Alexander Von Bunge
Alexander Georg von Bunge (russian: Алекса́ндр Андре́евич Бу́нге; – ) was a Russian botanist. He is best remembered for scientific expeditions into Asia and especially Siberia. Early life and education Bunge was born under the name, Alexander Andreevič von Bunge on in Kyiv as second son of a family that belonged to the German minority in Tsarist Russia. HIs father, Andreas Theodor was a pharmacist who had emigrated from East Prussia to Russia with his grandfather in the 18th century and his mother, Elisabeth von Bunge, . They moved to Dorpat in 1815 after his father's death in 1814 and attended highschool from 1818 to 1821. He was educated at Dorpat and where he passed through the gymnasium during the period of 1821–1825. Then, he studied medicine and obtained his Doctorate of Medicine from University of Tartu on 1825. He also studied botany there under Carl Friedrich von Ledebour and completed his thesis entitled ''De relatione methodi pl ...

Bush Cherry
''Prunus'' sect. ''Microcerasus'' is a section of ''Prunus''. It used to be included in ''Prunus'' subg. ''Cerasus'', but phylogenetic research indicates it belongs to ''Prunus'' subg. ''Prunus''. It differs from ''Prunus'' subg. ''Cerasus'' by having three winter buds per axil. Species Species in this section are often called bush cherries or dwarf cherries. They include: * '' Prunus alaica'' * '' Prunus albicaulis'' * ''Prunus bifrons'' * ''Prunus brachypetala'' * '' Prunus chorossanica'' * '' Prunus dictyoneura'' * '' Prunus erythrocarpa'' * '' Prunus erzincanica'' * '' Prunus glandulosa'' * '' Prunus griffithii'' * '' Prunus hippophaeoides'' * ''Prunus humilis'' * '' Prunus incana'' * ''Prunus jacquemontii'' * ''Prunus japonica'' * '' Prunus microcarpa'' * ''Prunus pogonostyla'' * ''Prunus pojarkovii'' * ''Prunus prostrata'' * ''Prunus pseudoprostrata'' * ''Prunus pumila'' ** ''Prunus pumila'' var.

Chloroplast DNA
Chloroplast DNA (cpDNA) is the DNA located in chloroplasts, which are photosynthetic organelles located within the cells of some eukaryotic organisms. Chloroplasts, like other types of plastid, contain a genome separate from that in the cell nucleus. The existence of chloroplast DNA was identified biochemically in 1959, and confirmed by electron microscopy in 1962. The discoveries that the chloroplast contains ribosomes and performs protein synthesis revealed that the chloroplast is genetically semi-autonomous. The first complete chloroplast genome sequences were published in 1986, ''Nicotiana tabacum'' (tobacco) by Sugiura and colleagues and ''Marchantia polymorpha'' (liverwort) by Ozeki et al. Since then, a great number of chloroplast DNAs from various species have been sequenced. Molecular structure Chloroplast DNAs are circular, and are typically 120,000–170,000 base pairs long. They can have a contour length of around 30–60 micrometers, and have a mass of about 80� ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Prunus Dictyoneura
''Prunus dictyoneura'' () is a species of bush cherry found in Gansu, Hebei, Henan, Jiangsu, Ningxia, Shaanxi and Shanxi provinces of China. A shrub 0.3 to 1.0 (occasionally 2.0)m tall, it prefers to grow in thickets in grasslands on hillsides from 400 to 1600 (occasionally 2,300)m above sea level. Chloroplast DNA sequencing has shown that its closest relative is ''Prunus humilis ''Prunus humilis'' ( zh, 欧李) is a species of bush cherry native to northern China.

Description ''P. dictyoneura'' are shrubs at most 2m tall. The bark of branchlets is brownish gray, and young branchlets are pubescent. Winter buds are ovoid and densely downy. The stipules are linear, 3 to 4mm long, with margins gland-tipped and serrate. Petioles are 2 to 3 mm long and densely pubesc ...

Prunus
''Prunus'' is a genus of trees and shrubs, which includes (among many others) the fruits plums, cherries, peaches, nectarines, apricots, and almonds. Native to the North American temperate regions, the neotropics of South America, and the paleotropics of Asia and Africa, 430 different species are classified under ''Prunus''. Many members of the genus are widely cultivated for their fruit and for decorative purposes. ''Prunus'' fruit are drupes, or stone fruits. The fleshy mesocarp surrounding the endocarp is edible while the endocarp itself forms a hard, inedible shell called the pyrena ("stone" or "pit"). This shell encloses the seed (or "kernel") which is edible in many species (such as almonds) but poisonous in others (such as apricots). Besides being eaten off the hand, most ''Prunus'' fruit are also commonly used in processing, such as jam production, canning, drying, and seeds for roasting. Botany Members of the genus can be deciduous or evergreen. A few species ha ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Flora Of China
The flora of China consists of a diverse range of plant species including over 39,000 vascular plants, 27,000 species of fungi and 3000 species of bryophytes.Wu, Z. Y., P. H. Raven & D. Y. Hong, eds. 2006. Flora of China. Vol. 22 (Poaceae). Science Press, Beijing, and Missouri Botanical Garden Press, St. Louis More than 30,000 plant species are native to China, representing nearly one-eighth of the world's total plant species, including thousands found nowhere else on Earth. China's land, extending over 9.6 million km, contains a variety of ecosystems and climates for plants to grow in. Some of the main climates include shores, tropical and subtropical forests, deserts, elevated plateaus and mountains. The events of the continental drift and early Paleozoic Caledonian movement also play a part in creating climatic and geographical diversity resulting in high levels of endemic vascular flora. These landscapes provide different ecosystems and climates for plants to grow in, creati ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
