patterns, and (3) genes with a uni-modal expression pattern that exhibit stable or variable levels of expression across brain regions. We used our findings to develop an integrated database (http://brainstars.org/) for exploring genome-wide expression in the adult mouse brain.
