Transcription profiling of nine ecotypes of Arabidopsis before and after 14d of cold acclimation at 4 degrees C

ABSTRACT: Nine accessions of Arabidopsis were sampled before and after 14d of cold acclimation at 4°C. Transcript data were combined with metabolite data and related to quantitative measurement of plant freezing tolerance as determined by leaf electrolyte leakage assays.

Natural genetic variation of freezing tolerance in Arabidopsis.

Low temperature is a primary determinant of plant growth and survival. Using accessions of Arabidopsis (Arabidopsis thaliana) originating from Scandinavia to the Cape Verde Islands, we show that freezing tolerance of natural accessions correlates with habitat winter temperatures, identifying low temperature as an important selective pressure for Arabidopsis. Combined metabolite and transcript profiling show that during cold exposure, global changes of transcripts, but not of metabolites, correla ...[more]

Transcription profiling of Arabidopsis thaliana rosettes IN an extended night

Project description:Usually starch is nearly depleted at the end of the night. To induce a gradual depletion of carbon, we have analysed the global response of transcripts during an extension of the night, where carbon becomes severely limiting from about four hours onwards. Experiment Overall Design: Arabidopsis thaliana rosettes were harvested in successive timpoints in an extended night situation.

Transcription profiling of Arabidopsis FNR1 mutants from different ecotypes

Project description:The mechanism by which plants regulate channeling of photosynthetically derived electrons into different areas of chloroplast metabolism remains obscure. In higher plants, these electrons are made accessible to stromal enzymes, or cyclic electron flow, as reduced ferredoxin (Fd), or NADPH. We investigated how the specific loss of an Arabidopsis (Arabidopsis thaliana) ferredoxin:NADPH reductase (FNR) isoprotein affected channeling of photosynthetic electrons into NADPH and Fd dependent metabolism. Affymetrix gene chip comparison of transcript changes in these mutants against two different ecotype backgrounds indicates that stress signaling is perturbed, and experiments revealed that the mutants are more susceptible to oxidative stress. Experiment Overall Design: We isolated arabidopsis mutants of the FNR1 gene in different ecotypes, extracted RNA from these and respective wild type plants and hybridised it to Affymetrix microarrays

Transcription profiling of Fusarium head blight resistance in Sumai-3 and two susceptible NILs

Project description:Microarray gene expression analysis were performed to identify genes responding to Fusarium graminearum inoculation and genes that show a differential regulation between the resistant c.v. Sumai-3 and the susceptible near isogenic lines. Sumai-3 is a Chinese wheat cultivar, the most commonly used source of resistance to Fusarium head blight (FHB) disease. NIL-3 and NIL-4 are near isogenic lines susceptible to FHB and are derived from a cross between Sumai-3 and Chuan980, a susceptible wheat cultivar, followed by seven generations of marker assisted backcrossing with the recurrent parent Sumai-3 and selection for FHB susceptibility in each generation by artificial inoculation with F. graminearum. A combination of DNA markers including simple sequence repeats (SSRs) and amplified fragment length polymorphisms (AFLPs) were used to screen for DNA polymorphisms between Sumai-3 and its susceptible NILs. Polymorphic markers were mapped using a mapping population. The analysis indicated 7 polymorphisms between the susceptible NILs and the resistant Sumai-3. The analysis indicated that NIL-3 differs from Sumai-3 at chromosome 3BS and NIL-4 differs from Sumai-3 at chromosome 2AL region.

Transcription profiling of wild type and RAP2.2 over-expressing Arabidopsis leaves

Project description:Comparison of rosette leaves of two different RAP2.2 overexpressing lines with wild type leaves. The AP2/EREBP transcription factor RAP2.2 was shown to bind to a cis-acting motif within the phytoene synthase promoter from Arabidopsis. To investigate effects of increased RAP2.2 levels, two RAP2.2 overexpressing Arabidopsis thaliana (ecotype Wassilewskija) lines were generated: one line, nosr2, carried the nos promoter and showed a two-fold increase in RAP2.2 transcript level, the second line, cmr-5, carried four copies of the CaMV-35S enhancer and showed a 12-fold increase. However, neither weak nor strong increase in RAP2.2 transcript amounts had any effect on RAP2.2 protein levels as shown by Western blot analysis. The strong robustness of RAP2.2 protein levels towards transcriptional changes can be explained by specific protein degradation which includes SINAT2, an E3 ubiquitin ligase which was isolated using a two-hybrid approach. Accordingly, global gene expression analysis using both RAP2.2 overexpressing lines showed only minor transcriptional changes which are probably due to minor growth variation than to mechanisms involved in the down-regulation of RAP2.2 protein amounts.

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.

Transcription profiling of barley exposed to low temperature stress

Project description:In this study we used the Affymetrix Barley 1 GeneChip to investigate transcriptome responses of barley cv. Morex to low temperature, including triplicated measurements of cold, freeze/thaw cycles and de-acclimation over 33 days. Experiment Overall Design: Plants were grown at 20ÂºC for seven days and subject to a symmetrical cycle of acclimation, cold, freeze-thaw, and deacclimation. Chilling began by decreasing the temperature overnight from 20ÂºC to 4ÂºC at a rate of 1.3ÂºCâ¢h-1 and maintaining temperatures of 4 ÂºC in the day and 2ÂºC at night for 5 days. Freeze-thaw cycling lasted 12 days with day temperatures of 4ÂºC and night temperatures gradually decreasing from -2ÂºC the first night to -4ÂºC for three nights and -10ÂºC for four nights, then recovering to -4ÂºC for three nights and -2ÂºC for one night. This treatment was designed to allow daily freeze-thaw cycling and protein synthesis. Chilling conditions (4ÂºC day, 2ÂºC night) were resumed for five days, followed by deacclimation with increasing temperature to 20ÂºC overnight and maintaining for three days. Sampling was done at four different times, each at the 11th hour of light to avoid circadian effects: 1) before chilling treatment, 2) five days after initiation of chilling treatment, 3) eight days into freeze-thaw treatment and 4) three days into de-acclimation.

Transcription profiling of wheat cultivars after cold treatment

Project description:Different wheat cultivars may be classified as either winter or spring varieties depending on whether they require exposure to an extended period of cold in order to become competent to flower. Using a growth regime that mimics the conditions that occur during a typical winter in Britain, we wished to survey the genes that are involved in phase transition as well as those involved in cold-acclimation. Experiment Overall Design: We wished to study the profiles of expression of genes involved in both phase transition (vegetative to reproductive growth transition) and cold-acclimation. To that end we we exposed plants to a gradual, stepped decline in both temperature and light. We sampled plants at three time points (3 weeks post-germination, 5 weeks post germination and 9 weeks post germination). We took samples from two separate tissues (crown and leaf) to se whether responses were different. We used two biological reps for each time point and tissue. Control plants were exposed to a delined in day-length and light intensity, but not in temperature.
