NO and melatonin interplay augment Cd‐tolerance mechanism in eggplants: ROS detoxification and regulation of gene expression

Physiologia Plantarum, Journal Year: 2025, Volume and Issue: 177(1)

Abstract Global crop productivity is consistently threatened by cadmium (Cd) soil contamination. Crosstalk between nitric oxide (NO) and melatonin (MT) in enhancing resilience to heavy metal stress has gained significant attention. Here, we evaluated the joint effect of sodium nitroprusside (SNP; 200 μM as NO donor) MT (100 μM) on Cd‐stressed eggplant ( Solanum melongena L.). Cd significantly reduced plant growth, biomass yield, leaf pigments, biochemical properties. Conversely, SNP, MT, particularly their combined (SNP + MT) application toxicity enhanced growth physio‐biochemical traits eggplants. For instance, at 50 mg kg −1 soil, SNP increased root (41.6, 30, 47%), total chlorophyll (30.7, 26.3, 46%), soluble protein (20.5, 17.6 37%) RLWC (23, 17.5, 29%) over respective control. Furthermore, p ≤ 0.05) levels EL, H 2 O , proline, MDA 54.5, 66, 61 70%, respectively, interplay antioxidant defense responses tissues under stress. Besides, upregulated transcript POD SOD CAT GPX genes eggplants applications improved essential nutrient cation homeostasis shoot Moreover, lessens metal‐induced decreasing uptake, translocation (TF) bioconcentration (BCF) factors. Conclusively, these findings validated beneficial defensive interaction regulating tolerance However, further research needed uncover underlying mechanisms synergistic effects.

Enhancing Pea Plant Growth, Nutrient Acquisition, and Symbiosis in Cobalt‐Stressed Soil Using Metal‐Tolerant Klebsiella sp.

Journal of Basic Microbiology, Journal Year: 2025, Volume and Issue: unknown

Published: March 28, 2025

ABSTRACT Excessive cobalt (Co) levels in agricultural soil cause significant toxicity, reducing crop growth and yield. This study aimed to assess the potential of Klebsiella sp. SRB‐5 (Accession no. OR715782), mitigating toxicity enhancing garden peas under stress. Strain SRB‐5, tolerant 4000 ppm Co(II), was evaluated for producing growth‐regulating substances, including indole‐3‐acetic acid (IAA), ammonia, siderophore, ACC deaminase, solubilized phosphate, The optimal conditions Co‐(II) biosorption by were determined be 25°C, pH 6.0, an incubation time 72 h. strain's ability mitigate tested inoculating grown treated with 1000, 2000, 3000 Co‐(II). Inoculation Co‐tolerant alleviated significantly enhanced physiological biochemical properties plants. Notably, increased root length (19.2%), biomass (29%), seedling vigor index (18.4%), total chlorophyll (52%), nodule (41%), leghaemoglobin content (38%), nitrogen (27%), phosphorous (19.3%) 1000 Co‐stressed peas. Additionally, bacterial inoculation reduced proline, malondialdehyde (MDA), hydrogen peroxide (H 2 O ), membrane injury 85%, 57.3%, 90%, 75%, respectively, Co‐exposed Priming also uptake roots (88%), shoots (53.7%), grains (79.6%) compared uninoculated treatments. Metal‐tolerant beneficial bacteria, such as strain could serve effective alternative pea production metal‐contaminated soils. use PGPR strains holds development biofertilizers future practices.

Exopolysaccharide-Producing Bacteria Regulate Soil Aggregates and Bacterial Communities to Inhibit the Uptake of Cadmium and Lead by Lettuce

Microorganisms, Journal Year: 2024, Volume and Issue: 12(11), P. 2112 - 2112

Published: Oct. 22, 2024

The accumulation of heavy metals in the soil not only causes serious damage to ecosystem, but also threatens human health through food chain. Exopolysaccharides have functions adsorbing and chelating reducing their bioavailability soil. In our study, exopolysaccharide-producing bacteria with a high efficiency cadmium (Cd) lead (Pb) were screened from metal-contaminated farmland. Through pot experiments, influence functional strains on size distribution, metal content, bacterial community structure aggregates lettuce was studied using high-throughput sequencing technology. results show that 11 secreting exopolysaccharides initially Among them, strain Z23 had removal rate 88.6% for Cd 93.2% Pb. at which removed by Z39 92.3%, Pb 94.4%.
