Project description:10-day-old wild-type and homozygous transgenic Arabidopsis seedlings (overexpressing OsTOP6A3 and OsTOP6B) grown under normal growth conditions were used for total RNA isolation. The 5 micrograms of each total RNA sample was processed for microarray analysis according to Affymetrix protocol. Keywords: Arabidopsis, wild-type and transgenic seedlings, differential gene expression

Project description:Glutathione S-transferases (GSTs) are the ubiquitous enzymes, which play important role in defense against various stresses. To analyze the function of a rice GST gene, OsGSTU4, we overexpressed it into Arabidopsis constitutively. The physiological analyses revealed that overexpression of GRX gene enhanced abiotic stress tolerance in transgenic plants as compared to wild-type. We used microarrays to study the global effect of overexpression of OsGSTU4 in Arabidopsis. Wild-type and transgenic Arabidopsis seedlings were grown on MS medium for 14-days in a culture room with a daily photoperiodic cycle of 16h light and 8h dark. The 500 ng of total RNA sample isolated from each tissue sample was processed for microarray analysis according to Affymetrix protocol. Two biological replicates for wild-type and GRX overexpression line were used for microarray analysis.
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.
