Introduction: strain NQ8GII4 is an endophytic fungus with significant potential for improving growth and disease resistance of alfalfa. However, the molecular mechanisms underlying the symbiotic relationship between NQ8GII4 and alfalfa roots remain poorly understood.
Methods: In this study, we conducted (1) a comparative genomic analysis of selected saprophytic, pathogenic, and endophytic fungi, including molecular phylogeny analysis, whole-genome alignment, and divergence date estimation positioning, and (2) transcriptomic profiling of alfalfa roots infected with NQ8GII4.
A Cedrane and a Fusarin from the Algicolous Fungus Fusarium graminearum 12Ⅱ2N and Response to Mycoparasitism.

The fungal genus Fusarium is a treasure-trove of structurally diverse secondary metabolites, contributed greatly by marine-derived strains. A new cedrane sesquiterpene, fusacedrol (1), and a new fusarin member, fusarin M (2), were isolated from F. graminearum 12Ⅱ2N that was isolated as an endophyte from the marine brown alga Sargassum sp.

The ambrosia beetle Blandford (Coleoptera: Curculionidae: Scolytinae) has recently emerged as a pest in Chinese poplar plantations, causing significant economic losses through damage to host trees in association with its mutualistic fungus . This study evaluated the biocontrol potential of strain B-BB-1, strain B-SM-1, its metabolite prodigiosin, and two ectoparasitic mites, and . exhibited significant lethality toward adult female , reduced offspring production, and inhibited growth.

Deoxynivalenol (DON), fumonisin B (FB), and zearalenone (ZEN) are typical fusarium mycotoxins that occur worldwide in foodstuffs, posing significant health hazards to humans and animals. Single and combined exposure of DON, FB, and ZEN leads to intestinal toxicity but the toxicology mechanism research is still limited. In this study, we explored the cytotoxicity effects of DON, FB, ZEN, and their combination in rat intestinal epithelial cell line 6 (IEC-6) cells.

Three endophytic strains, Phomopsis sp., Fusarium proliferatum, and Tinctoporellus epimiltinus, isolated from various plants in the rainforest of the Philippines, were investigated regarding their ability to repress growth of the pathogenic fungus Colletotrichum musae on banana fruits causing anthracnose disease. An in vitro plate-to-plate assay and an in vivo sealed box assay were conducted, using commercial versus natural potato dextrose medium (PDA).
