Salt stress, as a significant adverse consequence of global climate change, severely restricts the yield and quality watermelon. In this study, salt-tolerant cultivar T23 salt-sensitive B2 were subjected to 200 mM NaCl treatment (0 h, 6 24 48 168 h) at three-leaf stage, adaptation mechanisms watermelon roots salt stress systematically investigated phenotypic, physiological, gene transcription levels. Phenotypic observations revealed that inhibited seedling growth, caused leaf curling, induced root yellowing, with damage being significantly more severe in than T23. Compared B2, activities superoxide dismutase (SOD) increased by -7.13%, 169.15%, 34.95%, 84.87%, 39.87% under 0 respectively. h treatment, proline content 4.25%, 14.39%, 110.00% respectively, while showed increases 93.74%, 177.55%, 380.56% corresponding time points. The provided physiological data demonstrate exhibits superior antioxidant osmoregulatory abilities relative B2. transcriptome analysis identified differentially expressed genes (DEGs) between two cultivars showing highest number DEGs exhibited increase h. Gene Ontology (GO) Kyoto Encyclopedia Genes Genomes (KEGG) enrichment metabolic pathways such plant hormone signal transduction, terpenoid biosynthesis, mitogen-activated protein kinase (MAPK) signaling pathways, transporter activity, regulator activity play important roles response. Furthermore, yeast overexpression experiments preliminarily validated critical tonoplast dicarboxylate ClCG01G010280 NAC factor ClCG05G024110 tolerance. This study provides new molecular insights into tolerance mechanism offers potential genetic resources for breeding varieties.

Transcriptome Analysis Revealed the Response Mechanism of Pomegranate to Salt Stress

Agronomy, Год журнала: 2024, Номер 14(10), С. 2261 - 2261

Опубликована: Окт. 1, 2024

Pomegranate (Punica granatum) is a well-known fruit tree species and significant pioneer ecological on saline–alkali land with moderate resistance to salt stress. To explore its response mechanism stress could provide valuable insights into the molecular physiological strategies plants employ adapt survive in high-salt environments. In this study, changes parameters gene expressions were examined following treatment. After 72 h of treatment, change patterns SOD POD differed between high low concentrations. Similar found contents proline total soluble sugar. RNA-Seq analysis fifteen samples detected 32,630 genes from pomegranate genome data. A 6571 DEGs, including 374 TFs, identified across different treatments. Six special modules 180 hub obtained by WGCNA analysis. Functional annotation highlighted signaling pathways accumulation primary secondary metabolites as pathways. These findings reveal tolerance leaves, offering theoretical foundation for enhancing plant through genetic engineering.

Melatonin induces drought stress tolerance by regulating the physiological mechanisms, antioxidant enzymes, and leaf structural modifications in Rosa centifolia L.

Melatonin is considered an effective bio-stimulant that crucial in managing several abiotic stresses including drought. However, its potential mechanisms against drought stress fragrant roses are not well understood. Here, we aim to investigate the role of melatonin on Rosa centifolia plants cultivated under (40 % field capacity) and normal irrigation (80 capacity). Plant growth traits, gaseous exchange, antioxidants, osmolytes, oxidative stress, leaf anatomical attributes were measured. All pots arranged with a completely randomized design two-factor factorial setup. Foliar application was carried out next day treatment repeated weekly, while watering regarded as control. Drought significantly enhanced markers reduced parameters water-deficit rose plants. spray (100 μM) produced increased plant height (16 %), flower yield petal fresh dry biomass (7 38 total chlorophyll (48 contents carotenoid (54 exchange traits such stomatal conductance (25 photosynthetic rate (91 transpiration (3 water-deficient Likewise, accretion catalase, superoxide dismutase, soluble protein, proline, glycine betaine recorded by 22 %, 45 58 7 6 respectively, drought-stressed plants, due treatment.
