ABSTRACT Members of the cyclic nucleotide‐gated channel (CNGC) proteins are reportedly involved in a variety biotic and abiotic responses stomatal movement. However, it is unknown if how single member could regulate multiple responses. Here we characterized three closely related CNGC genes rice, OsCNGC14 , OsCNGC15 OsCNGC16 to determine whether they function stresses. The loss‐of‐function mutants each these had reduced calcium ion (Ca 2+ ) influx slower closure response heat, chilling, drought stress hormone abscisic acid (ABA). These also tolerance chilling compared with wild‐type. Conversely, overexpression led more rapid stresses enhanced drought. tight association strongly suggests that conferred by OsCNGC results at least partially from their regulation In addition, physical interactions were observed among but not distantly CNGC, suggesting formation hetero‐oligomers themselves. This study unveils crucial role OsCNGC14, 15 16 stresses, mechanism involves movement regulation.

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.

The increasing prevalence of drought events poses a major challenge for upcoming crop production. Melatonin is tiny indolic tonic substance with fascinating regulatory functions in plants. While plants can respond several ways to alleviate stress, the processes underpinning stress sensing and signaling are poorly understood. Hereafter, objectives this investigation were explore putative melatonin regulation sugar metabolism abscisic acid biosynthesis drought-stressed tomato seedlings. (100 μM) and/or water foliar sprayed, followed by being imposed 14 days. Drought significantly decreased biomass accumulation, inhibited photosynthetic activity, stimulated senescence-associated gene 12 (SAG12) expression. treatment effectively reversed drought-induced growth retardation as evidenced increased leaf pigment balance restricted (ABA) accumulation. Sugar particularly sucrose content, was higher drought-imposed seedlings, possibly owing transcription levels non-fermenting 1-related protein kinase 2 (SnKR2.2) ABA-responsive element binding factors (AREB2). addition further uplifted which coincided activity synthase (SS, 130%), phosphate (SPS, 137%), starch degradation encoding enzyme β-amylase (BAM, 40%) α-amylase (AMY, 59%) upregulated their BAM1(10.3 folds) AMY3 (8.1 genes expression at day relative control.

Low-temperature stress, including chilling and freezing injuries, significantly impacts plant growth in tropical temperate regions. Plants respond to cold stress by activating mechanisms that enhance tolerance, such as regulating photosynthesis, metabolism, protein pathways producing osmotic regulators antioxidants. Membrane stability is crucial, with cold-resistant plants exhibiting higher lipid unsaturation maintain fluidity normal metabolism. Low temperatures disrupt reactive oxygen species (ROS) leading oxidative damage, which mitigated antioxidant defenses. Hormonal regulation, involving ABA, auxin, gibberellins, others, further supports adaptation. also manage balance accumulating like proline sugars. Through complex regulatory pathways, the ICE1-CBF-COR cascade, optimize gene expression survive ensuring adaptability conditions. This study reviews recent advancements genetic engineering technologies aimed at enhancing resistance of agricultural crops. The goal provide insights for improving tolerance developing new cold-tolerant varieties.
