“…PtrNAC006, PtrNAC007, and PtrNAC120, regulated by PtrAREB1, were shown to be positive regulators in drought response . In grapevine, several NAC TFs, including VvNAC26, VvNAC08, VvNAC17, and VaNAC17, were reported to enhance drought tolerance in Arabidopsis (Fang et al, 2016;Su et al, 2020;Ju et al, 2020a,b; Table 1). A novel CCCH zinc finger TF, PdC3H17, was found to positively regulate drought response in poplar.…”

Within the context of global warming, long-living plants such as perennial woody species endure adverse conditions. Among all of the abiotic stresses, drought stress is one of the most detrimental stresses that inhibit plant growth and productivity. Plants have evolved multiple mechanisms to respond to drought stress, among which transcriptional regulation is one of the key mechanisms. In this review, we summarize recent progress on the regulation of drought response by transcription factor (TF) families, which include abscisic acid (ABA)-dependent ABA-responsive element/ABRE-binding factors (ABRE/ABF), WRKY, and Nuclear Factor Y families, as well as ABA-independent AP2/ERF and NAC families, in the model plant Arabidopsis. We also review what is known in woody species, particularly Populus, due to its importance and relevance in economic and ecological processes. We discuss opportunities for a deeper understanding of drought response in woody plants with the development of high-throughput omics analyses and advanced genome editing techniques.

“…Various transcription factors affecting the JA pathway also have been utilized to manipulate drought tolerance of different plants (Table1). For instance, overexpression of grape VaNAC17 and VaNAC26 in Arabidopsis resulted in improved drought endurance by affecting JA biosynthesis and pathway-related genes such as LOX3, AOC1, OPR3, MYC2, JAZ1, VSP1, and CORI3(Fang et al, 2016;Su et al, 2020). Role of salicylic acid in drought stress SA is crucial for inducing local and systemic defense in plants, mainly upon pathogen attacks and under other stresses…”

Drought stress negatively affects crop performance and weakens global food security. It triggers the activation of downstream pathways, mainly through phytohormones homeostasis and their signaling networks, which further initiate the biosynthesis of secondary metabolites (SMs). Roots sense drought stress, the signal travels to the above-ground tissues to induce systemic phytohormones signaling. The systemic signals further trigger the biosynthesis of SMs and stomatal closure to prevent water loss. SMs primarily scavenge reactive oxygen species (ROS) to protect plants from lipid peroxidation and also perform additional defense-related functions.Moreover, drought-induced volatile SMs can alert the plant tissues to perform drought stress mitigating functions in plants. Other phytohormone-induced stress responses include cell wall and cuticle thickening, root and leaf morphology alteration, and anatomical changes of roots, stems, and leaves, which in turn minimize the oxidative stress, water loss, and other adverse effects of drought. Exogenous applications of phytohormones and genetic engineering of phytohormones signaling and biosynthesis pathways mitigate the drought stress effects. Direct modulation of the SMs biosynthetic pathway genes or indirect via phytohormones' regulation provides drought tolerance. Thus, phytohormones and SMs play key roles in plant development under the drought stress environment in crop plants. | INTRODUCTIONA large segment of the population is going to face food scarcity due to climate change and the gradually decreasing arable land area. Plants are confronted to a variable environment while growing from seedling to mature plant. Different abiotic and biotic stresses affect plant growth and development (Cramer et al., 2011;Fujita et al., 2006;Tuteja & Sopory, 2008). Abiotic stress includes drought, submergence, osmotic stress, salinity stress, oxidative stress, ultra-violet irradiation, wounding, and nutrient depletion. The extremity of optimum factors such as high temperature or low temperature and freezing-thawing is also included in abiotic stresses. Biotic stresses include viruses, bacteria, fungi, algae, worms, nematodes, insects, herbivores, and parasitic plants. Plants have to combat these stressors due to their sessile lifestyle (Cramer et al., 2011;Fujita et al., 2006). More than 50% reduction in average yields of major cereal crops has been reported because of various abiotic stresses. Drought is one of the most important abiotic stresses that negatively influence plant performance and causes harsh effects on biomass and yield (Fahad et al., 2017). A

“…NAC transcription factors increase stress tolerance in plants by modulating transcript levels of CBFs and their putative downstream such as COR / ERD / RD genes. One study showed that the function of VaNAC17 in a CBF-dependent signaling pathway induced drought stress tolerance by modulating the expression of stress-responsive genes [14]. NAC transcription factors participate in various signaling pathways to against with cold stress, so the study of NAC transcription factors is a prerequisite for improving the effects of stress on plants.…”

Background: Cold stress is one of the limitative factors of different species of crops on the planet, causing significant damage to the Iranian agricultural industry every year. Grapes are the product of temperate warm zones and sensitive to early autumn cold and spring cold. The current study the effects of cold stress (+1 °C for 4, 8, and 16 hours) on three grapevine cultivars (Ghiziluzum, Khalili, and Perllete) were investigated. Results: The results showed that cold stress caused significant changes in the antioxidant and biochemicals content in the studied cultivars. Furthermore, examining the chlorophyll fluorescence indices, cold stress caused a significant increase in minimal fluorescence (F0), a decrease in maximal fluorescence (Fm), and the maximum photochemical quantum yield of photosystem II (Fv/Fm) in all cultivars. According to the obtained results, among the three studied cultivars, ‘Perllete’ with the highest increase in proline content and the activity of antioxidant enzymes and also, having the lowest accumulation of malondialdehyde, hydrogen peroxide, electrolyte leakage, and F0 as well as less decrease in Fm and Fv/Fm had the higher tolerance to the cold stress than ‘Ghiziluzum’ and ‘Khalili’ cultivars. VvCBF4 and VvNAC1 genes expression was increased in all three cultivars at +1 °C at 8 hours and then decreased. The increase in VvCBF4 and VvNAC1 genes expression in ‘Perllete’ cultivar was higher than the other two cultivars. Conclusion: ‘Perllete’ and ‘Ghiziluzum’ showed the highest tolerance to low temperature stress, respectively. ‘Khalili’ was sensitive to low temperature stress.
