Chitin is a major component of fungal walls and insect exoskeletons. Plants produce chitinases upon pathogen attack and chito-oligomers induce defense responses in plants, though the exact mechanism behind this response is unknown. Using the ATH1 Affymetrix microarrays consisting of about 23,000 genes, we examined the response of Arabidopsis (Arabidopsis thaliana) seedlings to chito-octamers and hydrolyzed chitin after 30 min of treatment. The expression patterns elicited by the chito-octamer an ...[more]

The ThbZIP1 can be regulated by an ABF Transcription Factor and sensitivity to ABA treatment

Project description:In the current report, we report that ThbZIP1 is a direct target gene of the ThABF1 transcription factor. There are three ABRE motifs in the promoter of ThbZIP1, Yeast one-hybrid (Y1H) assays showed that a ABF protein, ThABF1, specifically binds to the ABRE motifs. The interaction between ThABF1 and the promoter of ThbZIP1 was further confirmed by transient expression assays in tobacco leaves. Chromatin Immunoprecipitation (ChIP) results suggested that binding of ThABF1 to ABRE motifs in the promoter of ThbZIP1 occurs in vivo in Tamarix hispida to regulate the expression of ThbZIP1. Moreover, ThABF1 and ThbZIP1 share similar expression patterns in response to salt, drought, ABA, methyl viologen (MV) and cold stress. Microarray analyses results showed there were 1,662 and 1,609 genes that were significantly upregulated or downregulated, respectively, under ABA stress conditions. ThbZIP1 regulated the genes via binding to the C-, G- or A-box motifs in their promoter sequences. Based on these data, the results suggested a regulatory network model mediated by ThbZIP1, under abiotic stress conditions, ThABF1 regulates the expression of ThbZIP1, and the activated ThbZIP1 binds to bZIP recognition sequences or other motifs to regulate the expression of genes containing these motifs in their promoters. Differentially expression genes of ThbZIP1-overexpression plants and wild type of Columbia Arabidopsis thaliana were measured under ABA stressed and normal condition for 3 hours, respectively. Two independent experiments were performed at each treatment using different plants for each experiment.

Arabidopsis AtbHLH112 protein positively regulates tolerance to abiotic stress and binds to the E-box and a novel motif GCG-box

Project description:Plant basic helix-loop-helix (bHLH) transcription factors are involved in physiological and developmental processes, and also play essential roles in abiotic stresses. However, their exact roles in abiotic stress are still need to be elucidated, and most of bHLHs have not been functionally characterized. In the present study, we characterized the functional role of AtbHLH112 in response to abiotic stresses. AtbHLH112 is a nuclear-localized protein, and its nuclear-localization is induced by salt, drought and ABA. Besides binding to E-box motif, AtbHLH112 is found to bind to a novel motif with the sequence M-bM-^@M-^\GG[GT]CC[GT][GA][TA]CM-bM-^@M-^] (GCG-box), and the binding affinity is induced by salt and ABA. Gain- and loss-of-function analyses showed that the transcript level of AtbHLH112 is positively correlated with salt and drought tolerance. AtbHLH112 mediates stress tolerance by upregulating the expression of P5CS genes and decreasing the expression of P5CDH and PRODH genes to increase proline levels, and via enhancing the expression of POD and SOD genes to improve ROS scavenging ability. All data together suggested that AtbHLH112 regulates the expression of genes through binding to GCG-box and E-box to mediate the physiological stress responses, including proline biosynthesis and ROS scavenging pathways to enhance stress tolerance. Differentially expression genes of AtbHLH112-overexpression plants, mutant (SALK_033618C) plants and wild type of Columbia Arabidopsis thaliana were measured under salt stressed and normal condition for 3 hours, respectively. Three independent experiments were performed at each treatment using different plants for each experiment.

PAB/WT polysome loading and transcript levels (Arabidopsis thaliana)

Project description:To understand the contribution of the poly(A)binding protein to the translation of specific mRNAs, we compared the ribosome occupancy of mRNAs in wild type Arabidopsis and pab2 pab8 double mutant seedlings. The mutants continue to express the PAB4 paralog of PABP. RNA was fractionated using sucrose gradients into polysomal and nonpolysomal RNAs. We also determined overall total transcript levels. We used Affymetrix ATH1 microarrays. Each plant sample was analyzed for the mRNA abundance in total mRNA (T), polysomal mRNA (PL), and nonpolysomal mRNA (NP). Four biological replicates were collected for polysomes and three for total RNA. The pab2 pab8 double mutant was compared with wild type.

Expression data from Arabidopsis thaliana root and piriformaspora indica during log and short term interaction

Project description:Piriformospora indica, an endophytic fungus of Sebacinales, colonizes the roots of many plant species including Arabidopsis thaliana. The symbiotic interaction promotes plant per-formance, growth and resistance/tolerance against abiotic and biotic stress. We demonstrate that exudated compounds from the fungus activate stress and defense responses in the Arabidopsis roots and shoots before the two partners are in physical contact. They induce stomata closure, stimulate reactive oxygen species (ROS) production, stress-related phytohormone accumulation and activate defense and stress genes in the roots and/or shoots. Once a physical contact is established, the stomata re-open, ROS and phytohormone levels decline, and the gene expression pattern indicates a shift from defense to mutualistic interaction. We propose that exudated compounds from P. indica induce stress and defense responses in the host. Root colonization results in the downregulation of defense responses and the activation of genes involved in promoting plant growth, metabolism and performance. Twelve day-old (48 h cold treatment and 10 days of illumination) Arabidopsis seedlings of equal sizes were selected for co-cultivation experiments. They were transferred to PNM plates with a nylone membrane on the top (Johnson et al. 2011) and exposed to a fungal plug 5 mm in diameter or a KM plug of the same size without fungal hyphae (control). The plugs were placed 3 cm away from the closest root part . The light intensity (80 Â± 5 Î¼mol m-2 sec-1) was checked every third day to ensure that both P. indica- and mock-treated seedlings receive equal amounts of light.

Transcription profiling of Arabidopsis sav mutants

Project description:Plants grown at high densities perceive a decrease in the red to far-red (R:FR) ratio of incoming light, resulting from absorption of red light by canopy leaves and reflection of far-red light from neighboring plants. These changes in light quality trigger a series of responses known collectively as the shade avoidance syndrome. During shade avoidance, stems elongate at the expense of leaf and storage organ expansion, there is reduced branching, and flowering is accelerated. We identified several loci in Arabidopsis, mutations in which lead to plants defective in multiple shade avoidance outputs. Here we describe SAV3, an aminotransferase, and show that SAV3 catalyzes the formation of indole-3-pyruvic acid (IPA) from L-tryptophan (L-Trp), the first step in a previously proposed, but uncharacterized, auxin biosynthetic pathway. This pathway can be rapidly deployed to biosynthesize auxin at the high levels required to initiate the multiple changes in body plan associated with shade avoidance. Experiment Overall Design: Wild type Col-0, sav3-2 and sav1-1 seedlings were used here. They were treated with or without 1hr of low R:FR light (R:FR ratio=0.7). Three independent biological replicates were used.

A polyadenylation factor subunit implicated in regulating oxidative stress responses in Arabidopsis thaliana

Project description:The oxt6 mutant is an oxidative stress-tolerant Arabidopsis mutant that is deficient in a polyadenylation factor subunit. Expression analysis suggests that impaired poly(A) site choice is responsible for the stress-tolerant phenotype. We used microarrays to understand the link between the polyadenylation defect and stress tolerance. Experiment Overall Design: Arabidopsis plants (the wild-type, oxt6 mutant, and two independent oxt6 transformants each carrying a gene encoding just the smaller of the two At1g30460-encoded proteins) were seeded and grown in soil. Plants were harvested for RNA isolation after 30 days; for this, six samples derived from 10-15 plants were prepared for each line. Ten samples were selected for study â three wild-type, three oxt6, and two from each of the complemented lines. Analysis of independent complemented plants minimizes the possible effects that may arise due to T-DNA insertion.
