Abstract Drought stress can have negative impacts on crop productivity. It triggers the accumulation of reactive oxygen species, which causes oxidative stress. Limited water and nutrient uptake under drought also decreases plant growth. Using cobalt fulvic acid with biochar in such scenarios effectively promote Cobalt (Co) is a component various enzymes co-enzymes. increase concentration flavonoids, total phenols, antioxidant (peroxidase, catalase, polyphenol oxidase) proline. Fulvic (FA), constituent soil organic matter, increases accessibility nutrients to plants. Biochar (BC) enhance moisture retention, uptake, productivity during That’s why current study explored influence Co, FA BC chili plants This involved 8 treatments, i.e., control, 4 g/L (4FA), 20 mg/L sulfate (20CoSO ), 4FA + 20CoSO , 0.50%MFWBC (0.50 MFWBC), 0.50MFWBC, 0.50MFWBC.

Savory (Satureja rechingeri L.) is one of Iran's most important medicinal plants, having low irrigation needs, and thus considered the valuable plants for cultivation in arid semi-arid regions, especially under drought conditions. The current research was carried out to develop a genetic algorithm-based artificial neural network (ΑΝΝ) model able simulating levels antioxidants savory when using soil amendments [biochar (BC) superabsorbent (SA)] drought. Data different watering schemes showed that both BC SA have mitigating effects over stress by optimizing enzymatic non-enzymatic antioxidant traits (POD, CTA, APX enzymes). Specifically, biochar led improved homeostasis water deficit as reflected lower MDA levels. An ANN with 3-10-6 topology found be best predict polyphenols (PHE), proline (PRO), peroxidase (POX), catalase (CAT), ascorbate (APX) levels, indicator oxidative malondialdehyde (MDA). model's efficiency established R-value statistical parameter, simulated GA-ANN data were highly correlated experimental findings.

Enhancing drought tolerance in blackgram (Vigna mungo L. Hepper) through physiological and biochemical modulation by peanut shell carbon dots

Scientific Reports, Journal Year: 2025, Volume and Issue: 15(1)

Published: Feb. 14, 2025

Among the abiotic factors that causes threat to crop production, drought is one of foremost constraints in changing climatic era. Hence, a study was conducted mitigate effect stress blackgram with peanut shell carbon dots (PNS-CDs) as seed priming and foliar spray agent. Blackgram seeds were primed PNS-CDs at 200 ppm for 3 h plants sprayed 50 on 30th 45th DAS under conditions (30%, 50% 75% WHC). The imposed treatments included dry (control), water plants, PNS-CDs, combination both. results demarcate exemplary performance when given combined application (200 ppm) (50 terms its growth yield. Further, an increased activity catalase (12%), peroxidase superoxide dismutase (22%), glutathione reductase (60%), ascorbate (55%), H2O2 scavenging (32%) proline (35%) noticed over seeds, which confirmed antioxidant defense mechanism offered by PNS-CDs. In addition, percentage increase photosynthetic parameters like total chlorophyll (44%), soluble protein (54%), rate (89%), stomatal conductance (40%), internal CO2 concentration (74%) stability index (51%) role photosynthesis enhancer stress, resulted enhanced tolerance, plant Thus, it found followed 30 could serve sustainable alternative chemical inputs, ensuring better productivity tolerance water-limited environments. future research explore molecular mechanisms underlying different crops, biotic will also pave way broader agricultural sustainability eco-friendly approach.

SlRGLG2-SlBEL2 module regulates drought tolerance in tomato

Published: April 17, 2025

BEL1-LIKE HOMEODOMAIN (BLH/BELL) family transcription factors play important roles in the response of plants to environmental stress. In this study, we found that BLH/BELL factor SlBEL2 affects drought tolerance tomato plants, as SlBEL2-knockout (KO-SlBEL2) showed enhanced tolerance, whereas SlBEL2-overexpression (OE-SlBEL2) displayed impaired tolerance. Further research demonstrated negatively regulates by suppressing expression a number genes respond drought. addition, RING E3 ligase, SlRGLG2, interacts with and promotes ubiquitination degradation SlBEL2, thus affecting stability protein, which turn positively plants. summary, SlRGLG2-SlBEL2 module aforementioned findings offer novel viewpoint on plant's regulatory network.

Abstract Due to the high solubility of Cd in water, it is considered a potential toxin which can cause cancer humans. In plants, associated with development oxidative stress due generation reactive oxygen species. To overcome this issue, roles different plant hormones are vital. Strigolactones, one such natural hormones, show promise alleviating cadmium toxicity by mitigating its harmful effects. Acidified biochar (AB) also effectively mitigate via ion adsorption and pH buffering. However, combined effects strigolactone AB still need in-depth investigations context existing literature. This study aimed assess individual impacts SLs (0 25 µM) 0.75% w/w) on radish growth under toxicity, i.e., 0 20 mg Cd/kg soil. Using fully randomized design (CRD), each treatment was administered four replicates. comparison control soil contamination, results showed that µM + significantly improved following: shoot length (~ 17%), root 47%), fresh weight 28%), dry 96%), chlorophyll 43%), b 31%), total 37%).
