Transcription profiling of wild type and mutant Arabidopsis plants infected with Pythium irregulare

ABSTRACT: To characterize the plant molecular response to Pythium irregulare, whole genome transcriptional profiles of infected and non-infected, wild type, jasmonic acid insensitive (coi1-1), ABA biosynthesis mutants (aba2-12), ein2-5 mutant, sid2-1 plants were obtained using two-color long-oligonucleotide microarrays.

Analyses of Arabidopsis thaliana defense response to the damping-off oomycete pathogen Pythium irregulare show that resistance to P. irregulare requires a multicomponent defense strategy. Penetration represents a first layer, as indicated by the susceptibility of pen2 mutants, followed by recognition, likely mediated by ERECTA receptor-like kinases. Subsequent signaling of inducible defenses is predominantly mediated by jasmonic acid (JA), with insensitive coi1 mutants showing extreme susceptibi ...[more]

Transcription profiling of Arabidopsis roots with or without treatment with 9-hydroxyoctadecatrienoic acid

Project description:Gene expression of roots grown on MS medium versus MS+9HOT was compared. 6-day-old seedlings grown on MS were transferred to fresh plates and grown for 3- or 5- additional days in the absence or in the presence of 9-HOT (25 um). Root fragments grown after transferring to fresh plates were excised and used to compare gene expression between controls and 9-HOT treated seedlings.

Transcriptional profiles of yeast on acetate exposed to pure nitrogen or carbon monoxide

Project description:Oxygen lack of various severity can force many organisms to enter into recoverable hypometabolic states. To better understand how organisms cope with oxygen deprivation, our lab had previously shown that when challenged with anoxia, both the nematode Caenorhabditis elegans and embryos of the zebrafish Danio rerio enter into suspended animation, where all life processes that can be observed by light microscopy reversibly halt, pending restoration of oxygen. Here, we show that both sporulating and vegetative cells of the budding yeast Saccharomyces cerevisiae also enter into a similar state of suspended animation when made anoxic on a non-fermentable carbon source. Transcriptional profiling using cDNA microarrays shows upregulation of aerobic metabolism genes in carbon monoxide (CO)-induced anoxia, but not nitrogen (N2) gas-induced anoxia, consistent with the known oxygen-mimetic effects of CO. Our results lead us to propose a model for oxygen-regulated gene expression in yeast where two oxygen-sensitive mechanisms operate simultaneously, such that treatment with N2 results in both mechanisms signaling a lack of oxygen, while treatment with CO results in one sensing mechanism signaling a lack of oxygen, while the other signals an abundance of oxygen. Cells were pregrown on glucose media. Cells were then plated onto nylon membranes on acetate solid media and made anoxic using either pure nitrogen or carbon monoxide. Cells were collected at 15, 30, 45, 60, 120 minutes and 24 hours after initiation of gas exposure. Reference samples were derived from cells on acetate in room air for corresponding time point. Six CO-treated samples were compared to room air references and six nitrogen-treated samples were similarly compared to room air references.

Transcription profiling of Arabidopsis Ler/Cvi recombinant inbred line popultion to assess natural variation in gene expression

Project description:To assess natural variation in gene expression in Arabidopsis thaliana, genome wide gene expression variation was analyzed in a Ler/Cvi recombinant inbred line (RIL) population.The variation in expression could be explained for many genes by expression quantitative trait loci (eQTLs). These eQTLs are combined with regulator candidate gene selection to generate genetic regulatory networks.

OsMYB4-Regulated Transcriptional Network of Rice

Project description:The OsMyb4 transcription factor of rice represents a more recent example of a regulatory gene used in various attempts to develop stress-tolerant crops by regulon engineering. Although OsMyb4 confers tolerance to low temperature and drought by affecting the biosynthesis of compatible osmolytes and the phenylpropanoid metabolic process, the exact composition and scope of the OsMyb4 network has not been established from the previous analysis of heterologous overexpression in Arabidopsis. Further characterization of the OsMyb4 regulon at the global scale will facilitate understanding of the intricate underpinnings of a pathway independent of the DREB/CBF network. To dissect the OsMyb4 network of rice in relation to chilling stress response mechanisms, we conducted a gene expression profiling using transgenic rice overexpressing the OsMyb4 cDNA. This experiment describes the analysis of the gene expression changes as a result of supra-optimal expression of transcription factor (OsMYB4) overexpressed as transgenic in the cv. Nipponbare. Control (WT) and transgenic (OsMYB4-OX) samples were labeled with Cy3 and Cy5, respectively. No dye-swap replicates was performed in this experiment. The microarray platform used in this study was the 45k oligonucleotide microarray (www.ricearray.org), which comes in pairs of slides A and B (each containing about 50% of the total number of features). The data described in this series includes all hybridizations with slide A and with slide B. Experiments were performed with two independent biological replicates (R1 and R2) for each transgenic line.
