The environmental conditions encompassing plants exert a significant impact on their appropriate growth and development. It is of utmost importance to investigate the mechanisms signaling cascades underlying tolerance abiotic stress in order enhance quality crops. Plant development processes are significantly impacted by stresses, which intricately linked surroundings. Plants exhibit prompt genetic metabolic network responses, mostly through networks involving transcription factors that respond stress, including WRKY, MYB, bZIP, AP2/EREBP, NAC. Among these WRKY TFs factors, fulfill pivotal function diverse range responses developmental mechanisms. greatly assist coping with stress. These oversee control several target gene categories active involvement numerous interaction W-box cis-acting elements located promoters genes. This research provides comprehensive analysis response mechanism In addition, we have explored state knowledge TFs' effects plants' such as drought, salt, high temperatures, cold. elucidates intricate molecular govern pathways modulate expression, thereby conferring upon plants. Moreover, summarized involved biotic TFs, hormonal routes like SA JA, aid inducing resistance coordinating defense against pathogens challenges. agricultural sustainability augment crop resilience towards strategies manipulate regulatory need be established.

Abstract Synergistic and antagonistic relationships between cytokinins other plant growth regulators are important in response to changing environmental conditions. Our study aimed determine the functions of SlHP2 SlHP3 , two members cytokinin signaling tomato, drought stress using CRISPR/Cas9‐mediated mutagenesis. Ten distinct genome‐edited lines were generated via Agrobacterium tumefaciens ‐mediated gene transfer confirmed through Sanger sequencing. Stress experiments conducted with these ( slhp2,3‐10 slhp2,3‐11 ), which harbored homozygous mutations both genes. The responses carrying genes under polyethylene glycol (PEG)‐induced examined morphological, physiological, biochemical, molecular methods. demonstrated enhanced water retention, reduced stomatal density, less oxidative damage compared wild‐type plants PEG‐induced stress. Moreover, slhp2,3 double mutant exhibited improved root growth, showcasing their superior tolerance over by accessing deeper sources maintaining hydration water‐limited environments. To investigate involvement associated formation differentiation, expression Speechless [ SPCH ], FAMA MUTE TMM HB25 HB31 RR6 RR7 Solyc02g080860 ) was assessed. results revealed that all downregulated, showing significant reductions These emphasize promise utilizing CRISPR/Cas9 target pathways, enhancing tomatoes improvements retention along a reduction density malondialdehyde content.

SUMMARY Wolfberry ( Lycium barbarum L.) fruit, renowned for its high carotenoid content, is extensively used in traditional Chinese herbal medicine and cuisine. Drought a significant global challenge to crop production, with carotenoids playing crucial roles enhancing drought resistance higher plants. ζ ‐Carotene desaturase (ZDS), key enzyme the biosynthesis pathway, catalyzes conversion of ‐carotene lycopene. However, molecular mechanisms by which LbZDS responds stress remain largely unexplored. In this study, we demonstrated that transcription induced PEG, NaCl, abscisic acid (ABA) treatments. Overexpression both wolfberry tomato plants conferred enhanced tolerance promoting ABA synthesis. We further identified NAC factor LbNAM2 directly binds promoter region activates expression, as evidenced electrophoretic mobility shift assays, yeast one‐hybrid dual‐luciferase assays. Silencing , or dual silencing via virus‐induced gene (VIGS), severely compromised Additionally, overexpression resulted marked increase while either together led reduced levels. conclusion, our study provides critical insights into functional regulatory LbNAM2– module response wolfberry.

Populus wulianensis mainly grows in hilly and sloped areas has strong resistance to adversity. Previous transcriptome studies have shown that a WRKY gene PwuWRKY48 is expression-induced under drought stress. In this study, we aim characterize the gene’s structure investigate its role plant resistance. The results show (1113 bp) belongs class IIc subfamily it was determined as nuclear localization protein. promoter region contains variety of cis-elements relation stress Under stress, leaves stems, 29.7 16.6 times those before treatment, respectively. Overexpressing lines were associated with increased activities peroxidase (POD) superoxide dismutase (SOD), 2.5 1.6 higher than wild type. While malondialdehyde content (MDA), anion radical (O2·−), relative conductivity decreased by 20%, 30%, 21.3%, proline chlorophyll contents 37.5% 11.2%, This indicates efficiently improved tolerance transgenic plants. can be used resource for molecular breeding
