(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) HRE1 and HRE2 are two ERF transcription factors induced by low oxygen. In this work we analyzed the effect of ectopic expression of HRE1 and HRE2 on the arabidopsis transcriptome in aerobic and hypoxic (1% O2) conditions. While HRE1 has a moderate effect on the expression of anaerobic genes under hypoxia, HRE2 does not affect them either under aerobic or hypoxic conditions.

(Submitter supplied) Leaf growth is a complex developmental process that is continuously fine-tuned by the environment. Various abiotic stresses, including mild drought stress, have been shown to inhibit leaf growth in Arabidopsis thaliana (Arabidopsis), but the underlying mechanisms remain largely unknown. Here we identify the redundant Arabidopsis transcription factors ETHYLENE RESPONSE FACTOR 5 (ERF5) and ERF6 as master regulators which adapt leaf growth to environmental changes. more...

(Submitter supplied) We characterized and compared the biological and molecular functions of HRE1α and HRE1β, two alternative splicing variants of HRE1, a AP2/ERF transcription factor in Arabidopsis. To compare the downstream regulatory mechanisms of HRE1α and HRE1β, Quant-Seq analysis was carried out. The experiment was designed to identify and compare differentially expressed genes (DEGs) between WT and HRE1α-overexpressing transgneic plants (OXs) and WT and HRE1β OXs grown for 14 days under SD conditions. more...

(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) Plants adapt to abiotic and biotic stresses by activating abscisic acid-mediated (ABA) abiotic stress-responsive and salicylic acid-(SA) or jasmonic acid-mediated (JA) biotic stress-responsive pathways, respectively. Although the abiotic stress-responsive pathway interacts antagonistically with the biotic stress-responsive pathways, the mechanisms that regulate these pathways remain largely unknown. more...

(Submitter supplied) To find genes directly regulated by ORA47, the P35S:ORA47-GR transgenic line was grown in the normal condition, treated with DEX and as well cycloheximide (CYC), prevented secondary transcriptional regulation downstream of ORA47 regulation by blocking protein synthesis. Gene expression patterns were then analyzed by microarray.

(Submitter supplied) To understand how plants respond to anoxia-reoxygenation, we have employed a global microarray expression profiling as a basic platform to characterize genes with the potential to mediate the recovery responses in Arabidopsis. 7-day-old seedlings were trated with 4hr and 8hr anoxia, and then reoxygenated in air for 0, 0.5, 1, 3, 6 hrs. Genes changed in both condition were designated as reoxygenation-regulated genes. more...

(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) T2 progenies of two transgenic lines overexpressing ERF transcription factor WIN1 were grown on soil in parallel under identical conditions. mRNA was extracted from pooled leaves from multiple plants of each line for the microarray experiement. Plants derived from two lines were used in this experiment: line 13, a "medium" overexpressor, and line 22, a strong overexpressor. Control mRNA was obtained from pooled control plants transformed using an empty binary vector. more...

(Submitter supplied) Our current study showed that the ABA and ethylene signal transduction pathways function in parallel and have antagonistic interaction during seed germination and early seedling growth. To further address the possible mechanism by which these two hormones crosstalk, microarray analysis was performed. By microarray analysis we found that an ACC oxidase (ACO) was significantly up-regulated in the aba2 mutant, whereas the 9-CIS-EPOXYCAROTENOID DIOXYGENASE (NCED3) gene in ein2, and both the ABSCISIC ACID INSENSITIVE1 (ABI1) and cytochrome P450, family 707, subfamily A, polypeptide 2 (CYP707A2) genes in etr1-1 were up- and down-regulated, respectively. more...

Despite this importance little is known on the molecular mechanisms regulating plant growth under water limiting conditions. The main goal of this work was to investigate, using a combination of growth and molecular profiling techniques, how stress arrests CELl proliferation in Arabidopsis thaliana leaves upon osmotic stress imposition.

(Submitter supplied) Arabidopsis mutants of the N-degron pathway have been shown to be either susceptible or resistant to a wide range of pathogens. This includes mutants for the arginine-transferases (ate1-2 ate2-1) and for the downstream E3 ubiquitin ligase PRT6 (prt6). In addition, ate1-2 ate2-1 mutants have been shown to have dampened gene expression changes upon inoculation with Pseudomonas syringae AvrRpm1. Here, we tested whether ate1-2 ate2-1 mutants were impaired for pattern-triggered immunity (PTI) and determined gene expression changes of wild-type Col-0 and of ate1-2 ate2-1 mutant seedlings in the absence/pressence of flg22.
