“…Cold stress response in plants requires crosstalk between multiple signaling pathways including cold, heat, and reactive oxygen species (ROS) signaling networks. CBF, MYB, bHLH, and WRKY families are among the TFs that function as key players in the regulation of cold stress response at the molecular level [ 139 , 140 ].…”

Olive (Olea europaea L.) is an evergreen xerophytic tree characterizing vegetative landscape and historical-cultural identity of the Mediterranean Basin. More than 2600 cultivars constitute the rich genetic patrimony of the species cultivated in approximately 60 countries. As a subtropical species, the olive tree is quite sensitive to low temperatures, and air temperature is the most critical environmental factor limiting olive tree growth and production. In this present review, we explored the detrimental effects caused of low temperatures on olive cultivars, and analyzed the most frequently experimental procedures used to evaluate cold stress. Then, current findings freezing stress physiology and gene are summarized in olive tree, with an emphasis on adaptive mechanisms for cold tolerance. This review might clear the way for new research on adaptive mechanisms for cold acclimation and for improvement of olive growing management.

“…Transcription factors (TFs) play a vital role in the response to all abiotic stresses, including chilling and high light (reviewed by Abdullah, Azzeme and Yousefi, 2022, Sharma et al, 2020, Wang et al, 2016). With this in mind, the TFs and enriched TF binding motifs present in the WGCNA module gene lists were investigated to find candidates that could be responsible for the mitigating effect of high light treatment on the transcriptome signature and stress response of chilling.…”

“…As expected, most of the highly represented TF families from modules three and four were different from those in modules one and two. All of the highly represented TF families in both gene lists are well known for modulating abiotic stress responses (Abdullah, Azzeme and Yousefi, 2022, Sharma et al, 2020, Wang et al, 2016).…”

“…The global transcriptome analyses above identified groups of genes and physiological responses that are significantly impacted during chilling and show a diminished response in the combination with high light. TFs are master regulators of chilling stress responses and can be manipulated to alter tolerance (reviewed: Abdullah, Azzeme and Yousefi, 2022, Sharma et al, 2020, Wang et al, 2016). To identify TFs with the potential to be key drivers of the transcriptional changes observed in modules one, two, three and four, we filtered for TFs which were present in the modules of interest (Table 1 and 2), had enriched binding motifs in the promoters of genes in the same module (Table 3 and 4) and had high kME values for the module in which they belonged (indicating a high level of centrality or connectivity with the other genes in the module).…”

High light can alleviate chilling stress in maize

Chilling stress has the potential to significantly decrease growth and yield of sensitive crop plants such as maize. Based on previous work, high light during chilling may exacerbate stress via enhanced photoinhibition but may also aid acclimation responses to chilling. To further understand molecular processes behind responses to chilling with and without high light, two maize accessions with contrasting tolerance (B73 and F7) were exposed to three treatments: chilling, chilling combined with high light and high light alone. Transcriptome data indicated that the chilling treatment resulted in the largest stress response. Addition of high light to chilling stress had a mitigating, rather than additive effect on stress, as evident from alleviated repression of photosynthesis-related genes and less induction of stress-related pathways such as abscisic acid signalling and senescence compared with the response to chilling alone. Five transcription factors belonging to well-known stress-related transcription factor families were identified as candidates for driving the transcriptional changes behind the high-light induced mitigation of chilling stress. Physiological measurements of non-photochemical quenching and the maximum quantum efficiency of photosystem II corroborated the transcriptome results, showing that the addition of high light alleviated photoinhibition and membrane damage caused by chilling. High light alone had little effect on the plant transcriptome or physiological response. Overall, this study overturns previous reports, offers a new outlook on the impact of high light during chilling stress and has the potential to provide clearer targets for crop engineering.

“…The activity of proteins can be affected at many levels (Abdullah et al, 2022; Wang et al, 2022; Wisniewski et al, 2018), including regulation of transcript levels, regulation of translation efficiency and post‐translational regulation. Research on Arabidopsis has uncovered how AtICE activity can be regulated, and the same strategies seem largely conserved in other plants.…”

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.
