Endophytic fungi (Fusarium mairei) culture broth (EFCB) was added to cell suspension cultures of Taxus cuspidata. After 5 days, cultures of T. cuspidata given 4 ml of EFCB produced a maximal yield of 6.11 mg/l paclitaxel, with a release ratio of 75%, 2- and 6.8-fold, respectively, greater than the controls. The active element in EFCB is an exopolysaccharide of approximately 79 kD. Endophytic fungi produced 0.19 mg/l of paclitaxel in its producing medium. However, when the supernatant of Taxus cell suspension cultures from day 20 was added to the paclitaxel-producing medium, the biomass of fungi decreased by 24% and the yield of paclitaxel by 45%. In a co-culture system of plant and fungus, the yield of paclitaxel (12.8 mg/l) was >2-fold higher than that in the EFCB-treatment system.

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.

Background And Aim: Synthetic dyes in the textile industry pose risks to human health and environmental safety. The current study aims to examine the efficacy of a novel esterase derived from an endophyte fungus in decolorizing diverse dyes, focusing on its production, purification, optimization, and characterization.
Results: Trichoderma afroharzianum AUMC16433, a novel fungal endophyte with esterase-producing ability, was first detected from the cladodes of Opuntia ficus indica by ITS-rRNA sequencing.

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.
