Conditions for efficient transformation of Amycolatopsis orientalis (Nocardia orientalis) protoplasts by Streptomyces plasmid cloning vectors were identified. Three streptomycete plasmid origins of replication function in A. orientalis, as do the apramycin resistance gene from Escherichia coli, the thiostrepton resistance gene from Streptomyces azureus, and the tyrosinase gene from Streptomyces...

Abstract Temple trees, including the gymnosperm Platycladus orientalis and angiosperm Styphnolobium japonicum , have been planted in China for thousands of years. Tree age thus varies widely from young to ancient trees. Foliar endophytes P. S. were surveyed this exploratory study that was based on isolation into culture sequencing fungi trees varying 10 5000 years ( ) 1700 ). Sequenced belonged...

Abstract Background Biogenic volatile organic compounds (BVOCs) play an essential role in tropospheric atmospheric chemical reactions. There are few studies conducted on BVOCs emission of dominant forest species the Jing-Jin-Ji area China. Based field survey, resources data and measured standard factors, Guenther model developed 1993 (G93) was applied this paper to estimate from several ( Platy...

In this study, soil obtained from a reclaimed coal gob pile was expected to be rapidly improved with the use of artificial vegetation restoration practices, such as forests, which increase taxonomic variety in microbial community and its functions. order successfully identify effect forest project on soil’s quality, field study conducted loess hilly area located Shanxi assess effects five commo...

China possesses large areas of plantation forests which take up great quantities of carbon. However, studies on soil respiration in these plantation forests are rather scarce and their soil carbon flux remains an uncertainty. In this study, we used an automatic chamber system to measure soil surface flux of a 50-year-old mature plantation of Platycladus orientalis at Jiufeng Mountain, Beijing, ...

Amblyseius orientalis (Ehara) (Acari: Phytoseiidae) is a native predatory mite species in China. It used to be considered as a specialist predator of spider mites. However, recent studies show it also preys on other small arthropod pests, such as Bemisia tabaci (Gennadius) (Hemiptera: Aleyrodidae). Experiments were conducted to investigate (1) prey preference of A. orientalis between Tetranychu...

Thuja orientalis L. [= Biota orientalis (L.) Endl., Platycladus orientalis (L.) Franco] (Cupressaceae) is an evergreen arbor widely distributed throughout Korea and China. This plant has been used in the traditional medicine for the treatment of hemorrhoids and hypertension. Previous chemical investigations on this plant reported the isolation of terpenoids, flavonoids and lignans. The extract ...
