Abstract
Covering: up to December 2024Microbial metabolic pathways, including those of endophytic fungi, offer significant potential for synthesizing secondary metabolites, regardless of their ecological niche. 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.
期刊介绍：
Natural Product Reports (NPR) serves as a pivotal critical review journal propelling advancements in all facets of natural products research, encompassing isolation, structural and stereochemical determination, biosynthesis, biological activity, and synthesis.
With a broad scope, NPR extends its influence into the wider bioinorganic, bioorganic, and chemical biology communities. Covering areas such as enzymology, nucleic acids, genetics, chemical ecology, carbohydrates, primary and secondary metabolism, and analytical techniques, the journal provides insightful articles focusing on key developments shaping the field, rather than offering exhaustive overviews of all results.
NPR encourages authors to infuse their perspectives on developments, trends, and future directions, fostering a dynamic exchange of ideas within the natural products research community.
