The Arabidopsis COP9 signalosome is essential for G2 phase progression and genomic stability.

Development (Cambridge, England) 20080423 11

The COP9 signalosome (CSN) is required for the full activity of cullin-RING E3 ubiquitin ligases (CRLs) in eukaryotes. CSN exerts its function on CRLs by removing the ubiquitin-related NEDD8 conjugate from the cullin subunit of CRLs. CSN seems, thereby, to control CRL disassembly or CRL subunit stability. In Arabidopsis thaliana, loss of CSN function leads to constitutive photomorphogenic (cop) seedling development and a post-germination growth arrest. The underlying molecular cause of this grow ...[more]

Transcription profiling of Arabidopsis thaliana early response to the phytohormone Gibberellin (GA)

Project description:The phytohormone GA controls multiple important developmental processes in plants such as germination, elongation growth and flowering time. In this experiment, we look for early GA response genes in 7 day-old light-grown Arabidopsis seedlings. To this end we compare four data sets: (1) a GA biosynthesis mutant ga-1 (SALK_109115) mock treated for 1 hr; (2) a GA biosynthesis mutant ga-1 (SALK_109115) treated for 1 hr with 100 ÂµM GA3; (3) a gid1a-1 gid1b-1 gid1c-2 GA receptor triple mutant mock treated for 1 hr; (4) a gid1a-1 gid1b-1 gid1c-2 GA receptor triple mutant treated for 1 hr with 100 ÂµM GA3. In a comparison of the two ga-1 samples, GA regulated genes can be identified, and the assumption is that bona fide GA regulated genes are not responding in the gid1a-1 gid1b-1 gid1c-2 GA receptor mutant.

Transcriptional profiling of the rust fungus Cronartium quercuum f. sp. fusiforme (Cqf) during vegetative growth on 2 different hosts.

Project description:The purpose of this study was to make a single comparison between Cqf genes expressed during the vegetative stages of infection on the telial host (oak leaf) versus the aecial host (pine stem). A large proportion of genes were expressed in both hosts and significantly differentially expressed genes were enriched for candidate fungal effectors (small secreted proteins). These results suggest that the Cqf rust fungus uses a largely common set of genes to create two very different infection phenotypes. This study was based on hybridizations to custom microarrays containing features representing 8692 gene models from a Cqf genome sequencing project midpoint assembly. Two Agilent 4 X 44K microarray slides were populated with 60-mer probes (1 to 5 per transcript), designed using AgilentM-bM-^@M-^Ys web-based eArray software. Labeled target cRNA (complementary RNA) was generated using AgilentM-bM-^@M-^Ys Low Input Quick Amp Labeling Kit, such that oak and pine samples were labeled with either cy3 or cy5 an equal number of times across the experiment. Each microarray was hybridized with labeled cRNA target derived from a single oak sample and labeled cRNA target derived from a single pine sample. There were a total of eight oak sample replications and eight pine sample replications. Target hybridization and scanning were performed by the University of FloridaM-bM-^@M-^Ys Interdisciplinary Center for Biotechnology Research using standard procedures and an Agilent G250B Scanner.

Transcription profiling of rat astrocytes treated with epidermal growth factor (EGF)

Project description:Primary cultures of astrocytes from rat optic nerve heads were treated with EGFR ligand, EGF. Two cell lines from two different rat donors were used. The sister cell cultures were set as control and EGF treated groups. Experiment Overall Design: experiment #1: compared control astrocyte cultures to sister cultures treated with EGF for 4 hours. Experiment Overall Design: experiment #2: compared control astrocyte cultures to sister cultures treated with EGF for 12 hours

Transcriptome of rice seedling and callus based on RNA-seq method

Project description:To support our research of epigenomics in rice genome, we conducted massively parallel pyrosequencing of mRNAs (RNA-seq) using rice seedling and callus tissues. We obtained a total of 40.1 M reads from seedling and 29.6 M reads from callus.The RNA-seq data derived from the replicates showed high correlations (Spearman’s rank correlation coefficient, SC, 0.96 for seedling, 0.88 for callus). Our RNAseq data derived from the seedling also showed a high correlation with the recently published rice RNA-seq data that was also from two-week old seeding tissue (Lu et al., 2010, PMID: 20627892) (SC=0.87). Two biological replicates of each tissue was applied in RNA-seq. Each biological replicate was sequenced twice in separate lane.

Transcription profiling of hy5 single mutant, hyh single mutant, hy5 hyh double mutant and wild type Arabidopsis seedlings of two different ecotypes and with or without auxin treatment

Project description:Arabidopsis thaliana seedlings comprising hy5 single mutant , hyh single mutant, hy5 hyh double mutant and wild-type plants were germinated in the dark on agar medium on usual Murashig and Skoog medium (pH 5.8) without sucrose. After 3 days of germination, etiolated seedlings were transfered to light conditions in liquid media similar to previous one but without agar . After 5 hours, auxin (10 micromolar IAA) was added to all treated samples except to controls (Mock treatment). all samples were harvested after one-hour treatment and frozen for further RNA extraction. Aim of the project was to detect impact of exogenous auxin treatment on each genotype
