Gibberella zeae, a major cause of cereal scab, can be divided into two chemotypes based on production of the 8-ketotrichothecenes deoxynivalenol (DON) and nivalenol (NIV). We cloned and sequenced a Tri13 homolog from each chemotype. The Tri13 from a NIV chemotype strain (88-1) is located in the trichothecene gene cluster and carries an open reading frame similar to that of Fusarium sporotrichio...

A large number of Fusarium isolates was collected from blighted wheat spikes originating from 175 sampling sites, covering 15 provinces in China. Species and trichothecene chemotype determination by multilocus genotyping (MLGT) indicated that F. graminearum s. str. with the 15-acetyl deoxynivalenol (15ADON) chemotype and F. asiaticum with either the nivalenol (NIV) or the 3-acetyl deoxynivaleno...

Abstract. Benlembarek K, Lograda T, Ramdani M, Figueredo G, Chalard P. 2021. Chemical composition and antibacterial activities of Rhus tripartita essential oils from Algeria. Biodiversitas 22: 482-492. The yield in Algeria is low with an average 0.16 ± 0.017. chemical the was determined by GC-GC / MS analysis. Seventy-eight compounds were identified 92.3 26.4% total oil. α-pinene (58.72 14.45%)...

The aim of this study was to assess variations in aggressiveness and trichothecene production F. graminearum isolates originating from maize, wheat barley Serbia. Analyzing (98) obtained various agroecological conditions Serbia over the period 1993 2010, using HPLC method, following two chemotypes were observed: 3-acetyl-deoxinivalenol (3ADON) 15-acetyl-deoxinivalenol (15ADON). A great diversit...

Published: July 24, 2014 Figure 1. Schematic of the organization of Escherichia coli LPS. LPS was from the rough mutant J5 strain of E. coli O111:B4, which produces an Rc chemotype with a core oligosaccharide as described by MüllerLoennies et al. The original R mutants, which defined the different chemotypes were from Salmonella minnesota, so in this paper we use the terms Ra/Rc to denote the c...

We describe the structure-based design of a novel lead chemotype that binds to thumb pocket 2 of HCV NS5B polymerase and inhibits cell-based gt1 subgenomic reporter replicons at sub-micromolar concentrations (EC50<200nM). This new class of potent thumb pocket 2 inhibitors features a 1H-quinazolin-4-one scaffold derived from hybridization of a previously reported, low affinity thiazolone chemoty...

The genus Thymus (Lamiaceae) is represented by 38 species (64 taxa) in Turkey, and 24 of which are endemic to Turkey. Aerial parts of Thymus longicaulis subsp. chaubardii var. chaubardii, T. zygioides var. lycaonicus, T. longicaulis subsp. longicaulis var. subisophyllus and T. pulvinatus collected from three different localities in Balikesir province were subjected to hydrodistillation to yield...

Volatile oils from single plants of Thymus serpylloides ssp. gadorensis were collected from Southeastern Spain and studied to check for chemical variability using gas chromatography (GC) and gas chromatography-mass spectrometry (GC-MS). Many of the samples showed a phenolic chemotype, while another important group had significant levels of linalool. Geraniol, myrcene, caryophyllene oxide, terpi...

ferula communis l., subsp. communis, namely giant fennel, has extensively been used in traditional medicine for a wide range of ailments. fresh plant materials, crude extracts and isolated components of f. communis showed a wide spectrum of in vitro and in vivo pharmacological properties including antidiabetic, antimicrobial, antiproliferative, and cytotoxic activities. the present paper, revie...
