The life history of Puccinia striiformis remains a mystery because the alternate host has never been identified. Inoculation of grasses using aeciospores from naturally infected Berberis chinensis and B. koreana resulted in infection on Poa pratensis, producing uredinia typical of stripe rust caused by P. striiformis. Analyses using real-time polymerase chain reaction and DNA sequence confirmed...

The role of the interactions between endophytes and alien plants has been unclear yet in plant invasion. We used a completely germ-free culture system to quantify the plant growth-promoting (PGP) effects of endophytic bacteria Bacillus sp. on aseptic seedlings of Wedelia trilobata and of its native clonal congener W. chinensis. The endophytic bacteria did not affect the growth of W. chinensis, ...

The Livistona chinensis seed has been used for centuries to clinically treat various types of cancer. However, the precise mechanism of its anticancer activity remains to be elucidated. In the present study, we evaluated the efficacy of the ethanol extract of Livistona chinensis seed (EELC) against tumor growth using a hepatocellular carcinoma (HCC) mouse xenograft model and an HCC cell line, H...

BACKGROUND The growing popularity of Chinese herbal medicine in the United States has prompted large-scale import of raw herbs from Asia. Many of the Asian herbs have phylogenetically related North American species. We compared three phylogenetically related species, namely Coptis chinensis (Huanglian), Hydrastis canadensis and Coptis trifolia to show whether they can be substituted by one anot...

brassica chinensis l. is a popular vegetable, especially in asian dishes. for plant growing withinorganic fertilizer, cadmium (cd) has been one of the highest metal and health-risk factors included. thisresearch aimed to assess the bioaccumulation of cd by the plant and its genetic changes. the plant was grownin the soil supplemented by cd at 0, 15, 30, 60 and 120 mg/kg. the accumulations in th...

The Chinese beard eel (Cirrhimuraena chinensis Kaup) is an intertidal fish and a model organism for the study of impacts caused by topological fluctuations during the Pleistocene and current intricate hydrological conditions on fauna living in the coastal areas of China. In this study, we examined the phylogeographical pattern, population genetic profile and demographical history of C. chinensi...

PREMISE OF THE STUDY Thirty-one microsatellite markers were developed for Sinocalycanthus chinensis (Calycanthaceae), an endemic endangered species in China. METHODS AND RESULTS Twenty-one polymorphic and 10 monomorphic microsatellite markers of S. chinensis were developed using methods of biotin-streptavidin capture and capillary electrophoresis. The number of alleles per locus was one to 20...

Sand bedding material is frequently used in dairy operations to reduce the occurrence of mastitis and enhance cow comfort. One objective of this work was to determine if sand-based bedding also supported the microbiologically based suppression of an introduced bacterial pathogen. Bedding samples were collected in summer, fall, and winter from various locations within a dairy operation and teste...

The residue behavior of chlorpyrifos, which is one of the extensively used insecticides all around the world, in six vegetable crops was assessed under greenhouse conditions. Each of the vegetables was subjected to a foliar treatment with chlorpyrifos. Two analytical methods were developed using gas chromatography equipped with a micro-ECD detector (LOQ = 0.05 mg kg(-1)) and liquid chromatograp...

Flowers of the kiwifruit species Actinidia chinensis produce a mixture of sesquiterpenes derived from farnesyl diphosphate (FDP) and monoterpenes derived from geranyl diphosphate (GDP). The tertiary sesquiterpene alcohol (E)-nerolidol was the major emitted volatile detected by headspace analysis. Contrastingly, in solvent extracts of the flowers, unusually high amounts of (E,E)-farnesol were ob...
