Abstract Water is the basic molecule in living beings, and it has a major impact on vital processes. Plants are sessile organisms with sophisticated regulatory network that regulates how resources distributed between developmental adaptation Drought‐stressed plants can change their survival strategies to adapt this unfavorable situation. Indeed, modify, change, modulate gene expression when grown low‐water environment. This occurs through several mechanisms affect of genes, allowing these resist dry regions. Epigenetic modulation emerged as factor transcription regulation drought stress‐related genes. Moreover, specific molecular epigenetic modifications certain genetic networks lead adapted responses aid plant's acclimatization during repeated stress. understanding plant severe environmental stresses, including drought, critical for biotechnological applications. Here, we first focused stress general We also discussed exposed water be passed down generations.

Low temperatures disrupt nitrogen metabolism in tobacco, resulting lower nicotine content the leaves. 24-epibrassinolide (EBR) is a widely used plant growth regulator known for its roles enhancing cold tolerance and metabolism. Nevertheless, it remains unclear whether EBR enhances leaf under low temperature conditions during mature stage of flue-cured tobacco. To investigate effects on 'Yunyan 87' four treatments (foliar spraying 0, 0.1, 0.2 0.4 mg·L− 1 solutions) were performed by using single-factor randomized complete block design. The result showed that foliar different concentrations notably improve agronomic economic traits tobacco to varying degrees, as well increase total treatment better results, with middle upper leaves after curing increasing 11.11% 19.90%, respectively, compared CK. Compared single EBR, compound containing α-Cyclodextrin Tween 80 prolongs effect promotes development plants. Combining CaCl2 ZnSO4·7H2O significantly resistance Furthermore, combining higher KH2PO4 more effective promoting maturation yellowing than those concentrations. This study provides new insights application regulating stress tolerance. integration α-Cyclodextrin, 80, CaCl2, showcases novel approach extending effectiveness regulators improving agricultural sustainability. these findings may be applicable other cold-sensitive crops, offering broader benefits resilience productivity temperatures. However, research focuses two cycles, without investigating long-term impact soil health, crop sustainability, ecosystem. And further needed elucidate molecular mechanisms content. Not applicable.
