Abstract Introduction Hydroponics enables precise control over nutrient delivery, optimized water requirements and growing conditions. The combination of nanotechnology hydroponics paves the way towards sustainable agriculture with less environmental footprints. We investigated effects nano urea on model plant Arabidopsis thaliana in hydroponics. Methods A growth experiment a nitrogen-free hydroponic medium compared liquid formulation (NUF) marketed by Indian Farmers Fertilizer Cooperative (IFFCO) to an equimolar bulk urea. Transcriptome analysis identified molecular mechanisms enhancement. Dynamic light scattering transmission electron microscopy confirmed NUF’s negative surface charge sub-100 nm size, correlating its uptake distribution plant. Results discussion two-week 70 μM NUF led 20% higher biomass 16% chlorophyll content than Higher doses inhibited growth, whereas equivalent did not. differential expression more genes at 12 h seven days treatment. Nitrogen assimilation, photosynthesis, stress tolerance showed transcript levels On other hand, greater suppression many growth-regulating genes. After treatment, biosynthesis got up-regulated, while catabolism down-regulated urea, NUF-treated seedlings. In conclusion, outperformed for promotion A. low concentration hydroponics, leading regulation nitrogen metabolism biosynthesis. Our results suggest potential use as fertilizer agriculture.

Salt Stress-Induced Modulation of Porphyrin Biosynthesis, Photoprotection, and Antioxidant Properties in Rice Plants (Oryza sativa)

Antioxidants, Journal Year: 2023, Volume and Issue: 12(8), P. 1618 - 1618

Published: Aug. 15, 2023

Salt stress disrupts cellular ion homeostasis and adversely impacts plant growth productivity. We examined the regulatory mechanisms of porphyrin biosynthesis, photoprotection, antioxidant properties in salt-stressed rice seedlings. In response to 150 mM NaCl, seedlings exhibited dehydration, reduced relative water content, increased levels conductivity, malondialdehyde, H2O2. The expression salt-stress-responsive genes NHX1, SOS1, MYB drastically after NaCl treatment. grown under displayed declines Fv/Fm, ΦPSII, rETRmax, photochemical quenching but increases nonphotochemical (NPQ) involved zeaxanthin formation, BCH, VDE. Under salt conditions, chlorophyll precursors significantly decreased compared controls, matching downregulation CHLD, CHLH, CHLI, PORB. By contrast, treatment led heme content at 24 h significant upregulations FC2, HO1, HO2 controls. Salt-stressed also their CATs (catalases) APXs (ascorbate peroxidases) as well activities superoxide dismutase, CAT, APX, peroxidase. Our results indicate that biosynthesis involve protective strategies for alleviation through photoprotection by scavenging NPQ activating enzymes.

Integrating Proteomics and Metabolomics Approaches to Elucidate the Mechanism of Responses to Combined Stress in the Bell Pepper (Capsicum annuum)

Plants, Journal Year: 2024, Volume and Issue: 13(13), P. 1861 - 1861

Published: July 5, 2024

Bell pepper plants are sensitive to environmental changes and significantly affected by abiotic factors such as UV-B radiation cold, which reduce their yield production. Various approaches, including omics data integration, have been employed understand the mechanisms this crop copes with stress. This study aimed find metabolic in bell stems caused cold integrating omic data. Proteome metabolome profiles were generated using liquid chromatography coupled mass spectrometry, integration was performed plant pathway database. The combined stress of induced accumulation proteins related photosynthesis, mitochondrial electron transport, a response stimulus. Further, production flavonoids glycosides, well affecting carbon metabolism, tetrapyrrole, scopolamine pathways, identified. We made first regulatory network map showing how respond did looking at metabolites that help respiration, buildup photoprotective antioxidant compounds.
