“…These findings, therefore, further suggest the involvement of EgDREB1 in both cold and drought signaling of oil palm. Similar findings were observed in Arabidopsis, where CBF/DREB1 that was known to be involved only in cold signaling was also induced under drought, ABA treatment, and salinity ( Wang et al, 2014c ). Lowland tomato over-expressing EgDREB1 exhibited reduction in seed number, development of parthenocarpic fruits, alteration of leaves morphology, and increment of root biomass ( Azzeme et al, 2020 ).…”

Inflictions caused by cold stress can result in disastrous effects on the productivity and survival of plants. 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. This review discusses some of the latest understanding on the regulation of expression and the mechanistic actions of plant TFs to address cold stress response. It was shown that the plant response consists of early and late responses as well as memory reprogramming for long-term protection against cold stress. The regulatory network can be differentiated into CBF-dependent and independent pathways involving different sets of TFs. Post-transcriptional regulation by miRNAs, control during ribosomal translation process, and post-translational regulation involving 26S proteosomic degradation are processes that affect the cellular abundance of key regulatory TFs, which is an important aspect of the regulation for cold acclimation. Therefore, fine-tuning of the regulation by TFs for adjusting to the cold stress condition involving the dynamic action of protein kinases, membrane ion channels, adapters, and modifiers is emphasized in this review.

“…In addition, we also found some strongly induced TFs (FC value ≥ 2, P ≤ 0.05) in the leaves of yellowhorn. Among them, CBF/DREB-like 1 protein, a typical cold-induced TF, can also be induced by drought, ABA treatment and high salt to improve plant resistance (Wang et al 2014). Under N de ciency conditions, this TF showed high differential expression in yellowhorn, which has not been reported previously.…”

Nitrogen (N) deficiency affects various pathways in plants, while transcription factors (TFs) play crucial roles in regulating metabolic processes. However, there is restricted information about the activation of TFs in trees subjected to low-N stress. We assessed these functions by identifying and predicting TFs in yellowhorn, a high-quality raw material for the production of biodiesel, under low-N stress. We performed comparative transcriptome analysis to study the overall expression of TFs in yellowhorn under different N concentrations. A total of 56 TF families, including 1,873 TF genes, were identified. Among them, 410 (approximately 22%) TFs were detected at significantly higher or lower differential expression levels in both N deficiency treatments than in normal N conditions. We then sorted eight TF families (593 TFs) related to N stress based on previous studies and determined whether they respond to low-N stress. Further phylogenetic and conservative analyses showed that TFs in yellowhorn were clustered according to their phylogenetic affinity, providing a better understanding of their functional diversity. Protein interaction and Gene Ontology (GO) analyses predicted that TFs mainly functioned in hormone conduction, oxidative stress and defense responses. In addition, some TFs involved in salicylic acid signaling, jasmonic acid signaling and antioxidant stress pathways were significantly expressed, implying that these components may help yellowhorn adapt to N deficiency. This study contributes to a better understanding of the complex mechanism of TFs in response to low-N stress in yellowhorn and lays a foundation for exploring yellowhorn TFs genes involved in low-Nitrogen-responsive.

“…A number of candidate genes involved in low temperature adaptation are regulated by C-repeat binding factor/dehydration-responsive element binding (CBF/DREB1) transcription factors [140][141][142]. Genes encoding a family of cold-regulated (COR) proteins were used to identify a family of Arabidopsis transcription factors known as either C-repeat binding factors (CBF) (CBF1, 2, and 3) or dehydration-responsive element binding factors (DREB) (DREB1B, DREB1C, and DREB1A) [142,143].…”

“…Previous studies suggested that the toxicity of heavy metals disturbs redox homeostasis due to the overproduction of ROS such as singlet oxygen ( 1 O 2 ), superoxide radicals (O 2 − ), hydrogen peroxide (H 2 O 2 ), and hydroxyl radicals ( • OH) [8]. The plant's molecular response to heavy metal stress is characterized by the synthesis of stress-related amino acids, protein, genes, and signaling molecules [140]. A higher proline (Pro) level was found in the Cd-hyperaccumulator plant Solanum nigrum more than in the non-accumulator plant (Solanum melongena L), indicating its role in heavy metal detoxification [158,159].…”

The recent rapid climate changes and increasing global population have led to an increased incidence of abiotic stress and decreased crop productivity. Environmental stresses, such as temperature, drought, nutrient deficiency, salinity, and heavy metal stresses, are major challenges for agriculture, and they lead to a significant reduction in crop growth and productivity. Abiotic stress is a very complex phenomenon, involving a variety of physiological and biochemical changes in plant cells. Plants exposed to abiotic stress exhibit enhanced levels of ROS (reactive oxygen species), which are highly reactive and toxic and affect the biosynthesis of chlorophyll, photosynthetic capacity, and carbohydrate, protein, lipid, and antioxidant enzyme activities. Transgenic breeding offers a suitable alternative to conventional breeding to achieve plant genetic improvements. Over the last two decades, genetic engineering/transgenic breeding techniques demonstrated remarkable developments in manipulations of the genes for the induction of desired characteristics into transgenic plants. Transgenic approaches provide us with access to identify the candidate genes, miRNAs, and transcription factors (TFs) that are involved in specific plant processes, thus enabling an integrated knowledge of the molecular and physiological mechanisms influencing the plant tolerance and productivity. The accuracy and precision of this phenomenon assures great success in the future of plant improvements. Hence, transgenic breeding has proven to be a promising tool for abiotic stress improvement in crops. This review focuses on the potential and successful applications, recent progress, and future perspectives of transgenic breeding for improving abiotic stress tolerance and productivity in plants.
