Pseudonocardia Xishanensis
''Pseudonocardia xishanensis'' is a Gram-positive and non-motile bacterium from the genus of ''Pseudonocardia'' which has been isolated from the roots of the plant ''Artemisia annua'' from the Xishan Mountains in China China, officially the People's Republic of China (PRC), is a country in East Asia. It is the world's most populous country, with a population exceeding 1.4 billion, slightly ahead of India. China spans the equivalent of five time zones and ....

LPSN
List of Prokaryotic names with Standing in Nomenclature (LPSN) is an online database that maintains information on the naming and taxonomy of prokaryotes, following the taxonomy requirements and rulings of the International Code of Nomenclature of Prokaryotes The International Code of Nomenclature of Prokaryotes (ICNP) formerly the International Code of Nomenclature of Bacteria (ICNB) or Bacteriological Code (BC) governs the scientific names for Bacteria and Archaea.P. H. A. Sneath, 2003. A short hist .... The database was curated from 1997 to June 2013 by Jean P. Euzéby. From July 2013 to January 2020, LPSN was curated by Aidan C. Parte. In February 2020, a new version of LPSN was published as a service of the Leibniz Institute DSMZ, thereby also integrating the Prokaryotic Nomenclature Up-to-date service.

Gram-positive
In bacteriology, gram-positive bacteria are bacteria that give a positive result in the Gram stain test, which is traditionally used to quickly classify bacteria into two broad categories according to their type of cell wall. Gram-positive bacteria take up the crystal violet stain used in the test, and then appear to be purple-coloured when seen through an optical microscope. This is because the thick peptidoglycan layer in the bacterial cell wall retains the stain after it is washed away from the rest of the sample, in the decolorization stage of the test. Conversely, gram-negative bacteria cannot retain the violet stain after the decolorization step; alcohol used in this stage degrades the outer membrane of gram-negative cells, making the cell wall more porous and incapable of retaining the crystal violet stain. Their peptidoglycan layer is much thinner and sandwiched between an inner cell membrane and a bacterial outer membrane, causing them to take up the counterstain (saf ...

Pseudonocardia
''Pseudonocardia'' is the type genus of the bacteria family Pseudonocardiaceae. Members of this genus have been found living mutualistically on the cuticle of the leafcutter ants because the bacteria has antibiotic properties that protect the fungus grown by the ants. When they are grooming, their legs are passed over their mouth gland (metapleural gland) that produces the antibiotic and then their legs touch the fungi while they are walking around. The ants have metapleural glands that produce the antimicrobial components to eliminate the ''Escovopsis'' fungi. The bacteria may also be found in crypts on the propleural plate. ''Pseudonocardia'' is found to have antibiotic properties provided to the leaf-cutter ant to inhibit the growth of ''Escovopsis'', which is a black yeast that parasitizes the leaf-cutter ant. ''Pseudonocardia'' can be found in both aquatic (including marine) and terrestrial ecosystems. ''Pseudonocardia'' belongs to the phylum ''Actinobacteria.'' Most ''Actinob ...

Artemisia Annua
''Artemisia annua'', also known as sweet wormwood, sweet annie, sweet sagewort, annual mugwort or annual wormwood (), is a common type of wormwood native to temperate Asia, but naturalized in many countries including scattered parts of North America. An extract of ''A. annua'', called artemisinin (or artesunate), is a medication used to treat malaria. Discovery of artemisinin and its antimalarial properties by the Chinese scientist, Tu Youyou, led to award of the 2011 Lasker Prize and 2015 Nobel Prize in Physiology or Medicine. Description ''Artemisia annua'' belongs to the plant family of ''Asteraceae'' and is an annual short-day plant. Its stem is erect brownish or violet brown. The plant itself is hairless and naturally grows from 30 to 100 cm tall, although in cultivation it is possible for plants to reach a height of 200 cm. The leaves of ''A. annua'' have a length of 3–5 cm and are divided by deep cuts into two or three small leaflets. The intensive aro ...

Xishan Mountains
The Western Hills () are the hills and mountains in the western part of Beijing. Geography Being an extension of the Taihang mountain range from the Hebei Province, the Western Hills cover approximately 17% of the Beijing municipality, including most of the Mentougou and Fangshan Districts as well as parts of Changping, Haidian, and Shijingshan. The elevation of the Western Hills range is between 100 m to over 1900 m above sea level and is visible from the city on clear days. A mix of deciduous and coniferous forests and highland meadows cover much of the Western Hills. Mountain streams feed into the Yongding and Juma Rivers, which flow through the Western Hills to irrigate the plains of Beijing. Coal is mined in Fangshan and Mentougou Districts. Natural and historical points of interest include river gorges, and hot springs, as well as temples, historic homes, secluded retreats and ancient ruins. Also known as the Western Hills Scenic Area, the area has long been used ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
China
China, officially the People's Republic of China (PRC), is a country in East Asia. It is the world's most populous country, with a population exceeding 1.4 billion, slightly ahead of India. China spans the equivalent of five time zones and borders fourteen countries by land, the most of any country in the world, tied with Russia. Covering an area of approximately , it is the world's third largest country by total land area. The country consists of 22 provinces, five autonomous regions, four municipalities, and two Special Administrative Regions (Hong Kong and Macau). The national capital is Beijing, and the most populous city and financial center is Shanghai. Modern Chinese trace their origins to a cradle of civilization in the fertile basin of the Yellow River in the North China Plain. The semi-legendary Xia dynasty in the 21st century BCE and the well-attested Shang and Zhou dynasties developed a bureaucratic political system to serve hereditary monarchies, or dyna ...
