Project description:We found that Arabidopsis plants constitutively expressing OsRR6 exhibit reduced cytokinin sensitivity, adventitious root formation and enhanced anthocyanin accumulation. In addition they are hypersensitive to red, far-red and blue light in hypocotyl growth assay and also flower little early as compared to wild type.Therefore, to identify the downstream pathways affected in the OsRR6 overexpression plants, we performed transcriptome profiling of overexpression line vs wild type using Affymetrix microarray platform.
Project description:Homeobox transcription factors are known to regulate plant growth and development. Recently, they have also been implicated in abiotic stress responses. To analyze the role of HD-ZIP I subfamily member, OsHOX24, we constitutively overexpressed it in Arabidopsis. The physiological analyses revealed that overexpression of OsHOX24 gene severely reduced abiotic stress tolerance in transgenic plants as compared to wild-type. We used microarrays to study the global effect of OsHOX24 overexpression in Arabidopsis under control condition.
Project description:Transcription profiling by array of Arabidopsis MKK9DD (constitutively active MKK9 kinase mutant) overexpressing seedlings and Pi-starved wild type seedlings to identify the same regulated genes
Project description:To identify genes acting downstream of MAP kinase kinase, and thus map its signal, we used the steroid-inducible overexpression system. The constitutive active form MKK3 (MKK3DD) or MKK4 (MKK4DD) was cloned into the glucocorticoid-inducible vector pTA7002 and transformed using Agrobacterium method into Arabidopsis Col-0 plants. The transgenic plants transformed empty vector was used as control plants (Cont).
