The intracellular transfer of information (biological activation/inhibition) through a signal pathway. In each signal transduction system, an activation/inhibition signal from a biologically active molecule (hormone, neurotransmitter) is mediated via the coupling of a receptor/enzyme to a second messenger system or to an ion channel. Signal transduction plays an important role in activating cellular functions, cell differentiation, and cell proliferation. Examples of signal transduction systems are the GAMMA-AMINOBUTYRIC ACID-postsynaptic receptor-calcium ion channel system, the receptor-mediated T-cell activation pathway, and the receptor-mediated activation of phospholipases. Those coupled to membrane depolarization or intracellular release of calcium include the receptor-mediated activation of cytotoxic functions in granulocytes and the synaptic potentiation of protein kinase activation. Some signal transduction pathways may be part of larger signal transduction pathways; for example, protein kinase activation is part of the platelet activation signal pathway.

The majority of these functions deal with the degradation and modification of RNA. I am struggling to figure out how to differentiate between up-regulated and down-regulated genes based on geneontology website or the data given, but considering that the t15, t30, t60, t90 are up-regulated, while only t-120 is down-regulated, it would probably be reasonable to assume that these functions are mostly up-regulated. This would mean that due to cold-shock, cells primarily increase the breakdown of RNA,and mores specifically non-coding RNA, as suggested by the GO terms. This suggests that cold-shock induces translation in order to produce specific proteins involved in stress response ...

Osmoadaptation of four L. monocytogenes strains, possessing different tolerances to NaCl, revealed a clear pattern in terms of genomic expression. Prolonged exposure to high levels of NaCl was coupled with activation of genes associated with the bacterial cell envelope, DNA repair and protein synthesis. Repression of genes associated with carbohydrate up-take and metabolism was evident in osmo-adapted cells reflecting the overall suppression of cellular metabolism characterised by reduced growth rate of these cells. In addition the initial stage of osmo-adaptation, was examined in strain ATCC 19115 (serotype 4b) post short exposure to 10.0% (w/v) NaCl to investigate continuous spectrum of gene expression in response to osmotic stress in this organism. Gene enrichment analysis revealed a prominent, almost reverse gene expression profile in response to shock, compared to the adaptive response to the same concentration of NaCl. This study is the first to strongly highlight such distinction in gene ...

Benzyl alcohol and ethanol were found to exhibit an opposite effect on cold adaptation ofBacillus subtilis. The growth lag induced in bacteria by temperature shift-down was reduced in the presence of benzyl alcohol from 80 to 58 min, whereas ethanol prolonged this interval up to 102 min. In parallel, the physical state of the cytoplasmic membrane in intact bacteria was examined with the help of steady-state fluorescence anisotropy of diphenylhexatriene. Benzyl alcohol decreased the anisotropy as a consequence of membrane fluidization whereas ethanol increased its value, suggesting membrane rigidization. The correlation of growth and fluorescence data indicates that the control of membrane structure represents an important part of bacterial adaptation to cold.
Ambient particulate matters and temperature were reported to have additive effects over the respiratory disease hospital admissions and deaths. The purpose of this study is to discuss the interactive pulmonary toxicities of cold stress and fine particulate matter (PM2.5) exposure by estimating inflammation and oxidative stress responses. 48 Wistar male rats, matched by weight and age, were randomly assigned to six groups, which were treated with cold stress alone (0 degrees C, 10 degrees C, and 20 degrees C (Normal control)) and cold stresses plus PM2.5 exposures respectively. Cold stress alone groups were intratracheal instillation of 0.25 mL normal saline, while cold stress plus PM2.5 exposure groups were intratracheal instillation of 8 mg/0.25 mL PM2.5. These procedures were carried out for three times with an interval of 48 hours for each treatment. All rats were sacrificed after 48 hours of the third treatment. The bronchoalveolar lavage fluid (BALF) was collected for analyzing inflammatory ...
Plants experience a wide range of abiotic stresses due to their sessile nature. These stresses range from cold and draught to salinity and osmotic factors to which plants have evolved many biochemical responses. Significant research has revealed a complex network of genes that work together during stress conditions. A key player in the abiotic stress response in Arabidopsis is DREB1 (Dehydration Response Element Binding Protein) a family of three related (A, B, C) transcription factors that bind to DRE (Dehydration Response Element), a cis-acting element that functions in ABA-independent gene expression, specifically as an up regulator of rd29A. Researchers have demonstrated that rd29A is up regulated in response to salt, drought and cold conditions (Shinozaki, 1998).. Plant cold stress responses in Arabidopsis have been studied and shown to contain several pathways that are specific to abiotic stresses. The DREB1 family has been shown to be most strongly expressed in response to cold stress, ...

As a representative warm-season grass, Bermudagrass [Cynodon dactylon (L). Pers.] is widely used in turf systems. However, low temperature remarkably limits its growth and distribution. ABA is a crucial phytohormone that has been reported to regulate much important physiological and biochemical processes in plants under abiotic stress. Therefore, the objective of this study was to figure out the effects of ABA on the cold-sensitive (S) and cold-resistant (R) Bermudagrass genotypes response to cold stress. In this study, the plants were treated with 100 µM ABA solution and exposed to 4°C temperature. After 7 days of cold treatment, the electrolyte leakage (EL), malonaldehyde (MDA) and H2O2 content were significantly increased in both genotypes compared with control condition, and these values were higher in R genotype than those of S genotype, respectively. By contrast, exogenous ABA application decreased the electrolyte leakage (EL), malonaldehyde (MDA) and H2O2 content in both genotypes compared with
T. fasciatus (Takifugu fasciatus) faces the same problem as most warm water fish: the water temperature falls far below the optimal growth temperature in winter, causing a massive death of T. fasciatus and large economic losses. Understanding of the cold-tolerance mechanisms of this species is still limited. Integrated application of multi-omics research can provide a wealth of information to help us improve our understanding of low-temperature tolerance in fish. To gain a comprehensive and unbiased molecular understanding of cold-tolerance in T. fasciatus, we characterized mRNA-seq and metabolomics of T. fasciatus livers using Illumina HiSeq 2500 and UHPLC-Q-TOF MS. We identified 2544 up-regulated and 2622 down-regulated genes in the liver of T. fasciatus. A total of 40 differential metabolites were identified, including 9 down-regulated and 31 up-regulated metabolites. In combination with previous studies on proteomics, we have established an mRNA-protein-metabolite interaction network. There are 17
Plants experience a wide range of abiotic stresses due to their sessile nature. Plants have evolved many biochemical responses to stresses that range from cold and drought to salinity and osmotic factors. Substantial research has revealed a complex network of genes that work together during stress conditions. A key player in the abiotic stress response in Arabidopsis is DREB1 (Dehydration Response Element Binding Protein) a family of three related (A, B, C) transcription factors that bind to DRE (Dehydration Response Element), a cis-acting element that functions in ABA-independent gene expression, specifically as an up regulator of rd29A. Researchers have demonstrated that rd29A is up regulated in response to salt, drought and cold conditions (Shinozaki, 1998).. Plant cold stress responses in Arabidopsis have been shown to contain several pathways that are specific to abiotic stresses. The DREB1 family has been shown to be most strongly expressed in response to cold stress, salinity, osmotic, ...
Conclusions: Flies reared at constant benign temperatures were more fecund at all acclimationtemperatures. In contrast, flies reared under fluctuating natural or laboratory conditions weremore successful in locating food under cool conditions in the field, while constant cool rearingconditions led to high cold resistance. The fluctuating- and low-temperature rearing conditionsresulted in a similar metabolic profile, while the 24C rearing profile was distinct and showeda lack of plasticity. The effects of developmental acclimation on performance are thereforecomplex and cannot be captured through experimental comparisons of constant environments ...
The paliavana parent is P. tenuiflora, the best of the paliavanas. The hybrid does a better job of retaining its foliage than most paliavanas. The sinningia parent is S. conspicua, from which the hybrid acquires the generally white corolla color, the markings and yellow in the throat, and fragrance that can be detected at certain times. The plant has a tuber, an inheritance from its sinningia parent. Paliavana tenuiflora is much more vulnerable to cold than Sinningia conspicua. The hybrid seems to have the latters cold resistance. ...

URBANA, Ill. - Winters in eastern Russia are intensely cold, with air temperatures regularly reaching -30 degrees Fahrenheit in some locations. It is a seemingly inhospitable climate, but native plants have found ways to thrive there. University of Illinois plant geneticist Erik Sacks suspected one of these plants may hold the key to breeding cold-tolerant food and biomass crops. To find out, the modern-day botanical explorer set off across eastern Russia with colleagues from the N. I. Vavilov All-Russian Institute of Plant Genetic Resources (VIR) to collect specimens of the perennial grass Miscanthus sacchariflorus.. Miscanthus is part of a tribe of grasses, the Andropogoneae, that includes sorghum, sugarcane, and corn, Sacks explains. Because it is found so far north, this population of Miscanthus sacchariflorus is likely the most cold-hardy of that group. If we want to improve cold hardiness in this very important group of plants, this is going to be best population to study.. Sacks and ...

Among all cereals, rice is highly sensitive to cold stress, especially at the germination stage, which adversely impacts its germination ability, seed vigor, crop stand establishment, and, ultimately, grain yield. The dissection of novel quantitative trait loci (QTLs) or genes conferring a low-temperature germination (LTG) ability can significantly accelerate cold-tolerant rice breeding to ensure the wide application of rice cultivation through the direct seeding method. In this study, we identified 11 QTLs for LTG using 144 recombinant inbred lines (RILs) derived from a cross between a cold-tolerant variety, Lijiangxintuanheigu (LTH), and a cold-sensitive variety, Shennong265 (SN265). By resequencing two parents and RIL lines, a high-density bin map, including 2,828 bin markers, was constructed using 123,859 single-nucleotide polymorphisms (SNPs) between two parents. The total genetic distance corresponding to all 12 chromosome linkage maps was 2,840.12 cm. Adjacent markers were marked by an average
In this study, hematopoietic cells from mice pretreated with CVE and exposed to acute cold/restraint stress were stimulated in the presence of growth factors to form colonies, thus providing accurate information about the modulation of the green algae of the stress-induced changes in the hematopoietic response. Our results demonstrated that exposure to acute stress affected hematopoiesis. Mice exposed for a 2.5-hour time period of cold and restraint presented diminished clonal capacity for CFU-GM content per femur, which was decreased by as much as 50% compared with that in control mice, in spite of the significant increase in serum colony-stimulating activity (CSA). Treatment with 50 mg/kg CVE for 5 days, previously to the stress regimen, attenuates the effects of the stress, since comparable levels of myeloid progenitors were found in the bone marrow of both CVE/stress and control mice. Moreover, the sera from stressed mice pretreated with CVE further increased the CFU-GM formation. On the ...

Low temperature adversely affects crop yields by restraining plant growth and productivity. Most temperate plants have the potential to increase their freezing tolerance upon exposure to low but nonfreezing temperatures, a process known as cold acclimation. Various physiological, molecular, and metabolic changes occur during cold acclimation, which suggests that the plant cold stress response is a complex, vital phenomenon that involves more than one pathway. The C-Repeat Binding Factor (CBF) pathway is the most important and well-studied cold regulatory pathway that imparts freezing tolerance to plants. The regulation of freezing tolerance involves the action of phytochromes, which play an important role in light-mediated signalling to activate cold-induced gene expression through the CBF pathway. Under normal temperature conditions, CBF expression is regulated by the circadian clock through the action of a central oscillator and also day length (photoperiod). The phytochrome and phytochrome

MicroRNAs (miRNAs) are critical regulators responding to acute environmental stresses in both plants and animals. By modulating gene expression, miRNAs either restore or reconstitute a new expression program to enhance cell tolerance to stresses. Cold shock is one of the stresses that can induce acute physiological responses and transcriptional changes in aquatic creatures. Previous genomic studies have revealed many cold-affected genes in fish larvae and adults, however, the role of miRNAs in acute cold response is still ambiguous. To elucidate the regulatory roles of miRNAs in the cold-inducible responses, we performed small RNA-seq and RNA-seq analyses and found potential cold regulatory miRNAs and genes. We further investigated their interactions and involvements in cold tolerance. Small RNA-seq and RNA-seq identified 29 up-/26 down-regulated miRNAs and 908 up-/468 down-regulated genes, respectively, in responding to cold shock for 4 h at 18 °C. miRNA and transcriptomic analyses showed these miRNAs
Significant differences in responses to intraperitoneally injected tyramine or cold exposure (-10 degrees C) were observed in young (3-4 mo) male Sprague-Dawley (S-D) and Fischer 344 (F344) rats cold-acclimated (CA) or non-cold-acclimated (non-CA). Non-CA S-D and F344 rats respond to tyramine by increased O2 uptake and elevation of colonic temperature, but, as we had reported previously, the optimal doses of tyramine required was significantly different for these two strains, i.e., 2 mg/kg for F344 vs. 20 mg/kg for S-D. The response to tyramine was significantly potentiated by cold acclimation in both strains of rats. Despite the different dosages of tyramine given to the animals, similar increases in O2 uptakes and colonic temperatures were observed. Differences between these two strains were also evident in their responses to a cold challenge (3 h, -10 degrees C). The ranking for cold tolerance (-10 degrees C) was as follows: CA F344 greater than non-CA F344 greater than CA S-D greater than ...

Larvae and adults of A. aegypti are clearly capable of cold acclimation when presented with a change in larval or adult acclimation temperature. In the present study, we compared the effects of development or adult acclimation at only two temperatures (15 and 25°C), but demonstrate that this difference of 10°C was sufficient to substantially alter chill tolerance in this important vector of disease. Cold-acclimated larvae and adults more rapidly recovered from chill coma following cold stress, and had significantly higher survival following chronic cold. After 12-16 h at 2°C, very few larvae acclimated to 15°C showed any signs of chilling injury while ∼30% of larvae acclimated to 25°C were clearly suffering from neuromuscular injury that prevented them moving in a coordinated manner (Fig. 2B).. Chilling injury has been repeatedly associated with a systemic loss of ion balance in several terrestrial insects, including members of Hemiptera, Diptera, Blattodea, Lepidoptera and Orthoptera ...
Sorghum [Sorghum bicolor (L.) Moench] is the fifth most important cereal crop world-wide as well as an important source of feed, fiber and biofuel. It is a C4 plant and is well adapted to environments subject to high temperature and water limitation. Despite these agronomic qualities, it suffers from limitations of sensitivity to low temperature and the grain has drawbacks in relation to functionality and digestibility. The objectives of this study are: 1. To promote seed germination at low temperature and to enhance the seedling cold tolerance. 2. To enhance the grain digestibility and functionality. In an attempt to augment cold tolerance, we introduced the glycine rich RNA binding protein gene atRZ-1a from Arabidopsis, Bcl-2 mRNA sequence 725-1428 representing the 3 non coding region of the gene from humans and rice Ca-dependent protein kinase 7 (OsCDPK7), all of which are known to improve the cold tolerance of plants. None of these genes resulted in the improvement of cold tolerance in sorghum. On

David R. Foster1. Four great ice ages covered large parts of the upper northern hemisphere under solid ice as thick as one mile. The last glacier began to retreat from the future northeastern United States around 10,000 B.C.E., leaving a changed landscape with deeper valleys and huge inland seas. The residual glacial till, gravel, sand, and clay gradually broke down to create soil that allowed creeping, cold-tolerant plants to form a cover of tundra. The climate slowly warmed, and trees took root; a boreal forest of spruce and fir grew first. Pine and hemlock followed, joined later by hardwoods- maple, beech, and birch, then hickory, oak, and ash. This forest would continually change in response to climate, fire, new species, wind, disease, and human activity.. With the increasing vegetation, including nutritious plants that supported a variety of animals, predecessors of the Algonquin and Iroquois arrived. They lived here for thousands of years as hunter-gatherers, moving periodically to take ...

When I came back I tentatively mentioned it to Mike, perhaps expecting a sort of a cold response, but he didnt! He was immediately enthusiastic about the idea and we had to verify a few things. First we needed to make sure that he could apply for an unpaid leave of absence and get back to his job an salary (check!) and that I could on the other hand keep my salary or it would have been a serious problem (check!!). Mike was so on board that he even said maybe I can also do some work in some lab.. wow!! I immediately emailed the colleague in Davis and I mean, who wouldnt want a very experience, hands on post doc for free? He got back within minutes saying his colleagues would be fighting over him, no question! Apparently Davis is extremely family oriented and if Mike works then we have to look into childcare, but should not be a major issue. I would hope that my parents will spend maybe even a month there and could help. Renting somewhere should also be very very easy, Im assuming renting a ...

Early dormancy involves a number of phenomena: cessation of active growth, formation of terminal buds, formation of abscission layers in leaves, development of cold resistance, development of winter rest (a chilling requirement), and leaf fall. The buds of some tree species (or some races of a species) have a true rest or winter chilling requirement; usually the roots do not; perhaps the cambium does not. There is a wide range of genetic variation within and between species in response to photoperiod, winter chilling, water nutrients, and other environmental factors which affect the dormancy condition of plants.. During the period of winter rest there are many metabolic and developmental processes going on in the buds and twigs. These processes include respiration, photosynthesis, some cell division, enzyme synthesis, production of growth stimulators, and dissipation of growth inhibitors.. Dormancy of trees can be divided arbitrarily into three phases: early rest, winter rest, and after-rest. ...
