A role for PICKLE in the regulation of cold stress response in Arabidopsis

Project description:Our study showed that the CHD3 protein PKL plays a role in the regulation of cold stress response likely via the regulation of chlorophyll accumulation under low temperature conditions. Our results suggest that PKL may regulate cold response partly via a CBF3-mediated pathway. Besides, our results reveal that the PKL gene is also involved in the regulation of drought and salt stress resistance.

A Role for PICKLE in the Regulation of Cold and Salt Stress Tolerance in Arabidopsis.

Project description:Arabidopsis PICKLE (PKL) is a putative CHD3-type chromatin remodeling factor with important roles in regulating plant growth and development as well as RNA-directed DNA methylation (RdDM). The role of PKL protein in plant abiotic stress response is still poorly understood. Here, we report that PKL is important for cold stress response in Arabidopsis. Loss-of-function mutations in the PKL gene lead to a chlorotic phenotype in seedlings under cold stress, which is caused by the alterations in the transcript levels of some chlorophyll metabolism-related genes. The pkl mutant also exhibits increased electrolyte leakage after freezing treatment. These results suggest that PKL is required for proper chilling and freezing tolerance in plants. Gene expression analysis shows that CBF3, encoding a key transcription factor involved in the regulation of cold-responsive genes, exhibits an altered transcript level in the pkl mutant under cold stress. Transcriptome data also show that PKL regulates the expression of a number of cold-responsive genes, including RD29A, COR15A, and COR15B, possibly through its effect on the expression of CBF3 gene. Mutation in PKL gene also results in decreased cotyledon greening rate and reduced primary root elongation under high salinity. Together, our results suggest that PKL regulates plant responses to cold and salt stress.

defenses mechanism in response to cold stress-PI4kinases and Long-chain bases kinases in response to cold stress

Project description:au10-10_froid - defenses mechanism in response to cold stress - Role of PI4 kinase and Long-chain bases kinases in response to cold stress - Plantlets of wild type and mutant were grown vitro for 14 days in a growth chamber (80% humidity, 80 micro Enstein without photoperiod). The 15th day, plantlets were transferred at 4°C or 12°C during 4 hours (80 micro Enstein) for the cold stress.

ADAPTATION AND RESPONSE OF KOBRESIA LITTLEDALEI TO COLD STRESS

Project description:This study presents an integrated transcriptome sequencing to identify how Kobresia littledalei plants mount their responses and initiate acclimation against cold stress. Several significant DEGs and metabolic responses were categorized. By execution of BLAST analysis of the all genes against selected protein databases like Nr, Swiss-Prot, KEGG and COG, we got functional annotations and classifications. The large number of transcriptomic sequences and their functional annotations provide sufficient resources for future molecular studies. Moreover, information on the KEGG metabolic pathways and transcription factors will facilitate the discovery of other cold resistant genes. Importantly, our findings herein further the general understanding of Kobresia plants adaptation and responses to cold stress through the molecular mechanisms involved in signal regulation and cold resistance.

Regulation of cold-induced thermogenesis by the stress granule protein FAM195A

Project description:Homeothermic vertebrates are capable of surviving in cold environments by maintaining constant body temperature through thermogenesis, in which brown adipose tissue (BAT) produces heat by increasing mitochondrial oxidation along with the uncoupling of the electron transport chain and activation of uncoupling protein 1 (UCP1). Although the transcription factors that control the expression of UCP1 and genes involved in nutrient oxidation, mitochondrial function, have been extensively studied, only a few other proteins essential for BAT function have been identified. Here we describe the discovery of FAM195A, a disordered domain RNA-binding protein associated with stress granules that is required for cold-dependent thermogenesis in mice. FAM195A expression is enriched in BAT and striated muscles, and mice lacking FAM195A display whitening of BAT and an inability to survive at cold temperatures. In BAT of mice lacking FAM195A, key enzymes involved in branched chain amino acid (BCAA) metabolism, in particular leucine, and fatty acid (FA) oxidation are downregulated, impairing the physiological response to cold stress. Moreover, in vitro knock down of FAM195A impairs expression of leucine oxidation enzymes, revealing a direct role of FAM195A in the regulation of BCAA metabolism during thermogenesis

Identification of microRNAs involved in cold stress response in grapevine.

Project description:Two small RNA libraries were generated from micropropagated â??Muscat Hamburgâ?? (Vitis vinifera) plantlets under normal and low temperatures (4 Â°C). A total of 163 known miRNAs and 299 putative novel miRNAs were detected from two small RNA libraries by Solexa sequencing. Forty-four cold-inducible miRNAs were identified through differentially expressed miRNAs (DEMs) analysis; among which, 13 belonged to upregulated DEMs while 31 belonged downregulated DEMs. This study indicated that a diverse set of miRNAs in V. vinifera are cold-inducible and may play an important role in cold stress response. Examination of small RNA populations in grapevine under cold treatment and none cold treatment.
