Saponin content in medicinal plants in response to application of organic and inorganic fertilizers: a meta-analysis

Frontiers in Plant Science, Journal Year: 2025, Volume and Issue: 16

Published: Feb. 11, 2025

The application of fertilizers is a key agronomic practice in the artificial cultivation medicinal plants, aiming to boost yields and enhance levels their bioactive constituents. However, systematic investigations on influence various concentration active compounds saponin-containing plants remain insufficient. In this study, 966 experimental outcomes from 29 papers were analyzed via meta-analysis examine effects organic fertilizers, inorganic combined different saponin monomers plants. findings revealed that contribute positively accumulation saponins such as Rg1 ginseng, Rb1, Rc, Rd, Re, Rg1, addition Paris polyphylla, Dioscorea, Panax quinquefolius, Platycodon grandiflorus. Moreover, was found markedly elevate concentrations Notoginsenoside R1, Ginsenoside Rb2, along with Lancemasid Quinoa saponins. use both shown effectively increase R1 ginsenosides, encompassing Rg1. Overall, results suggest individual applications have positive impact enhancement promote content, prolonged may lead soil compaction acidification, which could compromise yield quality On other hand, improve environment stimulate accumulation, they do not supply all nutrients required for sustained growth these Therefore, balanced fertilization strategy combining recommended optimal approach cultivating saponin-rich

Metagenomic analysis revealed N-metabolizing microbial response of Iris tectorum to Cr stress after colonization by arbuscular mycorrhizal fungi

Ecotoxicology and Environmental Safety, Journal Year: 2024, Volume and Issue: 273, P. 116157 - 116157

Published: March 1, 2024

Arbuscular mycorrhizal fungi (AMF) and plant growth-promoting bacteria enhance tolerance to abiotic stress promote growth in contaminated soil. However, the interaction mechanism between rhizosphere microbial communities under chromium (Cr) remains unclear. This study conducted a greenhouse pot experiment metagenomics analysis reveal comprehensive effects of AMF (Rhizophagus intraradices) nitrogen-N metabolizing promoters on Iris tectorum. The results showed that significantly increased biomass nutrient levels I. tectorum soil decreased content Cr Metagenomics revealed structure composition community involved nitrogen metabolism changed after inoculation with stress. Functional genes related mineralization (gltB, gltD, gdhA, ureC, glnA), nitrate reduction ammonium (nirB, nrfA, nasA), assimilation (NRT, nrtA, nrtC) were up-regulated N-metabolizing community. In contrast, abundance functional denitrification (nirK narI) was down-regulated. addition, regulates synergies N-metabolic enhances complexity stability ecological network. provides basis for improving heavy metal by regulating through inoculation.

Can site-specific nutrient management improve the productivity and resource use efficiency of climate-resilient finger millet in calcareous soils in India?

Heliyon, Journal Year: 2024, Volume and Issue: 10(12), P. e32774 - e32774

Published: June 1, 2024

Finger millet, an important 'Nutri-Cereal' and climate-resilient crop, is cultivated as a marginal crop in calcareous soils. Calcareous soils have low organic carbon content, high pH levels, poor structure. Such situation leads to productivity of the crop. Site-specific nutrient management (SSNM), which focuses on supplying optimum nutrients when needed, can ensure production improve energy use efficiency crops. Moreover, developing appropriate SSNM technique for this could offer new insights into practices, particularly A field experiment was conducted during rainy seasons 2020 2021 soil at Dr. Rajendra Prasad Central Agricultural University, Pusa, India.

About How Nitrate Controls Nodulation: Will Soybean Spill the Bean?

Plant Cell & Environment, Journal Year: 2025, Volume and Issue: unknown

Published: Feb. 17, 2025

ABSTRACT Legumes have the beneficial capacity to establish symbiotic interactions with rhizobia, which provide their host plants fixed nitrogen. However, in presence of nitrogen, this process is rapidly repressed avoid unnecessary investments carbon symbiosis. Several players involved regulating nodulation response nitrate availability been identified, including peptide hormones, microRNAs and transcription factors. Nevertheless, how these molecular are linked each other what underlying mechanisms at play inhibit remain unresolved. Nitrate‐mediated control seems differ between model legumes, such as Medicago Lotus , compared legume crops soybean. A deeper understanding regulatory processes, particularly soybean, expected contribute establishing increased efficiency modern agricultural systems, hence improving sustainability by reducing need for environmentally hazardous nitrogen fertilizers. This review describes state art nitrate‐regulated while drawing parallels described legumes addressing knowledge gaps that require future study.

Long-term monoculture of Lycium barbarum significantly affects its productivity and soil health. Soil microbiota, which mediate the sustainable development ecosystems, are influenced by age wolfberry plants. However, comprehensive effects long-term cultivation L. on microbial community not yet fully understood. Here, we assessed stand diversity, composition, assembly, symbiotic networks bacterial fungal communities in root zone using high-throughput sequencing technology. The results showed that affected α-diversity communities, as evidenced tendency their Shannon Chao1 indices to increase then decrease. At same time, structure was tree age. Proteobacteria (28.77%–32.81%) always most dominant phylum, Ascomycetes (49.72%–55.82%) phylum. A number genus-level biomarkers were also identified soils associated with roots trees varying ages. Additionally, stochastic processes dominated assembly whereas balance between deterministic fluctuated complexity stability notably age, particularly from 10- 15-year-old trees. partial least squares path modeling (PLS-PM) analysis emphasized can indirectly regulate diversity network both influencing physicochemical properties. Furthermore, community, but exhibited direct strong regulation complexity. study offers valuable data for improving quality fruit yield under continuous cropping, has implications industry.
