“…Furthermore, the burst of ROS caused by cold produced the osmotic stress and oxidative stress, which result in cell damage and even death ( Hu et al., 2020 ). Actually, plants have evolved sophisticated mechanisms ( Table 2 ) to withstand cold stress ( Zheng S. et al., 2021 ).…”

Ethylene Responsive Factor (ERF) subfamily comprise the largest number of proteins in the plant AP2/ERF superfamily, and have been most extensively studied on the biological functions. Members of this subfamily have been proven to regulate plant resistances to various abiotic stresses, such as drought, salinity, chilling and some other adversities. Under these stresses, ERFs are usually activated by mitogen-activated protein kinase induced phosphorylation or escape from ubiquitin-ligase enzymes, and then form complex with nucleic proteins before binding to cis-element in promoter regions of stress responsive genes. In this review, we will discuss the phylogenetic relationships among the ERF subfamily proteins, summarize molecular mechanism how the transcriptional activity of ERFs been regulated and how ERFs of different subgroup regulate the transcription of stress responsive genes, such as high-affinity K+ transporter gene PalHKT1;2, reactive oxygen species related genes LcLTP, LcPrx, and LcRP, flavonoids synthesis related genes FtF3H and LhMYBSPLATTER, etc. Though increasing researches demonstrate that ERFs are involved in various abiotic stresses, very few interact proteins and target genes of them have been comprehensively annotated. Hence, future research prospects are described on the mechanisms of how stress signals been transited to ERFs and how ERFs regulate the transcriptional expression of stress responsive genes.

“…Similar results have been observed in 47 cold-responsive OfbHLHs (osmanthus fragrans) that show various expression patterns with a range of 0.5 (short) to 120 (long) h cold stress [ 47 ]. To date, the mechanism of how these small molecules interact and/or coordinate to bHLH -related signal transduction pathways is little known [ 48 ]. Thus, more specific and in-depth experiments with the bHLH family still need to proceed.…”

Alfalfa represents one of the most important legume forages, and it is also applied as an organic fertilizer to improve soil quality. However, this perennial plant is native to warmer temperate regions, and its valuable cold-acclimation-related regulatory mechanisms are still less known. In higher plants, the bHLH transcription factors play pleiotropic regulatory roles in response to abiotic stresses. The recently released whole genome sequencing data of alfalfa allowed us to identify 469 MsbHLHs by multi-step homolog search. Herein, we primarily identified 65 MsbHLH genes that significantly upregulated under cold stress, and such bHLHs were classified into six clades according to their expression patterns. Interestingly, the phylogenetic analysis and conserved motif screening of the cold-induced MsbHLHs showed that the expression pattern is relatively varied in each bHLH subfamily, this result indicating that the 65 MsbHLHs may be involved in a complex cold-responsive regulatory network. Hence, we analyzed the TFBSs at promoter regions that unraveled a relatively conserved TFBS distribution with genes exhibiting similar expression patterns. Eventually, to verify the core components involved in long-term cold acclimation, we examined transcriptome data from a freezing-tolerant species (cv. Zhaodong) in the field and compared the expression of cold-sensitive/tolerant subspecies of alfalfa, giving 11 bHLH as candidates, which could be important for further cold-tolerance enhancement and molecular breeding through genetic engineering in alfalfa.

“…Perception of cold stress on the plasma membrane activates Ca 2+ permeable channel that leads to the release of Ca 2+ inside the cell. However, the frequency, duration, and amplitude of calcium ions, combinedly known as calcium signature, depends on the strength of stress condition (Zheng et al, 2021). Ca 2+ imaging based on aequorin and yellow Cameleon has provided evidence of transient cold-induced Ca 2+ channel activation in Arabidopsis (Krebs et al, 2012;Sun et al, 2021).…”

“…Thus, increasing the saturation of membrane fatty acids is an effective way to generate cold resilient plants . Similarly, Modulation of several other genes and proteins belonging to plasma membrane have shown a significant increase in cold/freezing tolerance in transgenic plants in tobacco (MpRCI, Feng et al, 2009), rice (OsSMP1, Zheng et al, 2021), Arabidopsis (PsCor413pm2, Zhou et al, 2018), (Feng et al, 2009;Zhou et al, 2018;Zheng 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.
