“…Once the temperature goes below the optimum, the COR gene springs into action to maintain homeostasis by mitigating the impact of cold stress. The first type of COR gene-dependent response involves encoding proteins required for the biosynthesis of osmoprotectants, cryoprotectants, protein kinases, lipid, hormone, and stress-responsive proteins like AFPs, HSPs, LEA, dehydrins that are directly involved in cold tolerance (Holmberge and Bülow, 1998;Thomashow, 2010;Kidokoro et al, 2022). Other sets of COR gene-dependent responses include genes such as early response to dehydration, low temperature-induced, response to abscisic acid, and cold-Induced transcription factors (Alves et al, 2011;Shi et al, 2015;Cao et al, 2021).…”

Cold stress adversely affects plant growth, development, and yield. Also, the spatial and geographical distribution of plant species is influenced by low temperatures. Cold stress includes chilling and/or freezing temperatures, which trigger entirely different plant responses. Freezing tolerance is acquired via the cold acclimation process, which involves prior exposure to non-lethal low temperatures followed by profound alterations in cell membrane rigidity, transcriptome, compatible solutes, pigments and cold-responsive proteins such as antifreeze proteins. Moreover, epigenetic mechanisms such as DNA methylation, histone modifications, chromatin dynamics and small non-coding RNAs play a crucial role in cold stress adaptation. Here, we provide a recent update on cold-induced signaling and regulatory mechanisms. Emphasis is given to the role of epigenetic mechanisms and antifreeze proteins in imparting cold stress tolerance in plants. Lastly, we discuss genetic manipulation strategies to improve cold tolerance and develop cold-resistant plants.

“…Additionally, to combat the cold-induced damage, some plants developed a unique process called cold acclimation where plants can acquire enhanced resistance to freezing stress when they are exposed to nonlethal low temperatures for a few days [ 21 ]. Various aspects of cold stress and the underlying mechanisms linked to these processes including transcriptional regulation, calcium signaling, the role of small molecules, and epigenetic regulation have been extensively covered in some recent reviews [ 22 , 23 , 24 , 25 , 26 , 27 ]. For chilling or low-temperature stress responses in plants, C-repeat-binding factors (CBF)-mediated pathway is the most studied one and is considered as the primary regulatory pathway [ 28 ].…”

Unlike animals, plants are unable to escape unfavorable conditions, such as extremities of temperature. Among abiotic variables, the temperature is notableas it affects plants from the molecular to the organismal level. Because of global warming, understanding temperature effects on plants is salient today and should be focused not only on rising temperature but also greater variability in temperature that is now besetting the world’s natural and agricultural ecosystems. Among the temperature stresses, low-temperature stress is one of the major stresses that limits crop productivity worldwide. Over the years, although substantial progress has been made in understanding low-temperature response mechanisms in plants, the research is more focused on aerial parts of the plants rather than on the root or whole plant, and more efforts have been made in identifying and testing the major regulators of this pathway preferably in the model organism rather than in crop plants. For the low-temperature stress response mechanism, ICE-CBF regulatory pathway turned out to be the solely established pathway, and historically most of the low-temperature research is focused on this single pathway instead of exploring other alternative regulators. In this review, we tried to take an in-depth look at our current understanding of low temperature-mediated plant growth response mechanism and present the recent advancement in cell biological studies that have opened a new horizon for finding promising and potential alternative regulators of the cold stress response pathway.

“…Tang and coworkers (Tang et al, 2020) pointed out several alternative explanations for the ice mutant findings and we agree with their conclusion that ICE proteins can play a role in increasing low temperature tolerance. However, AtCBFs can also be activated by other proteins such as AtCAMTAs (CALMODULIN BINDING TRANSCRIPTION ACTIVATORS) or AtHY5 (ELONGATED HYPOCOTYL 5), and even a CBF‐independent pathway can lead to increased low temperature tolerance (Kidokoro et al, 2022; Wang et al, 2022). It seems likely that the extent to which ICE is involved in cold acclimation in nature varies between different plant species.…”

INDUCER OF CBF EXPRESSION (ICE) proteins reportedly have a role in cold acclimation and stomata development, but the former has recently been questioned. Our aim was to analyze ICE, OPEN STOMATA 1 (OST1) and MITOGEN ACTIVATED PROTEIN KINASE 3/6 (MPK3/6) protein data and place the results in context with reports in the literature. Orthologous protein sequences from species representative of different plant lineages were retrieved via BLAST searches and assembled into multiple sequence alignments for a comprehensive comparison of key features. We identified one type of ICE protein in bryophytes, lycophytes, ferns and angiosperms, and a second type of ICE protein in angiosperms only, each with characteristic interaction domains. Due to the higher observed similarity of the identified orthologs to proteins from Vitis riparia than to those from Arabidopsis, they were referred to as VrICE2L and VrICE4L, respectively. Regulatory sequence motifs for the kinase OST1 were present in the VrICE2L proteins although less conserved in the non‐angiosperms, whereas OST1 orthologs could be identified in all plant species, including algae. Interestingly, MPK3/6 motifs were most clearly conserved in the VrICE2L and VrICE4L proteins of the more evolved angiosperms, at a time that the A subtype of MPK3/6 kinases and the CRT‐BINDING FACTOR (CBF)‐encoding genes first appeared in the plant lineages. These data are intended to stimulate further investigations of VrICE4L proteins in non‐model plants and provide some evolutionary context into the overlap between stomatal function and regulation, and the cold acclimation pathway.
