J Microbiol Biotechnol 2025; 35:e2411051. [PMID: 40223278 PMCID: PMC12012612 DOI: 10.4014/jmb.2411.11051] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/20/2024] [Revised: 02/15/2025] [Accepted: 02/17/2025] [Indexed: 04/15/2025]
Abstract
The slow growth rate of medicinal plants has made them unable to meet people's needs, and the use of biotechnology to obtain natural products from medicinal plants can alleviate this problem. This study isolated and identified 42 endophytic fungi from the roots, stems, and leaves of Salvia miltiorrhiza, belonging to 13 genera. The endophytic fungi that promote the accumulation of secondary metabolites in the hairy roots of S. miltiorrhiza were screened by co-culture and elicitors preparation. Among them, 15 endophytic fungi presented relatively high crude polysaccharide yields. Co-culture experiments showed that endophytic strains had different effects on the biomass and the accumulation of secondary metabolites in the hairy roots of S. miltiorrhiza, with strain KLBMPSM237 being the most effective. The contents of tanshinone I, salvianolic acid B and rosmarinic acid in the hairy roots of S. miltiorrhiza were significantly increased by KLBMPSM237 polysaccharide inducers at different concentrations. This study provides new microbial resources and technical methods for increasing the natural products in hairy roots of S. miltiorrhiza.

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

Yang J, Zang W, Chen J, Lu D, Li R, Li C, Chen Y, Liu Q, Niu X. Genomic Analysis of Penicillium griseofulvum CF3 Reveals Potential for Plant Growth Promotion and Disease Resistance. J Fungi (Basel) 2025; 11:153. [PMID: 39997447 PMCID: PMC11856539 DOI: 10.3390/jof11020153] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/08/2025] [Revised: 02/12/2025] [Accepted: 02/14/2025] [Indexed: 02/26/2025] Open
Abstract
Penicillium griseofulvum CF3 is a fungus isolated from healthy strawberry soil, with the potential to promote the growth of plants and enhance their resistance to diseases. However, the genome sequence of P. griseofulvum CF3 remains unclear. Therefore, we performed the whole-genome CCS sequencing of P. griseofulvum CF3 using the PacBio Sequel II platform. The assembled genome comprised 104 contigs, with a total length of 37,564,657 bp, encoding 13,252 protein-coding genes. Comprehensive functional annotation was performed using various BLAST databases, including the non-redundant (Nr) protein sequence database, Gene Ontology (GO), the Kyoto Encyclopedia of Genes and Genomes (KEGG), EuKaryotic Orthologous Groups (KOG), and the Carbohydrate-Active enZymes (CAZy) database, to identify and predict protein-coding genes, tRNAs, and rRNAs. The Antibiotics and Secondary Metabolites Analysis Shell (Antismash) analysis identified 50 biosynthetic gene clusters involved in secondary metabolite production within the P. griseofulvum CF3 genome. The whole-genome sequencing of P. griseofulvum CF3 helps us to understand its potential mechanisms in promoting plant growth and enhancing disease resistance, paving the way for the application of the CF3 strain in sustainable crop production.

Efficient remediation of di-(2-ethylhexyl) phthalate and plant-growth promotion with the application of a phosphate-solubilizing compound microbial agent. THE SCIENCE OF THE TOTAL ENVIRONMENT 2024; 926:171904. [PMID: 38527548 DOI: 10.1016/j.scitotenv.2024.171904] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 01/09/2024] [Revised: 03/18/2024] [Accepted: 03/20/2024] [Indexed: 03/27/2024]
Abstract
The ecotoxic endocrine-disrupting chemical di-(2-ethylhexyl) phthalate (DEHP) is ubiquitous in agricultural soil, posing a serious threat to human health. Here, we report efficient soil-borne DEHP degradation and plant growth promotion by a microbial organic fertilizer GK-PPB prepared by combining a recycled garden waste-kitchen waste compost product with ternary compound microbial agent PPB-MA, composed of Penicillium oxalic MB08F, Pseudomonas simiae MB751, and Bacillus tequilensis MB05B. The combination of MB08F and MB751 provided synergistic phosphorus solubilization, and MB05B enhanced the DEHP degradation capacity of MB08F via bioemulsification. Under optimal conditions (25.70 °C and pH 7.62), PPB-MA achieved a 96.81 % degradation percentage for 1000 mg L-1 DEHP within 5 days. The degradation curve followed first-order kinetics with a half-life of 18.24 to 24.76 h. A complete mineralization pathway was constructed after identifying the degradation intermediates of 2H-labeled DEHP. Evaluation in Caenorhabditis elegans N2 showed that PPB-MA eliminated the ecological toxicity of DEHP. A pakchoi (Brassica chinensis L.) pot experiment demonstrated that GK-PPB promoted phosphorus solubilization and plant growth, reduced soil DEHP residue, and decreased DEHP accumulation in pakchoi, suggesting its potential practical utility in environmentally responsible and safe cultivation of vegetables.
