The marine alga-derived fungus Coniothyrium cereale is a prolific producer of phenalenones. These polyketides were shown to possess antimicrobial effects and inhibitory activity towards the protease human leucocyte elastase (HLE). The current study focused on the biosynthesis of eight different structural types of phenalenones, comprising the natural products rousselianone A' (1), coniosclerodi...

Leaves from organic apple trees were dipped with different organic materials and leaves were placed on the orchard floor in autumn. Leaf area and the amount of ascospores of Venturia inaequalis were measured in spring. The objective of this research was to find alternatives for urea that simulate the decomposition of apple leaves and reduces the ascospore production. In both years urea gave an ...

Abstract Purpose Wheat sheath blight mainly infected by Rhizoctonia cerealis is one of the soil-borne fungal diseases wheat worldwide and prevalent in major growing areas China at present. This study aimed to evaluate antifungal activity 163 endophytic fungi on R. . Antifungal strains were identified their biosynthetic potential was analysed. Methods The evaluated via dual-culture antagonism as...

The new phenalenone metabolites 1, 2, 4, and 6 were isolated from the marine-derived endophytic fungus Coniothyrium cereale, in addition to the ergostane-type sterol (3) and entatrovenetinone (5). Compounds 1 and 2 represent two unusual nitrogen-containing compounds, which are composed of a sterol portion condensed via two bonds to phenalenone derivatives. Compound 6, which contains unprecedent...

To assess the impacts of Cu and Zn on fungi, we tested the growth of 18 taxonomically different saprotrophic (basidiomycete, ascomycete and zygomycete) fungi and their production of extracellular oxidative enzymes on Cu(0, 100, 200, 400 mg kg–1) or Zn(0, 100, 200, 400 mg kg–1) containing ABTS (2,2 ́-azino-bis(3-ethylbenzthiazoline-6-sulfonic acid) agar plates. Coniothyrium sp. was the most toler...

Coniothyrium minitans (synonym, Paraphaeosphaeria minitans) is a highly specific mycoparasite of the wide host range crop pathogen Sclerotinia sclerotiorum. The capability C. to destroy sclerotia S. sclerotiorum has been well recognized and it available as widely used biocontrol product Contans WG. We present draft genome sequence Conio (IMI 134523), which previously in extensive studies that f...

Three aviculariine genera endemic to Brazil are revised. Typhochlaena C. L. Koch, 1850 is resurrected, including five species; Pachistopelma Pocock, 1901 includes two species; and Iridopelma Pocock, 1901, six species. Nine species are newly described: Typhochlaena ammasp. n., Typhochlaena costaesp. n., Typhochlaena curumimsp. n., Typhochlaena paschoalisp. n., Pachistopelma bromelicolasp. n., Ir...
