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

ABSTRACT: 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

DEHYDRATION-RESPONSIVE ELEMENT BINDING PROTEIN2A (DREB2A) is a key transcription factor for drought and heat stress tolerance in Arabidopsis thaliana. DREB2A induces the expression of dehydration- and heat stress-inducible genes under the corresponding stress conditions. Target gene selectivity is assumed to require stress-specific posttranslational regulation, but the mechanisms of this process are not yet understood. Here, we identified DNA POLYMERASE II SUBUNIT B3-1 (DPB3-1), which was previo ...[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 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.

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.

Reactive leaf volatiles act as powerful inducers of abiotic stress-related gene expression [Agilent]

Project description:Abiotic stresses cause serious damage to plants; therefore, plants undergo a complicated stress response through signal transduction originating from environmental stimuli. Here we show that a subset of short-chain leaf volatiles with an M-NM-1,M-NM-2-unsaturated carbonyl bond in their structure (reactive short-chain leaf volatiles, RSLVs) like (E)-2-hexenal and (E)-2-butenal can act as signal chemicals that strongly induce the gene expression of abiotic-related transcription factors, such as heat stress-related transcription factors (HSFA2, MBF1c) and other abiotic stress-related transcription factors (DREB2A, ZATs). RSLV-induced expression of HSFA2 and MBF1c was eliminated in HSFA1s-, known as heat stress response master regulators, knockout mutant, whereas those of DREB2A and ZATs were not, suggesting that the RSLV signaling pathway is composed of HSFA1-dependent and -independent pathways. RSLV treatment induced production of chaperon proteins, and the RSLV-treated Arabidopsis thus demonstrated enhanced abiotic stress tolerance. Because oxidative stress treatment enhanced RSLV production, we concluded that commonly found RSLVs produced by environmental stresses are powerful inducer of abiotic stress-related gene expression as oxidative stress signals.
