Project description:The proper accumulation of BBX22 mediated by COP1 is crucial for plants to maintain better growth fitness when growing in the dark environment as well as responding to seasonal changes in day-length. The constitutive-photomorphogenic development of the cop1 mutant is enhanced in cop1BBX22-GFPox plants, which show a short hypocotyl, high anthocyanin accumulation and expression of light-responsive genes. Target genes responsible for the exaggerated light phenotype in cop1BBX22-GFPox plants were revealed by comparing transcriptomes among dark-grown wild-type, cop1 and cop1BBX22-GFPox plants. Expression of genes regulated by light and multiple hormones are altered in plants over-accumulating BBX22, implying a coordination role of BBX22 in light- and hormone-mediated seedling development.

Three biological replicates for 4-day-old etiolated seedlings of wild type (Col-0) and two mutants (cop1-4 and cop1-4BBX22-GFPox).

Project description:Arabidopsis AP1-GR ap1-1 cal-1 were grown under long-day (16 h light/8 h dark) condition. After bolding (26 DAG), half of the plants were treated with dexamethasone. 31 DAG, the untreated inflorescenes were sampled as t0 and the dexamethasone treated one as t5.

Project description:How do the transcript levels of leaf-expressed genes change in a normal day-night cycle? The interest is in genes that are regulated by the circadian clock and the diurnal component (i.e. light, metabolite changes). Plants were grown on soil in a 12/12 h light/dark rythm at 20°C day and night. 5 weeks after germination the rosettes of the non-flowering plants were harvested, 15 plants per sample. Plants were harvested at 6 timepoints every 4 hours beginning with the end of the night (still in darkness). Keywords: repeat

Project description:Although many regulatory components of light signaling have been functionally characterized, only a few of them have been reported to cross talk with other signaling cascades. In this study, we have analyzed the expression profiles of Arabidopsis genes in wild-type, atmyc2 mutant, cop1-6 mutant, and atmyc2 cop1-6 double mutant seedlings grown under constant dark, constant blue-light, and constant blue-light along with abscisic acid (ABA) to illustrate the interplay of negative regulators, AtMYC2 and COP1, in light and ABA signaling Keywords: Light and abscisic acid treatment Expression data for wild-type, atmyc2, cop1-6, and atmyc2 cop1-6 seedlings under constant dark, blue-light and blue-light along with abscisic acid Ten-day-old Arabidopsis (wild-type, atmyc2 mutant, cop1-6 mutant, and atmyc2 cop1-6 double mutant) seedlings grown under constant dark, constant blue-light (35 µmol/sec/m2), and constant blue-light along with ABA (0.5 µm) were used for RNA extraction and hybridization on Affymetrix microarrays. Two biological replicates of each sample were used for microarray analysis.
