Semisynthesis of the known Stemona alkaloids oxystemofoline (7) and methoxystemofoline (8) has been achieved starting from (11Z)-1',2'-didehydrostemofoline (6), which confirmed their structures and absolute configurations. The synthesis of (1'R)-hydroxystemofoline (9) helped establish this compound as a natural product from Stemona aphylla. (1'S)-Hydroxystemofoline (10) and a number of related ...

* Stable isotope abundance analyses recently revealed that some European green orchids and pyroloids (Ericaceae) are partially myco-heterotrophic, exploiting mycorrhizal fungi for organic carbon and nitrogen. Here we investigate related species to assess their nutritional mode across various forest and climate types in Germany and California. * C- and N-isotope signatures of five green pyroloid...

Rhizosphere soil microorganisms are significant factors affecting plant growth, especially that of saline–alkali tolerant plants in the desert ecosystem. We performed high-throughput sequencing order to identifying fungal community structures and their relationships physicochemical properties different layers for plant, Anabasis aphylla, its natural environment. The number unique operational ta...

Three known compounds, stemofoline (1), (2'S)-hydroxystemofoline (2), and (11Z)-1',2'-didehydrostemofoline (3), along with two new alkaloids, stemaphylline (4) and stemaphylline-N-oxide (5), have been isolated from a root extract of Stemona aphylla. The structures of these alkaloids were determined on the basis of their spectroscopic data. The analysis of the crude dichloromethane extract by GC...

Salt glands of Tamarix aphylla consist of three pairs of secretory cells arranged one upon the other. At the stage of secretion, the upper and middle pair of secretory cells develop in their walls an internal system of anastomosed rods, the protuberances. In the formation of the wall protuberances, Golgi vesicles and microtubules appear to participate. The stage of salt secretion is also charac...

A rare moss Buxbaumia aphylla was only recently found in Croatia. Here we report five new localities, one from Dilj Gora and four Mt. Papuk. Small populations on bare acidic soil within the forest along edges were registered.

An annotated list of mosses was compiled for the Teriberka area in tundra zone on Kola Peninsula (Barents Sea coast, Murmansk Region, North-West Russia). The study includes environs Teriberskaya Bay, lower reaches and Orlovka Rivers, village Dolgiy Brook valley. We used results our two expeditions, data from literature, moss specimens collected previous years by other researchers deposited KPAB...
