A sustainable biosorbent from <i>A. negundo</i> (AN) biomass was prepared and its detoxification potential was investigated. MB at concentrations of up to 10 ppm caused significant phytotoxic effects on the physiological parameters of <i>Brassica oleracea var. acephala</i> and anatomical parameters of <i>A. cepa</i> L. Germination rate of <i>B. oleracea var. acephala</i> seeds decreased to 76% with increasing MB concentrations. Moreover, significant decreases were observed in fresh weight (760.17 ± 0.76 mg), dry weight (43.09 ± 0.1 mg), root (7.46 ± 0.04 cm), and shoot lengths (13.92 ± 0.09 cm). Significant alterations were observed in the cytogenetic parameters and oxidant-antioxidant dynamics, including superoxide dismutase (SOD), catalase (CAT), peroxidase (POD), malondialdehyde (MDA), and hydrogen peroxide (H₂O₂). Molecular interactions contributing to the observed phytotoxicity were revealed by molecular docking analysis of MB with the target receptors associated with <i>in vitro</i> parameters (alpha-amylase (AMY1), beta-amylase (BMY1), serine/threonine-protein kinase (CTR1), B-DNA dodecamer, catalase, peroxidase, and superoxide dismutase). AN biosorbent treatment significantly detoxified MB solutions, and improvements in the values of the tested physiological, anatomical, biochemical, and cytogenetic parameters were observed.

This research focuses on the degradation of an aquatic pollutant by deriving CQDs from green sources, as plant part-based CQDs possess the potential to degrade aquatic contaminants. In this study, we first examine the use of Dalbergia sissoo as a method for producing bare or unmodified carbon quantum dots (UCQDs) and S and N co-enriched carbon quantum dots (S, N-CQDs) through a straightforward, rapid, and single-step microwave process. EDX, FTIR, FESEM, XRD, and UV-Visible spectra were utilized to characterize CQDs. The zeta potential of as-synthesized CQDs was also measured. The photocatalytic activity of CQDs was studied by degrading a cationic dye known as Malachite Green (MG) dye, along with optimization of various factors, notably pH, dye concentration, and CQD volume, which were also tuned. S, N-CQDs reported outstanding photocatalytic capacity (95.12%) toward 15 ppm MG dye in bright sunlight at a pH of 9, employing 1 ml of photocatalyst.

However, the possible complex mechanisms by which MT mitigates salt toxicity and oxidative damage in cauliflower (<i>Brassica oleracea</i> L.) remain unclear. To fill this gap and clarify the pathway to salt stress resistance, the present study investigated the effects of exogenous 50 μM MT on growth, physiological, biochemical, and phyto-hormonal responses of cauliflower seedlings subjected to 200 mM NaCl-induced salinity stress. Our results revealed that salinity stress triggered a significant reduction in leaf and root biomass, chlorophyll and carotenoid pigments, gas exchange parameters, and K⁺ and Mg²⁺ ions indicators, while Na⁺ levels and hydrogen peroxide (H₂O₂) and malondialdehyde (MDA) concentrations were significantly elevated, suggesting that cauliflower plants were adversely affected by salt-induced oxidative stress. However, exogenous MT application alleviated the reductions in growth, biochemical parameters, and physiological functions, promoting melatonin content and reducing reactive oxygen species (ROS) accumulation and lipid peroxidation by enhancing photosynthetic efficiency and promoting the accumulation of osmoprotectants under salt stress. Moreover, MT suppressed salt-induced oxidative stress by declining oxidative indicators via enhancing antioxidants activities such as superoxide dismutase (SOD), peroxidase (POD), catalase (CAT), and ascorbate peroxidase (APX) enzymes as well as significantly increasing abscisic acid (ABA) levels in the leaves of cauliflower plants under saline stress. In conclusion, we propose that exogenous MT application significantly enhances the physiological and biochemical profiles of cauliflower plants by improving organic osmolytes and mitigating salt-induced oxidative stress. Likewise, the correlation analysis presented strong evidence and confirms a direct contribution of MT+NAA in the growth, physio-biochemical, and phyto-hormonal traits under severe saline stress.
