Symbiosis between the fungal endophyte Epichloë coenophiala naturally found in cool season grass tall fescue (Lolium arundinacea (Schreb) Darbysh.) is thought to provide a competitive advantage over endophyte-free grasses when grown under nutrient-limited conditions. The mechanisms involved purported improvement phosphorus (P) uptake due infection are still not understood. present study tested ...

A new fungal endophyte, Scolecobasidium humicola, was identified as a common dark septate endophytic fungal (DSE) species under both natural and agricultural conditions. This fungus was found to grow endophylically in the roots of tomato seedlings. Light microscopy of cross-sections of colonized tomato roots showed that the intercellular, pigmented hyphae of the fungus were mostly limited to th...

The plant kingdom is colonized by a diverse array of endophytic bacteria which form non-pathogenic relationships with their hosts. When beneficial, such associations can stimulate plant growth, increase disease resistance, improve the plant’s ability to withstand environmental stresses (e.g. drought), or enhance N2 fixation. Crop sequences can favour the build-up of advantageous associations of...

The fungus Acremonium typhinum produces a novel endoprotease during symbiotic endophytic infection of the grass, Poa ampla. This protease is unusual because it is highly active in the presence of sodium dodecyl sulfate. The enzyme is a thiol-containing serine protease and is localized to a crude membrane fraction. Similar protease activity has been detected in endophyte-infected Poa autumnalis ...

Abstract Lophodermium piceae is the most common endophyte of Norway spruce ( Picea abies ) needles, and it probably occurs in total distribution area spruce. Its significance to host tree still largely unknown mainly because no methodology known for generating endophyte-free saplings nor inoculation intact needles with this fungus. We report here how a daily heat treatment at 40 °C 8 h eradicat...

Sixty-four growing steers were used in a split-plot experiment, where the whole plot was pasture, and implant level. Whole treatment 4 × 2 factorial with four levels of fescue (High Endophyte, Low Novel, or Endophyte Free) two legume (Legumes No Legumes). The included (No Implant, Synovex One Grass, Revalor-G, Ralgro). Data collected weights, hair coat scores, length, rectal temperature (every ...

Fungal symbionts that colonize leaf tissue asymptomatically (endophytes) can alter the foraging behaviour of leaf-cutting ants, and decrease the productivity of this herbivore’s mutualistic fungal cultivar, Leucocoprinus gongylophorus. This negative effect of endophytes on the ant’s cultivar could be the result of direct fungalefungal interaction or indirect reductions in the quality of leaves,...

The presence of an endophytic fungus, Acremonium coenophialum, in tall fescue (Festuca arundinacea) deterred aphid feeding by Rhopalosiphum padi and Schizaphis graminum. Both species of aphid were unable to survive when confined to endophyte-infected tall fescue plants. Feeding deterrents and toxic factors to R. padi and Oncopeltus fasciatus, large milkweed bug, were primarily associated with a...

The new species Trichoderma martiale was isolated as an endophyte from sapwood in trunks of Theobroma cacao (cacao, Malvaceae) in Brazil. Based on sequences of translation-elongation factor 1-alpha (tef1) and RNA polymerase II subunit (rpb2) T. martiale is a close relative of, and morphologically similar to, T. viride, but differs in the production of discrete pustules on corn meal-dextrose aga...
