Summary: Chemical compounds that affect intracellular processes have been identified in germinated seedlings, but using mature plants for chemical screening would advance our understanding of environmental responses. This study developed a high-throughput screening method using single leaves of mature plants to identify small molecules that affect cold-regulated gene expression. Derivatives of 1,4-naphthoquinone were found to specifically inhibit COR gene expression and upstream signaling processes in response to low temperature.

Summary: Kandelia obovata, the most cold-tolerant mangrove species, showed acclimation to cold waves through physiological changes and gene expression. We identified 1,135 cold acclimation-related genes (CARGs), which are involved in calcium signaling, cell wall modification, and ubiquitination pathways. CBFs and CBF-independent transcription factors played important roles in regulating the expression of CARGs.

Summary: This study reveals that CBF/DREB1 can regulate the accumulation of galactinol in Petunia hybrida through PhDREB1F and PhDREB1I, which enhances the plant's tolerance to cold stress. It is also found that PhDREB1F/1I can activate the expression of PhZFP1 and PhGolS1-1, leading to the accumulation of galactinol. These findings provide new insights into the molecular mechanism of plant responsiveness to cold stress mediated by CBF/DREB1 transcription factors.

Summary: Cold acclimation in Arabidopsis thaliana triggers significant transcriptional reprogramming through the CBF-dependent pathway, involving CBF transcription factors binding to conserved sequences on target genes. CBF-target genes are enriched in functions related to hormones, light, and circadian rhythm signaling, indicating their role as key integrators of endogenous and external cues.

Summary: This study reveals the genetic basis for cold adaptation in rice and identifies functional polymorphisms in the OsSEH1 gene between japonica and indica subspecies that may contribute to cold adaptation in japonica rice. The study also shows that OsSEH1 regulates the expression of genes involved in dehydration response and induces the expression of cold-regulated genes to enhance cold tolerance.

Summary: This study unravels the mechanism of cold tolerance in maize, showing that the transcription factor ZmICE1 plays a significant role in reprogramming amino acid metabolism and regulating the expression of specific genes involved in cold stress response, thus affecting cold tolerance in maize.

Summary: Warming in the Antarctic Peninsula is rapidly increasing and expected to become more imbalanced. It has already affected the growth and reproduction of Antarctic plants, leading to decreased freezing tolerance. Limited evidence exists about the effects of diurnal and nocturnal warming on freezing tolerance-related gene expression in D. antarctica.

Summary: This study elucidates the early molecular response and regulatory mechanism of cold-sensitive crops (e.g. tomato) to low temperature. The findings reveal that the oscillation of a large set of diurnally regulated genes is severely compressed within 30 minutes of chilling in both the shoots and roots, and this compression persists throughout the cold treatment but is relieved within 3 hours of returning to ambient temperatures. Additionally, the canonical ICE1/CAMTA-to-CBF cold response pathway is active in the shoots but not in the roots. Chilling stress induces synthesis of known cryoprotectants and the expression of genes encoding proteins involved in photosystems I and II, independently of the CBF pathway.

Summary: The study reveals that CBF1 expression is positively associated with cold tolerance in Citrus cultivars, while CBF2 or CBF3 genes did not show a clear relationship with susceptibility to CI. Light avoidance during fruit growth reduces postharvest CI in most sensitive cultivars, which may be linked to the rapid and transient enhancement in the expression of the three CBFs. This indicates that CBFs-dependent pathways mediate cold tolerance responses in sensitive Citrus, with CBF1 playing a role in natural tolerance to CI.

Summary: Through studying the DAM genes in the V. vinifera genome, it was found that these genes play an important role in regulating bud dormancy in grapevines, with the difference from other deciduous fruit trees being that they are regulated by the FT gene.

Summary: In this study, we identified 35 conserved cold-responsive transcription factor orthogroups (CoCoFos) through orthogroup analysis of five representative eudicots. Experimental validation showed that one of these transcription factors, BBX29, is a negative regulator of cold tolerance in Arabidopsis.

Summary: In this study, cold-acclimated and non-acclimated Camelina biotypes were compared for stress-associated biomarkers and gene expression. The results showed that cold acclimation had a positive effect on freezing tolerance, increasing the protein and proline content in stressed plants. Freezing stress significantly affected antioxidant enzyme activity and gene expression.

Summary: Environmental variation is a crucial problem that negatively affects food availability and leads to food insecurity. Wheat, being the largest staple food crop, is severely threatened by abiotic stresses such as salinity, heavy metal toxicity, drought, extreme temperatures, and oxidative stresses. Cold stress is a significant ecological constraint that hampers the development and yield of plants. Understanding cold tolerance and improving it in wheat is critical for expanding the adaptability of perennial grasses.
