Molecules, Journal Year: 2025, Volume and Issue: 30(6), P. 1196 - 1196

Published: March 7, 2025

In recent years, there has been increasing interest in the study of extremophilic microorganisms, which include halophiles and halotolerants. These able to survive thrive optimally a wide range environmental extremes, are polyextremophiles. this context, one main reasons for studying them is understand their adaptative mechanisms stress caused by extreme living conditions. paper, fungal strain Penicillium chrysogenum P13, isolated from saline soils around Pomorie Lake, Bulgaria, was used. The effect elevated concentrations sodium chloride on growth morphology as well physiology model investigated. P. P13 demonstrated high tolerance NaCl, showing remarkable liquid agar media. order establish relationship between salt- oxidative stress, changes cell biomarkers such oxidatively damaged proteins, lipid peroxidation, levels reserve carbohydrates studied were evaluated. involvement antioxidant enzyme defense adaptive strategy halotolerant against NaCl

The transcriptional regulatory network of hormones and genes under salt stress in tomato plants (Solanum lycopersicum L.)

Frontiers in Plant Science, Journal Year: 2023, Volume and Issue: 14

Published: Feb. 6, 2023

Salt stress has become one of the main limiting factors affecting normal growth and development tomatoes as well fruit quality yields. To further reveal regulatory relationships between tomato hormones under salt stress, interaction TF genome-wide gene network were analyzed constructed. After treatment, levels ABA, SA, JA significantly increased, GA decreased, IAA tZ showed a trend first increasing then decreasing. The expression patterns hormone biosynthesis signal transduction related genes based on RNA-seq analysis, co-expression networks constructed using weighted analysis (WGCNA). specific transcription also systematically identified 20 hormone-related candidate associated with stress. In conclusion, we revealed relationship in transcriptome profiles network. A transcriptional regulation model consisted six types was proposed. Our study provided valuable insights into molecular mechanisms regulating tolerance tomatoes.

Strigolactone-Mediated Trehalose Enhances Salt Resistance in Tomato Seedlings

Horticulturae, Journal Year: 2023, Volume and Issue: 9(7), P. 770 - 770

Published: July 5, 2023

Strigolactones (SLs) are newly discovered plant hormones that modulate a variety of physiological and biochemical processes stress responses. In this study, SLs’ synthetic analog, GR24, significantly improved the growth tomato seedlings under salt stress, while synthesis inhibitor, TIS108, inversed positive role SLs, indicating SLs could effectively enhance salt-stress resistance in tomato. To further explore mechanism SL-modulated trehalose (Tre) response to Tre metabolism was analyzed during process. GR24 increased endogenous starch contents decreased glucose (Glu) level conditions. Additionally, TPS TPP activities were enhanced by activity THL inhibited stress; thereafter, biosynthesis-related genes, including TPS1, TPS2, TPP1, TPP2, also upregulated stress. However, function TIS108. Thus, results indicated expression levels or genes enzymes transcript related degradation, respectively, resulting an increase and, therefore, weakening toxicity seedlings.

Effects of exogenous glycine betaine and cycloleucine on photosynthetic capacity, amino acid composition, and hormone metabolism in Solanum melongena L.

Scientific Reports, Journal Year: 2023, Volume and Issue: 13(1)

Published: May 10, 2023

Abstract Although exogenous glycine betaine (GB) and cycloleucine (Cyc) have been reported to affect animal cell metabolism, their effects on plant growth development not studied extensively. Different concentrations of (20, 40, 60 mmol L −1 ) (10, 20, 40 ), with 0 as control, were used investigate the foliar spraying growth, photosynthesis, chlorophyll fluorescence, Calvin cycle pathway, abaxial leaf burr morphology, endogenous hormones, amino acid content in eggplant. We found that had best effect development; it increased fresh dry weight plants, density hairs, net photosynthetic rate key enzyme activity leaves, an elevating fluorescence parameters, indoleacetic (IAA) decreased abscisic (ABA) content, glutamate, serine, aspartate, phenylalanine contents. However, significantly inhibited growth; apical dominance disappeared, height weights significantly, hairs was hindered, activities inhibited, hormones IAA ABA decreased, conversion utilization arginine, threonine, affected. Combined experimental results phenotypes, 20 growth. In conclusion, different regulatory development.

Integrative analysis of transcriptome and metabolome reveal molecular mechanism of tolerance to salt stress in rice

BMC Plant Biology, Journal Year: 2025, Volume and Issue: 25(1)

Published: March 15, 2025

Salt stress is considered to be one of the major abiotic stresses influencing rice growth and productivity. To improve crop productivity in saline soils, it essential choose a suitable variety for mitigating salt gain deep understanding underlying mechanisms. The current study explored tolerance mechanism wild 'HD96-1 (salt resistive)' conventional 'IR29 sensitive)' by evaluating morph-physiological, transcriptomic, metabolomic approaches. Physiological data indicated that HD96-1 had higher chlorophyll content, photosynthetic efficiency, more stable Na+/K+, less H₂O₂, lower electrolyte leakage under compared with IR29. Transcriptomic showed expression NHXs IR29 was significantly down-regulated stress, leading large accumulation Na⁺ cytoplasm, CHLH, PORA, PORB down-regulated, inhibiting synthesis. maintained balance K⁺ increasing NHX4, there no significant change genes related synthesis, which made resistant than In addition, inhibited excessive synthesis hydrogen peroxide (H₂O₂) alleviated oxidative damage down-regulating ACX4 stress. promoted isoleucine up-regulating branched-chain amino acid aminotransferase 2 4 might promote raffinose stachyose gene galactitol synthase 2, which, turn, osmotic pressure relieved We also found inhibition photosynthesis light-harvesting chromophore protein complex (LHCH II)-related reducing glucose metabolites, respectively. enhances regulating C2H2 bHLH153 transcription factors.
