Bacteria harbored in/on the hyphae of the dark septate endophyte, Veronaeopsis simplex Y34, were identified as a single Rhizobium species by molecular analyses of bacterial 16S rRNA genes, and were successfully isolated from the endophyte. The Rhizobium-cured fungus was prepared thoroughly by an antibiotic treatment, thereby allowing an examination of their effects on organic substrate utilizat...
Three novel indolosesquiterpenes, xiamycin B (1b), indosespene (2), and sespenine (3), along with the known xiamycin A (1a) were isolated from the culture broth of Streptomyces sp. HKI0595, a bacterial endophyte of the widespread mangrove tree Kandelia candel. Agar diffusion assays revealed moderate to strong antimicrobial activities against several bacteria, including methicillin-resistant Sta...
the cypress family, cupressaceae, has a global dispersion. currently, endophytic microorganisms from plants are being investigated for their diversity and bioactivities. here, we aimed at exploration and characterization of cultivable endophytic fungi from foliar tissues of cupressaceae, i.e. cupressus arizonica, c. sempervirens var. cereiformis, c. sempervirens var. fastigiata, juniperus excel...
on tall fescue pastures (West et al., 1988; Clay, 1993; Siegel and Bush, 1996), as well as controlling plant disTall fescue (Festuca arundinacea Schreb.) is an important cooleases (Latch, 1997). A variety of alkaloids, N-containing season perennial forage naturally infected with an endophyte, Neotyphodium coenophialum Glenn, Bacon, & Hanlin, which produces ring structures, are produced in the t...
Many grasses have mutualistic symbioses with fungi of the family Clavicipitaceae. Tall fescue can harbor the obligate endophyte, Neotyphodium coenophialum that is asexually propagated and transmitted via host seeds. Total RNA was isolated from pseudostems of known endophyte-infected (E+) and endophyte-free (E-) plants and tested in triplicate on the Affymetrix Wheat Genome Array GeneChip and Ba...
Sixty-four growing steers were used in a split-plot experiment, where the whole plot was pasture, and implants. Whole treatment 4 × 2 factorial with four levels of fescue (High Endophyte, Low Novel, or Endophyte Free) two legume (Legumes No Legumes). The included implant (No Implant, Synovex One Grass, Revalor-G, Ralgro). Data collected weights, hair coat scores, length, rectal temperature (ev...
Effects of grazing low-endophyte (Acremonium coenophialum Morgan-Jones and Gams, less than 1% infection) Johnstone (J) or high-endophyte (60% infection) Kentucky-31 (K) tall fescue (Festuca arundinacea Schreb.) on grazing behavior and voluntary intake were studied. Six Angus steers (average initial BW = 326 kg) grazed 1.21-ha plots of each forage cultivar (three steers per cultivar) in four 28-...
We consider the construction of inverted hybrid inflation models in which the vacuum energy during inflation is at the TeV scale, and the inflaton couples to the Higgs field. Such models are of interest in the context of some recently proposed models of electroweak baryogenesis. We demonstrate how constraints on these models arise from quantum corrections, and how selfconsistent examples may be...
