Plant endophytic fungi are an important and novel resource of natural bioactive compounds with their potential applications in agriculture, medicine food industry. In the past two decades, many valuable antimicrobial, insecticidal, cytotoxic, anticancer activities have been successfully discovered from fungi. During long period co-evolution, a friendly relationship was formed between each endophyte its host plant. Some endophytes ability to produce same or similar as those originated plants....
Ustilaginoidea virens (Cooke) Takah is an ascomycetous fungus that causes rice false smut, a devastating emerging disease worldwide. Here we report 39.4 Mb draft genome sequence of U. encodes 8,426 predicted genes. The has ~25% repetitive sequences have been affected by repeat-induced point mutations. Evolutionarily, close to the entomopathogenic Metarhizium spp., suggesting potential host jumping across kingdoms. possesses reduced gene inventories for polysaccharide degradation, nutrient...
To examine in vivo a rodent model the potential role of AMP-activated protein kinase (AMPK) within ventromedial hypothalamus (VMH) glucose sensing during hypoglycemia.Using gene silencing technology to selectively downregulate AMPK VMH, key hypothalamic glucose-sensing region, we demonstrate for detection hypoglycemia. In hyperinsulinemic-hypoglycemic (50 mg dl(-1)) clamp studies were performed awake, chronically catheterized Sprague-Dawley rats that had been microinjected bilaterally VMH...
Three steroids and one nordammarane triterpenoid were isolated for the first time from endophytic fungus Pichia guilliermondii Ppf9 derived medicinal plant Paris polyphylla var. yunnanensis. By means of physicochemical spectrometric analysis, they identified as ergosta-5,7,22-trienol (1), 5α,8α-epidioxyergosta-6,22-dien-3β-ol (2), ergosta-7,22-dien-3β,5α,6β-triol (3), helvolic acid (4). Both micro-dilution-colorimetric spore germination assays employed to evaluate their antimicrobial...
Seven flavonoids have been isolated from the aerial parts of Halostachys caspica C. A. Mey. (Chenopodiaceae) for first time. By means physicochemical and spectrometric analysis, they were identified as luteolin (1), chrysin (2), 7-O-β-D-glucopyranoside (3), quercetin (4), 3-O-β-D-glucopyranoside (5), isorhamentin-3-O-β-D-glucopyranoside (6), isorhamentin-3-O-β-D-rutinoside (7). All evaluated to show a broad antimicrobial spectrum activity on microorganisms including seven bacterial one...
The screening for bioactive principles from several Chinese medicinal herbs showed that the essential oil of Cymbopogon distans aerial parts possessed strong repellency against booklouse, Liposcelis bostrychophila , and red flour beetle, Tribolium castaneum . A total 36 components were identified by GC GC-MS. trans-Geraniol (16.54%), (R)-citronellal (15.44%), (+)-citronellol (11.51%), α-elemol (9.06%) main followed β-eudesmol (5.71%) (+)-limonene (5.05%). From oil, four monoterpenes isolated...
During our screening program for agrochemicals from Chinese medicinal herbs and wild plants, the essential oil of Carum carvi fruits was found to possess strong contact toxicity against Sitophilus zeamais Tribolium castaneum adults, with LD50 values 3.07 3.29 mg/adult, respectively, also showed fumigant two grain storage insects LC50 3.37 2.53 mg/L, respectively. The obtained by hydrodistillation investigated GC GC-MS. main components were identified be (R)-carvone (37.98%) D-limonene...
In order to identify natural products for plant disease control, the essential oil of star anise (Illicium verum Hook. f.) fruit was investigated its antifungal activity on pathogenic fungi. The obtained by hydro-distillation analyzed chemical composition gas chromatography (GC) and chromatography-mass spectrometry (GC-MS). trans-Anethole (89.5%), 2-(1-cyclopentenyl)-furan (0.9%) cis-anethole (0.7%) were found be main components among 22 identified compounds, which accounted 94.6% total oil....
The aim of this research was to determine the chemical composition essential oil Acorus calamus rhizomes, its insecticidal activity against booklouse, (Liposcelis bostrychophila) and isolate any constituents from oil. A. rhizomes obtained by hydrodistillation analyzed GC-FID GC-MS. A total 32 components identified principal compounds in were determined be α-asarone (50.09%), (E)-methylisoeugenol (14.01%), methyleugenol (8.59%), followed β-asarone (3.51%), α-cedrene (3.09%) camphor (2.42%)....
Ustiloxins are a group of cyclopeptide mycotoxins produced by rice false smut pathogen Villosiclava virens (anamorph: Ustilaginoidea virens) which seriously threaten the safety production and health humans livestock. Ustiloxin A, accounting for 60% total ustiloxins, is main toxic component. Biotransformation, process modifying functional groups compounds means regio- or stereo-specific reactions catalyzed enzymes organisms, has been considered as an efficient way to detoxify mycotoxins. In...
Summary In order to learn how 1‐methylcyclopropene (1‐MCP) affects ripening and disease‐resistance of peach fruit ( Prunus persica L. cv. Jiubao) after harvest, they were treated with 1‐MCP some inoculated Penicillium expansum . Treating 0.2 μ L −1 at 22 °C for 24 h effectively slowed the decline in firmness. The minimal concentration able inhibit softening was 0.6 Changes other parameters related ripening, such as content soluble solids, total sugar, titratable acidity, pectin ethylene...
