(Submitter supplied) This work is part of an existing collaboration between the two laboratories, funded by the EU (EU-RTN-INTEGA). Both parties will share the cost of this microarray experiment. Background: We have demonstrated that ethylene-insensitive mutants and wild type(col-0) Arabidopsis plants treated with an ethylene perception inhibitor have increased levels of expression of genes, such as GASA1 and g-TIP, that are thought to be regulated by GA (Vriezen et al, unpublished results). more...

(Submitter supplied) Transcription profiling of post-anthesis unfertilized pistil development and senescence in Arabidopsis, in a serie including samples from seven different stages according to pistil age in days post-anthesis (dpa). The time course started at anthesis and ended at 12-14 dpa, several days later of the loss of fruit set capacity. Keywords: Developmental time course

(Submitter supplied) Background: Polycyclic aromatic hydrocarbons (PAHs) are toxic, widely-distributed, environmentally persistent, and carcinogenic byproducts of carbon-based fuel combustion. Previously, plant studies have shown that PAHs induce oxidative stress, reduce growth, and cause leaf deformation as well as tissue necrosis. To understand the transcriptional changes that occur during these processes, we performed microarray experiments on Arabidopsis thaliana L. more...

(Submitter supplied) The aim of this study is to identify early DELLA protein-responsive genes using a Dexamethasone (DEX)-inducible system. Two transgenic lines were used: one induces the expression of a dominant, gibberellin non-responsive DELLA protein (rga-delta17); the other is a control line that carries the same vector, but lacks the rga-delta17 transgene. By comparing the gene expression changes in the line that expresses the rga-delta17 protein in the presence or absence of DEX it is possible to identify putative targets of DELLA proteins. more...

(Submitter supplied) The aim is to identify early gibberellin responsive genes in a gibberellin deficient strain such as ga1-3. Such genes are likely regulated by DELLA proteins which are master gibberellin repressors. DELLA proteins are rapidly degraded after gibberellin treatment, but their direct target genes still need to be elucidated. Keywords: hormone response, gibberellin treatment

(Submitter supplied) We have used Agilent whole genome arrays (v4) to compare the gene expression changes between 10-day-old Arabidopsis wild type seedlings and arf2-8 (Ellis et al., 2005), gnc gnl (Richter et al., 2011) and arf2 gnc gnl mutants (all Col ecotype).

(Submitter supplied) Arabidopsis brm plants depleted in a SWI/SNF-type ATPase BRM have decreased level of endogenous gibberellins and a phenotype that in many respects resembles the phenotype of mutants with repressed GA signaling or biosynthesis, like ga1-3. ga1-3/brm double mutant showed several additive and synergistic effects. To examine whether the phenotypic traits of brm, ga1-3 and ga1-3/brm lines are reflected at the gene expression level, we compared the expression profiles of brm, ga1-3, ga1-3/brm and wild-type plants using microarray analysis. more...

(Submitter supplied) Phytohormones play crucial roles in regulating many aspects of plant development. Although much has been learned about the effects of individual hormones, cross-talk between and integration of different hormonal signals are still not well understood. We present a study of MINI ZINC FINGER 1 (MIF1), a putative zinc finger protein from Arabidopsis, and suggest that it may be involved in integrating signals from multiple hormones. more...

(Submitter supplied) To mimic natural flooding conditions, we have adopted an “open system” treatment, in which only roots are subjected to hypoxia treatment. Using microarray analysis, we identified a number of AP2/ERF genes in Arabidopsis that are induced at different stages of hypoxia treatment. we performed microarray analysis to compare gene expression profiles of wild-type and AtERF73/HRE1-RNAi20 upon normaxic or hypoxic condition, in which AtERF73/HRE1 expression was severely knocked down.

(Submitter supplied) Ethylene-dependent gene expression was assayed by treating with 1 uM ACC, an ethylene precursor, or a control treatment to Arabidopsis seedlings by transferring 6 day old Arabidopsis grown on a a nylon mesh to fresh ACC-containing or control media Seedling roots were harvested 0, .5, 1, 2, 4, 8, 12, and 24 hours after treatment and the resultant RNA was used for microarray analysis to determine the kinetic profiles of auxin-responsive gene expression

(Submitter supplied) Loss of Lon1 led to stunted plant growth and accumulation of nuclear‐encoded mitochondrial proteins including Lon1 substrates. However, an in‐depth label‐free proteomics quantification of mitochondrial proteins in lon1 revealed that the majority of mitochondrial‐encoded proteins decreased in abundance. Additionally, we found that lon1 mutants contained protein aggregates in the mitochondrial that were enriched in metabolic enzymes, ribosomal subunits and PPR‐containing proteins of the translation apparatus. more...
