“…Among genes encoding the antioxidant system's enzyme, Glutathione S-transferase and Glutaredoxin showed the most significant change in expression for both studied cultivars and stress factors. Glutaredoxin shows a decrease in the expression of the most gene copies, consistent with other experiments (Díaz et al, 2019). It was shown for arabidopsis that glutaredoxin is an essential element in the abiotic stress response, and it has many copies with multidirectional changes in gene expression (Zuther et al, 2004).…”

“…They showed an increased expression of genes associated with dehydrin and proteins of late embryogenesis, as well as genes encoding transcription factors, such as genes with leucine repeats and EF-hand proteins, which regulate the efficiency of transcription of downstream protective genes. It was revealed that cold stress on durum wheat causes a decrease in the expression of Glutaredoxin genes, proteins associated with the calcium signal, and an increase in the expression of hormonal signal transduction genes (Díaz et al, 2019). However, in these works, the data were not compared with QTL.…”

Bread wheat (Triticum aestivum L.) is one of the most important agricultural plants wearing abiotic stresses, such as water deficit and cold, that cause its productivity reduction. Since resistance to abiotic factors is a multigenic trait, therefore modern genome-wide approaches can help to involve various genetic material in breeding. One technique is full transcriptome analysis that reveals groups of stress response genes serving marker-assisted selection markers. Comparing transcriptome profiles of the same genetic material under several stresses is essential and makes the whole picture. Here, we addressed this by studying the transcriptomic response to water deficit and cold stress for two evolutionarily distant bread wheat varieties: stress-resistant cv. Saratovskaya 29 (S29) and stress-sensitive cv. Yanetzkis Probat (YP). For the first time, transcriptomes for these cultivars grown under abiotic stress conditions were obtained using Illumina based MACE technology. We identified groups of genes involved in response to cold and water deficiency stresses, including responses to each stress factor and both factors simultaneously that may be candidates for resistance genes. We discovered a core group of genes that have a similar pattern of stress-induced expression changes. The particular expression pattern was revealed not only for the studied varieties but also for the published transcriptomic data on cv. Jing 411 and cv. Fielder. Comparative transcriptome profiling of cv. S29 and cv. YP in response to water deficit and cold stress confirmed the hypothesis that stress-induced expression change is unequal within a homeologous gene group. As a rule, at least one changed significantly while the others had a relatively lower expression. Also, we found several SNPs distributed throughout the genomes of cv. S29 and cv. YP and distinguished the studied varieties from each other and the reference cv. Chinese Spring. Our results provide new data for genomics-assisted breeding of stress-tolerant wheat cultivars.

“…Furthermore the study identified that a tial 621 mRNAs were being regulated through potential competitive regulation of ln and miRNA, highlighting an interesting intersection for these two pathway Low/freezing temperature regulation by lncRNAs is also observed in Arabi through the expression regulation of COLD-BINDING FACTOR 1 (CBF1) by the l SVALKA (SVK) [59], again identifying an interesting regulatory mechanism whic exist in cereals, as the CBF genes are well conserved. An increase in the num lncRNAs is also observed in durum wheat, with 31 lncRNAs being differentia pressed between cold (5 °C) and control conditions in the spring durum cultivar CB [60].…”

Temperature is a critical environmental signal in the regulation of plant growth and development. The temperature signal varies across a daily 24 h period, between seasons and stochastically depending on local environmental events. Extracting important information from these complex signals has led plants to evolve multiple temperature responsive regulatory mechanisms at the molecular level. In temperate cereals, we are starting to identify and understand these molecular mechanisms. In addition, we are developing an understanding of how this knowledge can be used to increase the robustness of crop yield in response to significant changes in local and global temperature patterns. To enable this, it is becoming apparent that gene regulation, regarding expression and post-transcriptional regulation, is crucial. Large transcriptomic studies are identifying global changes in spliced transcript variants and regulatory non-coding RNAs in response to seasonal and stress temperature signals in many of the cereal crops. Understanding the functions of these variants and targets of the non-coding RNAs will greatly increase how we enable the adaptation of crops. This review considers our current understanding and areas for future development.

“…miRNAs controlling the expression of stress-responsive mRNAs are blocked by binding of decoy lncRNAs. Number of lncRNAs have been reported to act as target mimics under various stresses for, e.g., 16 in cassava under cold and/drought stress (Li S. X. et al, 2017), 186 in wheat under cold stress (Diaz et al, 2019), 40 in Chinese cabbage under heat stress , and 3,560 in Barley under drought stress (Qiu et al, 2019). The number of target mimics and the number of miRNAs is not the same, indicating a complex network of cross-talk between miRNA and lncRNA.…”

Impacts of climate change like global warming, drought, flooding, and other extreme events are posing severe challenges to global crop production. Contribution of Brassica napus towards the oilseed industry makes it an essential component of international trade and agroeconomics. Consequences from increasing occurrences of multiple abiotic stresses on this crop are leading to agroeconomic losses making it vital to endow B. napus crop with an ability to survive and maintain yield when faced with simultaneous exposure to multiple abiotic stresses. For an improved understanding of the stress sensing machinery, there is a need for analyzing regulatory pathways of multiple stressresponsive genes and other regulatory elements such as non-coding RNAs. However, our understanding of these pathways and their interactions in B. napus is far from complete. This review outlines the current knowledge of stress-responsive genes and their role in imparting multiple stress tolerance in B. napus. Analysis of network cross-talk through omics data mining is now making it possible to unravel the underlying complexity required for stress sensing and signaling in plants. Novel biotechnological approaches such as transgene-free genome editing and utilization of nanoparticles as gene delivery tools are also discussed. These can contribute to providing solutions for developing climate change resilient B. napus varieties with reduced regulatory limitations. The potential ability of synthetic biology to engineer and modify networks through fine-tuning of stress regulatory elements for plant responses to stress adaption is also highlighted.
