Transcription profiling of Arabidopsis VCS-amiRNA plants under a dehydration stress condition

ABSTRACT: Transcriptional profiles were compared between wild type and the VCS-amiRNA plants under a dehydration stress condition. VCS-amiRNA plants are VCS (VARICOSE)-knockdown Arabidopsis plants expressing an artificial miRNA (ami-RNA) construct for VCS. VCS-amiRNA plants showed a reduction in VCS gene expression to approximately 40% of that of wild type plants.

Rapid changes in messenger RNA population are vital for plants to properly exert multiple adaptive responses under continuously changing stress conditions. Transcriptional activation mediated by the 'abscisic acid (ABA)-activated SnRK2 protein kinases-ABA-responsive element (ABRE)-binding proteins/ABRE-binding factors (AREB/ABFs)' signalling module is a crucial step in the expression of stress-inducible genes under osmotic stress conditions in Arabidopsis<sup>1-4</sup>. In addition to transcript ...[more]

Transcription profiling under heat stress of transgenic Arabidopsis lines in which expression of BPMs were suppressed by an amiRNA

Project description:BPMs are a family of E3 ubiquitin ligases. We identified BPM proteins as interactors of the Arabidopsis stress responsive transcription factor DREB2A. We found an increase in the accumulation level of the DREB2A protein under heat stress in transgenic Arabidopsis plants in which expression of six BPMs were suppressed by an amiRNA. In order to evaluate the impacts of the amiRNA on the gene expression under heat stress, transcriptomes were compared between these transgenic plants and vector control plants.

Transcription profiling of OsPIL1/DREB1A double-overexpressing Arabidopsis lines.

Project description:To improve both drought stress tolerance and growth of plants, we generated transgenic Arabidopsis plants that overexpress two transcription factors: DREB1A and OsPIL1. It was reported that DREB1A improves drought stress tolerance in various crops but causes dwarfism, and OsPIL1 enhances cell elongation through activation of cell wall synthesis in rice. We performed microarray experiments using a single overexpressor of OsPIL1 and the double overexpressor of DREB1A and OsPIL1 to study the potential interactions of the gene networks regulated by the two transcription factors in the double overexpressor.

Project description:To improve both drought stress tolerance and growth of plants, we generated transgenic Arabidopsis plants that overexpress DREB1A and GA5. It was reported that DREB1A improves drought stress tolerance in various crops but causes dwarfism, and GA5 encodes a GA synthetic enzyme which enhances plant growth. We performed microarray experiments using a single overexpressor of GA5 and the double overexpressor of DREB1A and GA5 to study the potential interactions of the gene networks regulated by the two factors in the double overexpressor.

Transcription profiling of Arabidopsis thaliana hsc70-1/2/3 triple mutant under salt stress

Project description:HSC70 is the cytosolic isoform of plant HSP70. We have found that HSC70 family proteins bind to the heat shock transcription factor A1s (HsfA1s), which are the master regulators of the heat shock response in plants, and suppress their activity. We additionally found that the triple knock out of HSC70s alters responses of Arabidopsis plants to salt stress. To investigate the role of the HSC70s in salt stress responses, we evaluated the effects of the triple knock out on the transcriptome under salt stress.

Project description:HSC70 is the cytosolic isoform of plant HSP70. We have found that HSC70 family proteins bind to the heat shock transcription factor A1s (HsfA1s), which are the master regulators of the heat shock response in plants, and supress their activity. To investigate the role of HSC70s in the regulation of HsfA1s and heat shock responses, we evaluated the effect of triple knock out of HSC70s on the transcriptome under the normal growth condition.

Transcription profiling of a transgenic Arabidopsis seedling that expresses a constitutively active form of HsfA1d

Project description:HsfA1d is one of the three master regulators (HsfA1s; HsfA1a, b and d) in the heat stress response of Arabidopsis thaliana. The protein levels of these HsfA1s are steady before and after heat stress, suggesting the existence of post-translational regulation. Through analyses of a deletion series of the HsfA1d protein, we identified a regulatory domain in this protein. The deletion of this domain turned the HsfA1d protein into an active form, and its expression resulted in induction of heat stress-inducible genes at room temperature. This microarray experiment was conducted to identify genes that are regulated by the function of the newly identified regulatory domain of HsfA1d.
