(Submitter supplied) Transcriptome analysis of RNA samples from WT and antisense-acetyl-CoA (ACLA) mutant. The antisense-ACLA mutant and WT plants were arranged according to a Randomized Complete Block Design. The plants were planted in rows with seven rows in each flat; two plants of the same genotype/pot. Plants were grown under a SD photoperiod (8 h light/16 h dark) in a growth chamber as described. Eight randomly selected rows were harvested for each time point from different flats. more...

(Submitter supplied) Pathogens infection exerts major effects on gene expression, which is reconfigured to raise the defences of the attacked plant. In the recent years the establishment of an hypoxic environment during Botrytis infection was described. We used the pentuple erfVII mutant to evaluate the contribution of ERFVII members to plant reaction to Botrytis and their effect on gene expression.

(Submitter supplied) Large-scale identification of transcripts with large cross-genotype differences in abundance provides a genome-wide approach to identify natural variation in gene function. Transcript profiling was performed in 20 Arabidopsis accessions at dusk, dawn and after a 6h extension of the night. Individual genes with a high variance in transcript abundances across accessions were identified by inspection at each individual time point and by ANOVA across all three time points. more...

(Submitter supplied) To comprehensively investigate the effects of glutathione on the gene expression, the microarray analysis was performed in the glutathione-fed wild-type Arabidopsis thaliana. Wild-type Arabidopsis (ecotype Columbia-0) were fed with 1 mM oxidized glutathione (GSSG) and 2 mM reduced glutathione (GSH) for comparison at equal nitrogen equivalents. To examine the effects of glutathione other than nitrogen at equal nitrogen equivalents, plants were fed with 3 mM NH4NO3. more...

(Submitter supplied) Transciptome profileing analysis of wt, nlp6, nlp7 and nlp6nlp7 before nitrate treatment and after 35 minutes of 25mM nitrate induction. NLP7 (NIN-LIKE-PROTEIN 7) (NLP7) is the major transcriptional factor responsible for the primary nitrate response (PNR), but the role of its closest homologue , NLP6, in nitrogen signaling and the interplay between NLP6 and NLP7 remain to be elucidated. In this study, we show that, like NLP7, nuclear localization of NLP6 via a nuclear retention mechanism is nitrate-dependent, but nucleocytosolic shuttling of both NLP6 and NLP7 is independent of each other. more...

(Submitter supplied) Plants need to be able to respond to changes quickly due to the inability of a plant to change location. Hormones within the plant signal for these transcriptional changes that will affect the plant's ability to survive. Strigolactone is a plant hormone that was more recently discovered so has a less detailed understanding of what genes it regulates, compared to other plant hormones. First published in Brewer et al 2016, PNAS We used microarrays to determine transcriptional responses in strigolactone mutants and in wild-type plants with various physiological treatment which affect hormone levels over 24 hours.

(Submitter supplied) AS2 encode AS2-domain containing protein and may regulate transcription. AS2 is involved in the determination of axes of leaves of Arabidopsis thaliana. Type IB DNA topoisomerase (TOP1α) gene has genetic interaction with AS1 and AS2 and is involved in repression of leaf polarity genes. To know the gene regulation in the leaf development, expression profile among wild-type and as2 mutant treated with and without 10-hydroxyl substituted camptothecin (10H-CPT), a specific TOP1 inhibitor, were compared

(Submitter supplied) The red-light regulated transcription factors FHY3 and FAR1 form a key point of light input to the plant circadian clock in positively regulating expression of genes within the central clock. However, the fhy3 mutant shows an additional red light-specific disruption of rhythmicity which is inconsistent with this role. Here we demonstrate that only fhy3 and not far1 mutants show this red specific disruption of rhythmicity. more...

(Submitter supplied) Brassinosteroids (BRs) are steroid hormones involved in multiple processes of plant growth and development, and the adaptation to the environment. Some of the processes regulated by BRs are meristem activity and stem cell divisions. At the core of the root stem cell niche, it is placed the quiescent center (QC), that act as a cell reservoir. QC cells only trigger their divisions when need to replenish the stem cells, for example, after a DNA damage. more...

(Submitter supplied) Spaceflight has an impact on growth and development of higher plants at both vegetative stage and reproductive stage. A great deal of information has been available on the vegetative stage in space, but relatively little is known about the influence of spaceflight on plants at the reproductive stage. In this study, we constructed a transgenic Arabidopsis thaliana plants expressing flowering control gene, FLOWERING LOCUS T (FT), together with green fluorescent protein gene(GFP) under control of a heat shock-inducible promoter (HSP17.4), by which we induced FT expression inflight through remote controlling heating shock (HS) treatment. more...

(Submitter supplied) The synthetic auxin 2,4-dichlorophenoxyacetic acid (2,4-D) functions as an agronomic weed control herbicide. High concentrations of 2,4-D induce plant growth defects, particularly leaf epinasty and stem curvature. Although the 2,4-D phenotype is associated with ROS production, little is known about ROS-dependent signalling. In this study, by using T-DNA Arabidopsis mutants to silence peroxisomal acyl CoA oxidase 1 (acx1-2), we identified ACX1 as one of the main sources of ROS production and as partly the cause of the epinasty phenotype following the application of 2,4-D. more...

(Submitter supplied) Autophagy involves massive degradation of intracellular components and functions as a conserved system that helps cells to adapt to adverse conditions. In Arabidopsis thaliana, submergence induces the transcription of autophagy-related (ATG) genes and the formation of autophagosomes. To study the role of autophagy during submergence, we performed transcriptome analysis with atg5, an autophagy-defective mutant, under submergence conditions. more...
