The Canadian Arctic Archipelago is a vast region of approximately 1,420,000 km(2), with a flora characterized by low species diversity, low endemicity, and little influence by alien species. New records of vascular plant species are documented here based on recent fieldwork on Victoria and Baffin Islands; additional records based on recent literature sources are mentioned. This paper serves as ...

Coastal wetlands are a type of unique ecosystem, in which rhizosphere microorganisms vegetation play significant role the overall ecology. Rhizosphere soil samples from Liaohekou Wetlands, Northeast China (40°54?44? N, 121°47?51? E), were collected seven habitats (Suaeda and Phragmites community different coverage, aquaculture ponds farmland biotopes) to evaluate diversity structure bacterial u...

H(+)-translocating inorganic pyrophosphatases (H(+)-PPase) were recognized as the original energy donors in the development of plants. A large number of researchers have shown that H(+)-PPase could be an early-originated protein that participated in many important biochemical and physiological processes. In this study we cloned 14 novel sequences from 7 eremophytes: Sophora alopecuroid (Sa), Gl...
