Freshwater plants are threatened by microplastics (MPs). While many studies have reported the effects of MPs on aquatic and animals, few examined plant metabolism at different light intensities. We explore cellular, metabolic, stress responses Vallisneria natans intensities (0, 20, 90, 160, 280 μmol·m-2·s-1), without with (50 mg·L-1) MPs. The experiment showed that strong promotes adsorption accumulation leaf root tissues, affected growth rate, changed metabolic pathways, inhibited photosynthetic processes, enhanced oxidative in V. natans. Metabolomic analysis experimental validation revealed combination μmol m-2·s-1 interfered most severely carbon nitrogen metabolism, lipid amino acid pathways compared 90 This condition also significantly activities photosynthesis energy transfer-related regulators proteins, as well stimulated stress-related exacerbated toxicity responses. results research indicate highest intensity tested can increase MPs, leading to cell damage, inhibition risk toxic stress. Our provide a basis for processes assessment under action

Rhizosphere Growth-Promoting Fungi of Healthy Nicotiana tabacum L.: A Systematic Approach to Boosting Plant Growth and Drought Resistance

Microorganisms, Год журнала: 2025, Номер 13(3), С. 543 - 543

Опубликована: Фев. 27, 2025

Drought, exacerbated by global warming, poses a significant threat to crop growth and productivity. This study identified strain of Trichoderma harzianum from the rhizosphere healthy Nicotiana tabacum L. plants evaluated its role in enhancing drought tolerance. The isolated effectively colonized plant roots promoted N. To investigate potential, T. was inoculated into under varying conditions, impact on growth, physiological responses, resilience assessed. Comprehensive analyses agronomic traits, parameters, enzyme activities, photosynthetic performance, osmoprotectant levels, membrane lipid peroxidation revealed that inoculation (light with harzianum, moderate severe treatments) systematically improved development resistance. These findings provide valuable insights lay foundation for developing innovative biofertilizers enhance tolerance sustainability.
