The impact of cold priming on the alerting phase of light and cold regulation of gene expression in Arabidopsis thaliana

ABSTRACT: We analysed the effect of a short 24 hours cold exposure (priming-stimulus) on gene regulation upon the first two hours of a second cold (4°C) stimulus (cold-triggering) and upon the first two hours of excess light exposure (800 µmol photons m-2 s-1, light triggering). The first and the second stress treatment was seperated by 5 days long lag-phase, which is long enough to reset most of the primary stress response. Several early light and early cold responsive genes showed however a altered transcript abundance in plants, which received five days befor the cold priming stimulus. Espicially JA responsive genes showed a common priming regulation within the cold and light exposure.

The impact of cold priming on the light and cold regulation of gene expression in Arabidopsis thaliana

Project description:We analysed the effect of cold priming on cold and high light regulation of gene expression. 5 days after the first cold treatment the primary stress response was widely reset. Then, a second (triggering) cold stimulus (24 h 4 °C) and a triggering high-light stimulus (2 h 800 µmol quanta m-2 s-1), which regulate many stress responsive genes in the same direction in naïve plants, caused widely specific and even inverse regulation of priming-responsive genes.

Specific CBF transcription factors and cold‐responsive genes fine‐tune the early triggering response after acquisition of cold priming and memory

Project description:Plants need to adapt to fluctuating temperatures throughout their lifetime. Previous research has shown that A. thaliana retains memory of a first cold stress (priming) and improves its primed freezing tolerance even further when subjected to a second similar stress after a lag phase. This study investigates primary metabolomic (gas chromatography–mass spectrometry) and transcriptomic (RNA-Seq) changes during 24 h of cold priming or cold triggering at 4°C. During triggering higher expression of genes encoding Late Embryogenesis Abundant (LEA), antifreeze proteins or proteins function as detoxifiers of reactive oxygen species (ROS) was observed compared to cold priming. Examples of early responders to triggering were xyloglucan endotransglucosylase/hydrolase genes encoding proteins involved in cell wall remodeling while late responders were identified to act in fine-tuning of stress response and development regulation. Four transcription factors, CBF2/DREB1C, CBF4/DREB1D, DDF2/DREB1E and DDF1/DREB1F were strongly and uniquely significantly induced throughout the entire triggering response. The induction of unusual members of the DREB subfamily of ERF/AP2 transcription factors, the relatively small number of induced genes of the CBF regulon and slower accumulation of selected cold stress associated metabolites proposes that a cold triggering stimulus might be sensed as milder stress in plants compared to priming. Further, the strong induction of CBF4 throughout triggering suggests a unique function of this gene during cold stress memory.

Cold priming and triggering of Arabidopsis accessions

Project description:Plants from temperate regions can be primed by exposure to low, non-freezing temperatures resulting in improved freezing tolerance. Whereas the molecular and metabolic basis of cold priming has been investigated in detail, hardly anything is known about memory of a previous cold event under warm conditions and a following low temperature triggering event. We show that three days of cold priming at 4°C, a seven-day lag phase at 20°C and a triggering treatment of 4°C improved the freezing tolerance of Arabidopsis Col-0 and other accessions compared to plants that were not primed before. Transcripts, metabolites and lipids as possible molecular determinants of this increase in freezing tolerance were investigated in Arabidopsis accessions Col-0 and N14 after priming, memory phase and triggering by Illumina-based RNA-Seq, GC-MS metabolite profiling and UPLC FT-MS-based lipidomics. Comparing primed and triggered with only triggered samples 93 and 128 unique differentially expressed genes could be identified in Col-0 and N14, together with three and six significantly changed lipids and one metabolite in N14. Possible functions of these candidates will be discussed. This work identified for the first time molecular and metabolic changes accompanying cold stress memory and triggering by a second cold stress.

Cold induced changes: differences between the Arabidopsis thaliana wild type and freezing sensitive mutants.

Project description:Arabidopsis sfr mutants are deficient in cold acclimation during exposure to coolnon-freezing temperatures. Although not visibly affected by the cold they have lost the ability to survive subsequent freezing. We plan to investigate how the sfr2 and sfr6 mutants respond to low temperature on the gene expression level. Wild type plants that have undergone identical treatments in parallel are necessary controls. The cold treatment of plants in the rosette stage (soil grown in a 8/16 hours day/night cycle) will be carried out in a cooled growth chamber at 4 degrees for 24 hours (same light regimetreatment starting/ending at the 4th hour of light). The aerial parts of the treated and untreated plants will be collected and frozen immediately in liquid nitrogen for RNA extraction. Comparison of the cold response of thousands of Arabidopsis genes in the wild type to the situation in our freezing sensitive mutants will enhance our understanding of the cold response itself and illuminate the effect of the mutations on the cold acclimation process.

Cold acclimation

Project description:Experiment was designed to identify transcriptome changes during cold acclimation of Drosophila melanogaster male flies. Resistance to cold is often measured by recovery times from chill coma, which is induced almost immediately upon exposure to low but non-freezing temperatures (~0C), with flies becoming immobilised and losing motor activity. This paralysis is also ostensibly reversible upon return to normal temperatures, although again there can be longer term effects. Acclimation for increased cold resistance requires exposure periods ranging from hours or days to several weeks at low temperatures between 0C to 12C, and samples were taken during the cold acclimation period (1 hr, 2 hr, 3 hr, 6 hr, 12 hr, 24 hr, 36 hr and 48 hr).

Expression data in Arabidopsis Col-0 with cold acclimation (CA) treatment and subsequent cold deacclimation (DA) treatment.

Project description:To understand mRNA expression pattern during cold acclimation and deacclimation, transcriptional profiling of cold acclimation and deacclimation-treated plants were analyzed using Agilent-015059 Arabidopsis 3 Oligo Microarray 4x44K G2519F. Arabidopsis Col-0 were grown on MS plate for 2 weeks (16 hours light / 8 hours dark). Two week-old Arabidopsis samples (NA, non acclimation) were treated with cold (2 M-BM-:C) for 7 days (CA7d) under 12h/12h light/dark conditions. Deacclimation-treated samples (DA6h, DA12h, DA24h) were grown at normal growth temperature under long day conditions after cold treatment for 7 days. Then total RNA was prepared from the whole seedling and used for the microarray hybridization. Three replicative hybridization experiments for each array were carried out using the independent biological samples.

Janus-faced nature of light in the cold acclimation processes of maize

Project description:Earlier findings indicated that light plays a critical role in the development of frost tolerance in winter cereals. However, the exact mechanism is still poorly understood. In the present work the effects of light during the cold acclimation period were studied in chilling-sensitive maize plants. The results show that although exposure to relatively high light intensities during cold acclimation at 15 °C causes various stress symptoms, it enhances the effectiveness of acclimation to chilling conditions (5 °C in the light). Interestingly, certain stress responses were light-dependent not only in the leaves, but also in the roots. A microarray study was also conducted to achieve a better understanding of the interaction of low temperature and light intensity during the cold hardening period. Numerous genes significantly differentially expressed were observed in almost all assimilation and metabolic pathways. Acclimation at moderately low temperature and low light intensity reduced the level of soluble sugars, while chilling increased it. Greater accumulation during hardening was detected at relatively high light intensity. It seems that the photoinhibition induced by low temperature is a necessary evil for cold acclimation processes in plants.
