Summary: The study revealed significant differences in cold hardiness and chilling fulfillment among four cold climate grapevine cultivars. Marquette showed the highest freezing tolerance, making it a potential sentinel cultivar for comparisons of new selections, while Brianna acclimated slower and deacclimated more rapidly than the other cultivars.

Summary: The study reveals that the Ca2+-permeable transporter ANNEXIN1 (AtANN1) mediates cold-triggered Ca2+ influx and freezing tolerance in Arabidopsis thaliana. The OST1/SnRK2.6 kinase interacts with and phosphorylates AtANN1, enhancing its Ca2+ transport activity and potentiating Ca2+ signaling in response to cold stress. This cascade linking OST1-AtANN1 leads to cold-induced Ca2+ signal generation, activating the cold response and enhancing freezing tolerance in Arabidopsis.

Summary: In apple, a key component of BR signaling, MdBIM1, increases cold tolerance by activating the expression of CBF genes and forming complexes with MdCBF2. The repressors of JA signaling, MdJAZ1 and MdJAZ2, interact with MdBIM1 to integrate BR and JA signaling under cold stress. The E3 ubiquitin ligase MdATL73 targets MdBIM1 for degradation, reducing cold tolerance. This study reveals the crosstalk between BR and JA signaling and provides insights into the posttranslational regulation of BR signaling.

Summary: Rootstocks can improve the chilling tolerance of grafted cucumbers, but the effectiveness varies. A weak de-blooming rootstock "Yunnan figleaf gourd" was found to be superior to a strong de-blooming rootstock "Huangchenggen No. 2" in improving chilling tolerance of cucumbers.

Summary: In this study, it was confirmed that Solanum habrochaites, a wild tomato species used as rootstock, can enhance the cold tolerance of cultivated tomato scions. Transcriptome profiling revealed significant differences in the scion of homo- and heterografted seedlings, particularly in jasmonic acid (JA) biosynthesis and signaling pathways. Further experiments demonstrated that JA plays a crucial role in the cold tolerance of tomato grafts with S. habrochaites rootstock.

Summary: miR1320, a rice species-specific microRNA, regulates cold stress tolerance in rice by targeting the ethylene-responsive transcription factor OsERF096 and repressing the JA-mediated cold signaling pathway. The study provides insights into the regulatory mechanism of miR1320 and OsERF096 under cold stress and demonstrates the impact of OsERF096 on hormone content and signaling pathways.

Summary: The function of Sly-miR164a in improving postharvest chilling tolerance of tomato fruit was investigated. The results showed that overexpression of Sly-miR164a promoted postharvest chilling injury, while knockdown of Sly-miR164a reduced chilling injury and enhanced fruit firmness. The study provides valuable information for genetically modifying miR164a and controlling postharvest chilling injury in fruit.

Summary: Kale, a member of the Brassica oleracea L. crops, has gained global recognition for its high nutritional value and versatility. The diversity of different kale varieties and the effect of chilling on glucosinolate diversity and taste have been explored. This study found different patterns of glucosinolate change in different kale varieties after cold acclimation, suggesting that genetic and environmental factors both play a role in the composition of glucosinolate patterns in kale.

Summary: Climate change has driven the exploration of strategies to help plants adapt to different abiotic stressors, ensuring the production and quality of commercially important crops. Sorghum, as the fifth most important cereal crop, exhibits strong adaptation potential to various abiotic stressors, except for low temperatures. This review discusses recent research advancements in understanding the physiological, metabolic, and molecular mechanisms underlying sorghum's cold tolerance, as well as posing questions and opportunities for further investigation.

Summary: The freezing modes of water droplets on a cold plate surface under forced convection were experimentally studied. The formation mechanism of the peak freezing mode was analyzed, and a new peakless freezing mode was discovered. The results showed that stronger convective heat transfer on the windward side of the droplet caused the freezing droplet's solid-liquid interface to incline in the windward direction. In the peakless mode, freezing was driven by frosting around the solid-liquid interface, forming a peakless solidification slope. Increasing the airflow velocity transformed the freezing mode from peak to peakless, promoting ice nucleation on the droplet and delaying droplet solidification. The critical criterion for freezing mode transition was obtained.
