Nine polyketides, including two new benzophenone derivatives, peniphenone (1) and methyl peniphenone (2), along with seven known xanthones (3-9) were obtained from mangrove endophytic fungus Penicillium sp. ZJ-SY₂ isolated from the leaves of Sonneratia apetala. Their structures were elucidated on the basis of MS, 1D, and 2D NMR data. Compounds 1, 3, 5, and 7 showed potent immunosuppressive acti...

Two new secondary metabolites, endomeketals A-B (1-2), a new natural product (3), and a known compound (4) were isolated from the ethyl acetate extract of the endophytic fungus Endomelanconiopsis endophytica A326 derived from Ficus hirta. Their structures were determined on the basis of extensive spectroscopic analysis. All compounds were evaluated for their cytotoxic activities against SF-268,...

The aim of the present study was to isolate, identify and observe antibacterial activity of the endophytic fungi against some pathogenic bacteria as well as to optimize various parameters for maximum production of antibacterial bioactive compounds. Endophytic fungi were isolated from Menthe viridis collected from Khamariya, Jabalpur M.P. (India). Screening of endophytic fungi for in-vitro antib...

The common bean is the most important food legume in the world. We examined the potential of the fungal entomopathogens Beauveria bassiana and Metarhizium anisopliae applied as seed treatments for their endophytic establishment in the common bean. Endophytic colonization in sterile sand:peat averaged ca. 40% higher for fungus treatments and ca. six times higher for volunteer fungi (other fungal...

Halophilic fungi have evolved unique osmoadaptive strategies, enabling them to thrive in hypersaline habitats. Here, we conduct morphological and transcriptomic response of endophytic fungus (Aspergillus montevidensis ZYD4) in both the presence and absence of salt stress. Under salt stress, the colony morphology of the A. montevidensis ZYD4 changed drastically and exhibited decreased colony pig...

Most land plants are able to form symbiotic associations with fungi, and in many cases these associations are necessary for plant and fungal survival. These plant/fungal associations are formed with mycorrhizal (arbuscular mycorrhizal or ectomycorrhizal) or endophytic fungi, fungi from distinct phylogenetic lineages. While it has been shown that mycorrhizal fungi are able to transfer nutrients ...

1. Plants form mutualistic symbioses with a variety of microorganisms including endophytic fungi that live inside the plant and cause no overt symptoms of infection. Some endophytic fungi form defensive mutualisms based on the production of bioactive metabolites that protect the plant from herbivores in exchange for a protected niche and nutrition from the host plant. Key elements of these symb...

The endophytic fungus strain MRCJ-326, isolated from Allium schoenoprasum, which is also known as Snow Mountain Garlic or Kashmiri garlic, was identified as Penicillium pinophilum on the basis of morphological characteristics and internal transcribed spacer region nucleotide sequence analysis. The endophytic fungus extract was subjected to 2D-SEPBOX bioactivity-guided fractionation and purifica...

A tropical endophytic isolate of the fungus Fusarium verticillioides (synonym Fusarium moniliforme) obtained from Zea mays was co-transformed with plasmid pNH24 containing the Fusarium oxysporum nitrate reductase nia gene and plasmid pNOM 102 carrying the Escherichia coli β-glucuronidase gusA gene. Transformation frequency for the nia marker was 75 transformants μg vector DNA and introduction o...
