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

ABSTRACT: 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.

Transcriptional profiling of Arabidopsis thaliana hsc70-1/2/3 triple mutant

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 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.

Transcript profiling of NF-YC10-overexpressing Arabidopsis seedlings under heat stress

Project description:NF-YC10 is a subunit of the NF-Y transcription factor complex in Arabidopsis thaliana. We identified NF-YC10 as an interactor of the transcription factor DREB2A, which binds to DRE and activate expression of target genes under heat and/or dehydration stress conditions. Transgenic Arabidopsis plants that overexpress NF-YC10 showed stronger expression of DREB2A target genes under heat stress and were more tolerant to heat stress tolerance than the vector control plants. We conducted a transcript profiling by microarray aiming to identify target genes of NF-YC10 under heat stress

Differential regulation of HSFA1s and HSFA2 after heat shock in Arabidopsis

Differential regulation of HSFA1s and HSFA2 after heat shock in Arabidopsis

Project description:HSFA1s are a gene family of HSFA1 with four members, HSFA1a, HSFA1b, HSFA1d, and HSFA1e. HSFA1s are the master regulators of heat shock response. As a part of the heat shock response, HSFA2 can prolong the heat shock response and amplify the heat shock response in response to repeat heat shock. To identify the heat-shock-responsive genes differentially regulated by HSFA1s and HSFA2, we compared the transcriptomic differences of plants containing only constitutively expressed HSFA1s or HSFA2 after heat stress. hsfa2 (the KO mutant of HSFA2, Col-0 background) and A2QK-10 (CaMV 35S:HSFA2 in QK mutant; QK is HSFA1a/b/d/e quadruple KO mutant) were used to compare the difference of heat shock response when plants lack HSFA1s or HSFA2. The aim is to find the HSFA1s- and HSFA2-preferred regulating genes after heat stress. As the control samples, wild type is the plant with normal heat shock response, and QK (HSFA1s KO mutant, Col-0 and Ws mixed background) is the plant that lost the heat shock response controlled by HSFA1s.

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.
