Ozone Treatment as an Approach to Induce Specialized Compounds in Melissa officinalis Plants

Plants, Journal Year: 2024, Volume and Issue: 13(7), P. 933 - 933

Published: March 23, 2024

Plants are constantly subjected to environmental changes that deeply affect their metabolism, leading the inhibition or synthesis of “specialized” compounds, small organic molecules play a fundamental role in adaptative responses. In this work, Melissa officinalis L. (an aromatic plant broadly cultivated due large amounts secondary metabolites) plants were exposed realistic ozone (O3) dosages (80 ppb, 5 h day−1) for 35 consecutive days with aim evaluate its potential use as elicitor specialized metabolite production. Ozone induced stomatal dysfunction throughout whole experiment, associated low photosynthetic performance, decrease energy conversion activity PSII, and an alteration total chlorophyll content (−35, −36, −10, −17% average compared controls, respectively). The production hydrogen peroxide at 7 from beginning exposure (+47%) resulted lipid peroxidation visible injuries. This result suggests metabolic disturbance within cell concomitant homeostasis, probably limited activation antioxidative mechanisms. Moderate accumulated doses O3 triggered accumulation hydroxycinnamic acids up-regulation genes encoding enzymes involved rosmarinic acid, phenylpropanoid, flavonoid biosynthesis. While high significantly enhanced hydroxybenzoic acid flavanone glycosides. Our study shows application investigated concentration period (such two/three weeks) may become useful tool stimulate bioactive compounds M. officinalis.

Trivalent chromium stress trigger accumulation of secondary metabolites in rice plants: Integration of biochemical and transcriptomic analysis

Environmental Technology & Innovation, Journal Year: 2024, Volume and Issue: 36, P. 103802 - 103802

Published: Aug. 23, 2024

Trivalent chromium [Cr (III)] is a frequently detected environmental contaminant that negatively affects plant metabolism, growth, and yield. Plant secondary metabolites are non-nutrient compounds involved in diverse physiological functions response to abiotic stresses. This study performed biochemical transcriptomic analyses clarify the protective role mechanisms of rice seedlings under Cr(III) stress. The content measured i.e., total soluble phenolics, flavonoids, lignin, anthocyanin tissues was significantly enhanced exposure. Additionally, activities several enzymes including chalcone synthase, phenylalanine ammonialyase, peroxidase, anthocyanidin were positively activated. Transcriptomic analysis revealed number differentially expressed genes (DEGs) Cr(III)-treated their expression patterns tissue-specific. DEGs metabolism pathways evident after KEGG enrichment analysis. exposure resulted distinct genetic regulation strategies tissues, with different activating various sub-pathways cope Furthermore, integrated correlation transcriptome data identified key steps pathway plants indicates accumulation survival detoxification strategy reduce adverse effects toxic compounds. Future research should explore how aid enhance crop stress tolerance.
