Plant resistance to necrotrophic fungi is regulated by a complex set of signaling pathways that includes those mediated by the hormones salicylic acid (SA), ethylene (ET), jasmonic acid (JA), and abscisic acid (ABA). The role of ABA in plant resistance remains controversial, as positive and negative regulatory functions have been described depending on the plant-pathogen interaction analyzed. Here, we show that ABA signaling negatively regulates Arabidopsis (Arabidopsis thaliana) resistance to t ...[more]

Transcriptome profiling in two maize inbreds differing in cold-sensitivity.

Project description:We investigated effect of severe cold on transcriptome changes in two inbred maize lines, chilling-sensitive ETH-DL3 and chilling-tolerant ETH-DH7. Kernels were germinated in wet sand in darkness at 25C. Seedlings were transferred to growth chamber (day/night temperature 24/22C, photoperiod 14/10 h, light 250 umol quanta x m-2 x s-1) and grow in pots containing Knop's nutrient solution supplemented with Hoagland's micro-nutrients. After full development of the 3rd leaf (fully developed ligular region) plants were used in experiment. The experiment was begun at the start of the dark period. Half of the plants were transferred to cold chamber (day/night temperature 8/6C, photoperiod 14/10 h, light 250 umol quanta x m-2 x s-1) other half served as control (day/night temperature 24/22C, other parameters was the same as for cold treatment). After dark period (10h) and 200 minutes of light period samples were taken. Each sample consisted of the middle part of the 3rd leaf blade, pooled from three plants and frozen in liquid nitrogen. The experiment was replicated four times with two replications dye swapped.

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.

Yu_systemic light

Project description:Responsive genes in covered apex with light irradiation on rosette leaves are revealed by the expressional profiling. Normalized data is included as an additional file. It was created via the following protocol: The data were analyzed with Microarray Suite version 5.0 (MAS 5.0) using Affymetrix default analysis settings and global scaling as normalization method. The trimmed mean target intensity of each array was arbitrarily set to 500.

Transcription profiling by array of Arabidopsis thaliana plants to investigate the effect of heterologous expression of a soybean DREB2 gene (GmDREB2A;2)

Project description:Analysis of the effect of heterologous expression of a soybean DREB2 gene (GmDREB2A;2)on the transcriptome of transgenic Arabidopsis plants. For the genetic modification of Arabidopsis, we introduced gene casettes that express our genes of interest into the genome viaT-DNA transfer using Agrobacterium tumefaciens.

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

Project description: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.

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

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.

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.

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.
