These pathways can be modulated at the molecular level through genome and epigenome manipulation. The metabolic activation of fungal endophytes using epigenetics presents an exciting frontier in science, paving the way for advanced biotechnological applications and enhancing our understanding of these microorganisms' roles in ecosystems. This review examines the significant role of epigenetics in the biosynthesis of secondary metabolites from fungal endophytes, which is vital for drug discovery. Our primary focus centers on studies that explore the epigenetic modulation of endophytic fungi up until December 2024. Acknowledging the rapidly evolving landscape of epigenetic research in this field, which has limited examples for endophytic fungi, we provide crucial foundational insights into fungal epigenetics and relate these insights to the broader context of plant-microbe interactions and endophytic fungal epigenetics, supported by relevant examples. Key mechanisms, such as histone acetylation, histone methylation, and DNA methylation, are discussed alongside recent advances in small-molecule epigenetic modulators that can activate silent biosynthetic gene clusters (BGCs). Further, chromatin-dependent regulation of these BGCs and methods for probing chromatin modifications and secondary metabolism in fungi are discussed. The role of CRISPR-Cas9 genome editing, combined with epigenetic strategies, is highlighted, showcasing its ability to alter the metabolite profiles of fungal endophytes. Finally, we explore how artificial intelligence (AI), machine learning (ML), and deep learning (DL) innovations are transforming research in chemical epigenomics at the plant-microbe interface.</p>","PeriodicalId":94,"journal":{"name":"Natural Product Reports","volume":" ","pages":""},"PeriodicalIF":10.6,"publicationDate":"2025-07-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144726137","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Herein, we summarize the key methodological advancements in 1D and 2D NMR techniques in the past two decades, especially for the invention of computational technologies and/or introduction of artificial intelligence for automated data processing, which significantly strengthen the ability of NMR-based metabolomics to analyze crude microbial extracts. Preliminary fractionation is advocated to deconvolute samples and thus enhance detection sensitivity towards minor components overshadowed by a complex matrix. Particularly, the synergistic application of NMR-based metabolomics and genomics provides an expedient approach to correlate biosynthetic gene clusters with cognate metabolites, greatly improving the efficiency of dereplication and, thus, targeted discovery of novel compounds.

The pursuit of therapeutic drug targets has resulted in the discovery of potential modulators showing promise for the development of new drug candidates. Many of these modulators have been derived from natural products, employing diverse methods such as traditional medical knowledge, high-throughput screening, and bioinformatics approaches. Based on these discoveries, a variety of synthetic analogues have been developed to improve pharmacological profiles, target selectivity, and drug-like properties. Structural optimization of natural product scaffolds, including derivatization, bioisostere incorporation, and prodrug strategies, has enabled the rational design of potent inhibitors targeting amino acid metabolism. These efforts have expanded the utility of naturally occurring inhibitors, offering enhanced efficacy and therapeutic potential.

These interfaces support rational investigations into substrate specificity, module compatibility, and pathway derivatization as well as general enzyme clustering applications beyond PKS and NRPS systems. Synthetic interfaces can be integrated with computational tools to support a more systematic and scalable framework for modular enzyme engineering by providing predictive insights into domain compatibility and interface design.
