(Submitter supplied) Five SAGE libraries were generated from A. thaliana leaf tissue collected at time points ranging from 30 minutes to one week of low temperature treatment (4°C). Over 240,000 high quality SAGE tags, corresponding to 16,629 annotated genes, provided a comprehensive survey of changes in the transcriptome in response to low temperature, from perception of the stress to acquisition of freezing tolerance. more...

(Submitter supplied) Plant responses to abiotic stresses are accompanied by massive changes in transcriptome composition. To provide a comprehensive view of stress-induced changes in the Arabidopsis thaliana transcriptome, we have used whole-genome tiling arrays to analyze the effects of salt, osmotic, cold and heat stress as well as application of the hormone abscisic acid (ABA), an important mediator of stress responses.

(Submitter supplied) During low temperature exposure, temperate plant species increase their freezing tolerance in a process termed cold acclimation. During deacclimation in response to warm temperatures cold acclimated plants lose freezing tolerance and resume growth and development. While considerable effort has been directed toward understanding the molecular and metabolic basis of cold acclimation, much less information is available about the regulation of deacclimation. more...

(Submitter supplied) To understand the gene network that controls plant tolerance to cold stress, we carried out a near full genome transcript expression profiling in Arabidopsis using Affymetrix GeneChips that contain approximately 24,000 genes. For microarray analysis, Arabidopsis seedlings were cold treated at 0 C for 0 h, 3 h, 6 h, and 24 h. A total of 939 genes were statistically determined to be cold-regulated with 655 being up-regulated and 284 down-regulated. more...

(Submitter supplied) The two Arabidopsis ecotypes that are adapted to Italy and Sweden, respectively, showed different degree of freezing tolerance. By comparing the low temperature transcriptomes of the IT and SW ecotypes, we showed CBF pathway plays a significant role in natural variation of freezing tolerance.

(Submitter supplied) Gene expression Arabidopsis 24h cold-treated, 4c, seedlings to identify a *gold-standard* set of cold-responsive transcripts. Most of the CBF overexpression lines are in WS, therefore, it is necessary to identify a consistent set of transcripts that are detectible as cold-induced on the ATH1 platform for both WS and Columbia, so that appropriate comparisons can be made to determine the effects of low temperature in CBF overexpressing or loss of function plants in a WS background and an attempt can be made to compare the results of altered CBF function to published microarray studies. more...

(Submitter supplied) Our goal in this study is to understand the regulation mechanism of genes including CBF regulon in low temperature. We addressed these issues by overexpressing the transcription factors encoded by genes that are rapidly induced in parallel with the CBF genes. The results show that the low temperature regulatory network is highly interconneted.

(Submitter supplied) Biotic and abiotic stresses limit agricultural yields, and plants are often simultaneously exposed to multiple stresses. Combinations of stresses such as heat and drought or cold and high light intensity, have profound effects on crop performance and yeilds To analyze such responses, we initially compared transcriptome changes in ten Arabidopsis thaliana ecotypes using cold, heat, high light, salt and flagellin treatments as single stress factors or their double combinations.

(Submitter supplied) Essential metals such as iron are required for healthy plant growth. Fe is an important cofactor and catalytic element in many biological processes. Fe and other metals can also be toxic when present in excess. Therefore plants have mechanisms of metal homeostasis which involve coordination of metal ion transporters for uptake, translocation and compartmentalisation. The NAS genes are supposed to play an important role in Fe homeostasis. more...

(Submitter supplied) Plant defence against insects is well known to be affected by previous exposure to cues warning of herbivory. Using Arabidopsis thaliana and the herbivore Pieris brassicae, we addressed the question whether the maintenance of the effects of the warning cue depends on its reliability. We determined the transcriptomes of Arabidopsis leaves that were treated by P. brassicae egg deposition (i) five days after oviposition, (ii) one day after removal of the eggs following the egg treatment, (iii) three days after removal of the eggs, (iv) after two days of herbivory that started one day after removal of the eggs; or that were treated by chilling (v) five days after transfer to 4°C, (vi) one day after transfering the plants to 20°C following the chilling treatment, (vii) three days after transfering the plants to 20°C, (viii) after two days of herbivory that started one day after transfering the plants to 20°C.
