The response of nutrient cycle, microbial community abundance and metabolic function to nitrogen fertilizer in rhizosphere soil of Schneid seedlings.

Nitrogen (N) as an essential macronutrient affects the soil nutrient cycle, microbial community abundance, and metabolic function. However, the specific responses of microorganisms and metabolic functions in rhizosphere soil of Schneid seedlings to N addition remain unclear. In this study, four treatments (CK, N5, N10 and N15) were conducted, and the soil physicochemical properties, enzyme activities, microbial community abundances and diversities, metabolism, and gene expressions were investigated in rhizosphere soil of Schneid.

The Effect of Cyclosporin A on and the Possible Mechanisms Involved.

is one of the major pathogenic fungi causing postharvest grape decay. The development of antifungal agents is beneficial to reduce the loss of grapes during storage. The aim of this study was to investigate the antifungal mechanism of cyclosporin A (CsA).

Antifungal Mechanism of MTE-1, a Novel Oligosaccharide Ester, against .

is a pathogenic fungus that causes false smut disease in rice during the flowering stage through stamen filaments. Currently, there is a need to develop safe and effective antifungal agents for the control of this disease. In our preliminary experiments, we found that MTE-1, a new trisaccharide ester, exhibits significant inhibitory activity against .

Acuminatums E and F, two new cyclic lipopeptides from HU0053 and their antifungal activity.

Two new cyclic lipopeptides, acuminatums E () and F (), together with four known cyclic lipopeptides, acuminatums A-D (-) were isolated from the corn culture of endophytic HU0053. Their structures were elucidated by spectroscopic and advanced Marfey's amino acid analysis. All compounds were found to exhibit antifungal activities against .

Isolation and identification of flavonoids components from L.

Background: L. is rich in flavonoids which exhibit different bioactivities. In order to investigate the flavonoids components of L.

[Chemical constituents from Canarium pimela fruits].

Objective: To investigate the chemical constituents from Canarium pimela fruits.

Methods: Compounds were obtained after separation and purification by silica gel and Sephadex LH-20. The structures were identified on the basis of physico-chemical properties and spectrum data.

Evaluation of antioxidant activities of extracts from 19 Chinese edible flowers.

Extracts of 19 selected edible flowers were investigated for their free radical scavenging activity (FRSA), polyphenolic contents and flavonoid contents in the paper. The results showed the extracts of Paeonia suffruticosa Andr., Paeonia lactiflora Pall.

Effects of Ficus hirta Vahl. (Wuzhimaotao) extracts on growth inhibition of HeLa cells.

Ficus hirta Vahl. (Wuzhimaotao) is widely used as a folk medicine by Hakka people in southern China. In order to ascertain if any major fraction can be attributed to have pronounced anticancer effect, extracts of Wuzhimaotao on cytotoxic and apoptosis of HeLa cell lines were evaluated.
