Published: April 22, 2025

Chromium (Cr) contamination poses severe risks to plant health and soil quality, requiring sustainable remediation methods. This study explored the synthesis of zirconia nanoparticles (PF-ZrO2 NPs) from Sonchus asper extract assessed their potential alleviate Cr toxicity in Chinese cabbage (Brassica rapa var. pekinensis). The characterization was performed through XRD, SEM, FTIR analyses, confirming crystalline nature, structure, surface chemistry. results indicated significant declines growth, chlorophyll content, biomass, nutrient uptake under stress (treatments T2 T4), accompanied by elevated oxidative indicators (H2O2, MDA) accumulation. application PF-ZrO2 NPs (T3 T5) notably reduced shoot concentrations (by 58.94% 35.90%) improved level 5.41% 14.41%). Additionally, increased antioxidant enzyme activity (SOD, POD, CAT) properties (pH, cation exchange capacity, retention). These findings suggest green-synthesized are effective, environmentally friendly candidates for contaminated soils.

Silicon enhances the growth of nickel-stressed cabbage plants by reducing oxidative damage and strengthening root architecture

International Journal of Phytoremediation, Journal Year: 2025, Volume and Issue: unknown, P. 1 - 11

Published: April 21, 2025

Nickel (Ni) toxicity can disorder plant growth and development, while silicon (Si) is important element in ameliorating heavy metal stress. This study investigated the effect of exogenous application Si (2 mM) on cabbage plants exposed to Ni (0.5 mM 1 mM). The impacts root morphology, enzymatic activities, proline glycine betaine (GB) accumulation, reactive oxygen species (ROS), other physiological parameters grown under stress were observed. Exogenous mitigated irreversible damage caused by improving enhancing regulating osmoprotectants (proline betaine), modulating ROC (O2- H2O2), supporting overall physiology. Furthermore, reduced content 67% 72% roots leaves, respectively, improved nutrients (Si, N, P, K) upregulation reducing oxidative findings suggest that foliar 2 enhance regulate nutrient uptake, play a crucial role accumulation. primarily attributed its contribution strengthening defense mechanisms against osmoregulation, thereby alleviating Ni-induced promoting growth.

Effect of Foliar Application of Sodium Selenate on Mineral Relationships in Brassicaceae Crops

Horticulturae, Journal Year: 2023, Volume and Issue: 9(5), P. 535 - 535

Published: April 27, 2023

The relationships of selenium (Se) with other elements in plants is important for producing functional food high Se contents and a predicted quality. To unveil the peculiarities element interactions, eight botanical varieties Brassica oleracea L. were grown similar conditions or without foliar application sodium selenate. High varietal differences, elicited by supply, recorded regard to accumulation examined, except Mg, P Si. Cabbage florets (broccoli cauliflower) characterized both lowest total mineral content number showing changes under supply (7–8 out 25), whereas Savoy cabbage, highest minerals displayed (13–14 from 25). treatment did not significantly interfere correlation coefficients between Sr–Ca, Co–Ni Zn–Mg (0.824–0.952). biofortification value varied 12 138 depending on species was inversely correlated Si control (r = −0.872, p < 0.001). A significant decrease occurred due regarding Zn Co, Ca Co Li, Li V, Na Sn, while V–Pb relationship enhanced. Among 25 studied, Cr demonstrated coefficient (with K, Na, P, Si, Zn, Cu, I, As, Pb, V). results this research prove variability interactions treatments reveal, first time, an inverse level untreated plants.

Published: Sept. 3, 2024

Chromium phytotoxicity results in relevant alterations to plant physiology, gene expression, and genomic DNA methylation at a transgenerational level. Herein, transcriptional responses of durum wheat (Triticum turgidum L.) chronic chromium exposure were explored roots leaves by RNA-seq approach. Plants grown all the time hydroponic system supplemented with 2.5 10 µM compared unstressful control plants, assessing biomass seed yield analyses after senescence. Then, transcriptomic analysis was performed these plants kept under 50 days onset exposure. The concentrations used considered lowest dose sufficient alter expression without impeding development, while sampling reflected effects pre-harvest phase long-lasting defense mechanisms. Root leaf samples from stress analyzed, generating 12 libraries. In total, 965 810 transcripts found be differentially expressed, respectively, root response stress. roots, changes noted primary secondary metabolism, redox homeostasis, protein modification, solute transport, nutrient uptake, external stimuli responses. Meanwhile, primarily hormone-related pathways, chromatin modifications, cell division, modification uptake. particular, metal uptake translocation pathways studied greater emphasis identify key proteins involved transport compartmentalization. Furthermore, several genes malate-derived organic acid biosynthesis, trace transport/detoxification/chelation, vacuolar compartmentalization liked responses, some them also associated two putative clusters. Therefore, clusters are suggested as valuable biotechnological targets for future proof-of-concept studies aimed genetic engineering improve tolerance
