Streams draining agricultural basins are subjected to the input of fungicides which can affect aquatic microbial communities. We analyzed the effect of the fungicide tebuconazole (TBZ) on Alnus glutinosa and Populus nigra litter breakdown by aquatic microorganisms. For six weeks, fungal and

Flavan-3-ols including the monomeric catechin and the polymeric proanthocyanidins (PAs) are abundant phenolic metabolites in poplar (Populus spp.) previously described to protect leaves against pathogen infection. However, it is not known whether stems are also defended in this way. Here we

The effect of two stilbene compounds, pinosylvin and resveratrol, on the growth of several fungi was evaluated in plate tests. Wood decay tests were carried out with birch and aspen samples impregnated with the two stilbenes. In plate experiments, resveratrol had an enhancing effect on growth at

Herein, the class II hydrophobin gene HFBII-4 was cloned from the biocontrol agent Trichoderma asperellum ACCC30536 and recombinant rHFBII-4 was expressed in Pichia pastoris GS115. Treatment of Populus davidiana × P. alba var. pyramidalis (PdPap poplar) with rHFBII-4 altered the expression levels of

The transcription of TasMYB36 in the biocontrol species T. asperellum was upregulated in four different pathogenic fermentation broths, suggesting that TasMYB36 plays an important role in the response to biotic stresses. Seventy-nine MYB transcription factors that were homologous to TasMYB36 from

The tolerance of plants to biotic and abiotic stresses could be improved by transforming with fungal resistance-related genes. In this study, the cDNA sequence (GenBank Acc. No. KP337939) of the resistance-related gene Hsp24 encoding the 24 kD heat shock protein was obtained from the biocontrol

Eleven soil samples were collected from different plantations at the Forestry Model Base, Northeast Forestry University, China (45°43'10″N, 126°37'15″E), and 122 Trichoderma strains (T1-T122) were isolated. Nine Trichoderma species were identified based on morphological and molecular classification

BACKGROUND Populous euphratica tree which belongs to Salicaceae family is naturally distributed in many parts of the world. Our purpose was to compare the therapeutic effects of smoke of its burnt leaves with conventional cryotherapy in patients with warts. METHODS Sixty consecutive wart patients

UNASSIGNED : In previous in vitro bioassay studies, Populus balsamifera L. (Salicaceae), a medicinal plant ethnobotanically identified from the traditional pharmacopoeia of the Cree of Eeyou Istchee (Eastern James Bay area of Canada), exhibited a strong anti-obesity potential by potently inhibiting

The phytohormones jasmonate, gibberellin, salicylate, and ethylene regulate an interconnected reprogramming network integrating root development with plant responses against microbes. The establishment of mutualistic ectomycorrhizal symbiosis requires the suppression of plant defense responses

Populus tremula L. (Poplar), Fraxinus excelsior L. (ash) and Solidago virgaurea L. (goldenrod) have been used for medicinal purposes through centuries, to treat pain, fever and inflammation, but their mechanisms of action are still not fully understood. The present

Some pathogenesis-related proteins (PR proteins) are subject to positive selection, while others are under negative selection. Here, we report the patterns of molecular evolution in thaumatin-like protein (TLP, PR5 protein) genes of Populus trichocarpa. Signs of positive selection were found in 20

Drypetes klainei Pierre ex Pax is used in Cameroon by Baka people in the wound healing process and for the treatment of burns. In a previous paper we demonstrated the ability of both water (WE) and defatted methanol (DME) extracts to accelerate scratch wound closure in fibroblast cultures,

The effect of populin extract from black poplar (Populus nigra) on seven different late blight strains was tested under laboratory and field conditions. The growth rate of hyphae was found to be significantly lower in vitro after 3 and 4 v/v% populin applications. Stain M16 was
