Project description:Arabidopsis brm plants depleted in a SWI/SNF-type ATPase BRM have decreased level of endogenous gibberellins and a phenotype that in many respects resembles the phenotype of mutants with repressed GA signaling or biosynthesis, like ga1-3. ga1-3/brm double mutant showed several additive and synergistic effects. To examine whether the phenotypic traits of brm, ga1-3 and ga1-3/brm lines are reflected at the gene expression level, we compared the expression profiles of brm, ga1-3, ga1-3/brm and wild-type plants using microarray analysis. Microarray analysis was performed on total RNA isolated from shoots of 18-d-old wt, brm, ga1-3, and ga1-3/brm seedlings. Three biological replicates were examined for each genotype. Plants were grown simultaneously under the same conditions.

Project description:Transcriptional profiling in the root between ga1, ga1 scl3 and ga1 SCL3 OE. We used Affymetrix ATH1 microarrays to determine the effect of GRAS transcription factor SCL3 and gibberellin on the growth and development of the Arabidopsis root system by global transcriptome analysis and to identify new regulators in the regulatory pathway.
