Transcription profiling of Arabidopsis wild type and areb1 areb2 abf3 abf1 quadruple mutant seedlings

ABSTRACT: Total RNA was isolated with RNAiso regent (Takara) from 12-day-old seedlings of the areb1 areb2 abf3 abf1 quadruple mutant and WT plants grown on GM agar plates with or without treatment of 50 uM ABA, dehydration stress, or 250 mM NaCl for 6 h.

Four Arabidopsis AREB/ABF transcription factors function predominantly in gene expression downstream of SnRK2 kinases in abscisic acid signalling in response to osmotic stress.

Under osmotic stress conditions such as drought and high salinity, the plant hormone abscisic acid (ABA) plays important roles in stress-responsive gene expression mainly through three bZIP transcription factors, AREB1/ABF2, AREB2/ABF4 and ABF3, which are activated by SNF1-related kinase 2s (SnRK2s) such as SRK2D/SnRK2.2, SRK2E/SnRK2.6 and SRK2I/SnRK2.3 (SRK2D/E/I). However, since the three AREB/ABFs are crucial, but not exclusive, for the SnRK2-mediated gene expression, transcriptional pathways ...[more]

Transcription profiling of wo independent Arabidopsis lines 35S-AREB1deltaQT under non-stress conditions with that of wild type plants

Project description:AREB1deltaQT is a constitutively active form of AREB1, an abscisic acid (ABA)-responsive element binding protein (Uno et al., 2000, PNAS 97: 11632-11637). AREB1 is a bZIP transcription factor in Arabidopsis plants (Col). transcription of the AREB1 gene is upregulated by drought, NaCl, and ABA treatment in vegetative tissues. Because expression of the intact AREB1 gene on its own is insufficient to lead to expression of downstream genes under normal growth conditions, we created an activated form of AREB1 (AREB1deltaQT) to overcome the masked transactivation activity of AREB1. In this experiment, to help to identify target genes of AREB1, we compared the expression profiles in two independent lines 35S-AREB1deltaQT plants under non-stress conditions with that of wild-type plants by using Agilent near-full-genome gene chips (Arabidopsis 22K).

Transcriptional profiling of Vitis vinifera during grapevine-downy mildew interaction using cDNA microarrays

Project description:Study of gene expression during Plasmopara viticola infection in the resistant Vitis vinifera cultivar 'Regent'. The oomycete fungus Plasmopara viticola (Berk. et Curt.) Berl. et de Toni is responsible for grapevine downy mildew disease. Most of the cultivated grapevines are sensitive to this pathogen, thus requiring intensive fungicide treatments. The molecular basis of resistance to this pathogen is poorly understood. We have carried out a cDNA microarray transcriptome analysis to identify grapevine genes associated with resistance traits. Early transcriptional changes associated with downy mildew infection in the resistant Vitis vinifera cultivar ‘Regent’, when compared to the susceptible cultivar ‘Trincadeira’, were analyzed. Transcript levels were measured at three time-points: 0, 6 and 12 hours post inoculation (hpi). Our data indicate that resistance in V. vinifera ‘Regent’ is induced after infection. This study provides the identification of several candidate genes that may be related to ‘Regent’ defense mechanisms, allowing a better understanding of this cultivar's resistance traits.

Transcription profiling of Arabidopsis thaliana seedlings wild type vs transgenic plants under drought stress

Project description:Plants engineered for abiotic stress tolerance may soon be commercialized. The engineering of these plants typically involves the manipulation of complex multigene networks and may therefore have a greater potential to introduce pleiotropic effects than the simple monogenic traits that currently dominate the plant biotechnology market. Drought- tolerant Arabidopsis thaliana were engineered through overexpression of the transcription factor ABF3 in order to investigate unintended pleiotropic effects. In order to eliminate position effects, the Cre/lox recombination system was used to create control plant lines that contain identical T-DNA insertion sites but with the ABF3 transgene excised. This additionally allowed us to determine if Cre recombinase can cause unintended effects that impact the transcriptome. Microarray analysis of control plant lines that underwent Cre-mediated excision of the ABF3 transgene revealed only two genes that were differentially expressed in more than one plant line, suggesting that the impact of Cre recombinase on the transcriptome was minimal. In the absence of drought stress, overexpression of ABF3 had no effect on the transcriptome, but following drought stress, differences were observed in the gene expression patterns of plants overexpressing ABF3 relative to control plants. Examination of the functional distribution of the differentially expressed genes revealed strong similarity indicating that unintended pathways were not activated. In response to drought stress, overexpression of ABF3 results in a reprogramming of the drought response, which is characterized by changes in the timing or strength of expression of some drought response genes, without activating any unexpected gene networks. These results illustrate that important gene networks are highly regulated in Arabidopsis and that engineering stress tolerance may not necessarily cause extensive changes to the transcriptome.
