Article Abstract

One chromone (), together with four known alkaloids, were isolated from the mangrove endophytic fungus sp. ZJ-68. Their structures were elucidated by a combination of HRESIMS and NMR spectroscopic analyses. Compound showed strong anti-inflammatory activity by inhibiting nitric oxide (NO) production in lipopolysaccharide-activated RAW264.7 cells with an IC value of 4.094 ± 0.8 μM, which was better than positive drug indomethacin (IC=35.8 ± 0.5 μM).

Locoism refers to a neurological disorder in livestock caused by chronic ingestion of locoweeds, which contain toxic alkaloid swainsonine produced by the fungus . Therefore, reducing swainsonine levels not only prevents locoism but may also transform these toxic plants into animal feed. In this study, we identified a pivotal role for the gene in swainsonine biosynthesis.

Fungal endophytes and epiphytes associated with plant leaves can play important ecological roles through the production of specialized metabolites encoded by biosynthetic gene clusters (BGCs). However, their functional capacity, especially in crops like lettuce (Lactuca sativa L.), remains poorly understood.

Trichoderma species exhibit remarkable versatility in adaptability and in occupying habitats with lifestyles ranging from mycoparasitism and saprotrophy to endophytism. In this study, we present the first high-quality whole-genome assembly and annotation of T. lixii using Illumina HiSeq technology to explore the mechanisms of endophytic lifestyle and plant colonization.

Argemone mexicana is one of the known herbaceous plants hosting bioactive isoquinoline alkaloids. In the current study, an endophytic fungal isolate was studied for anti-inflammatory potential and the identification of its bioactive molecule. An endophytic fungus AMEF-14 was obtained from this plant and identified as Cladosporium ramotenellum based on microscopy and molecular tools.
