Chromosomes
A chromosome is a long DNA molecule with part or all of the genetic material of an organism. In most chromosomes the very long thin DNA fibers are coated with packaging proteins; in eukaryotic cells the most important of these proteins are the histones. These proteins, aided by chaperone proteins, bind to and condense the DNA molecule to maintain its integrity. These chromosomes display a complex three-dimensional structure, which plays a significant role in transcriptional regulation. Chromosomes are normally visible under a light microscope only during the metaphase of cell division (where all chromosomes are aligned in the center of the cell in their condensed form). Before this happens, each chromosome is duplicated (S phase), and both copies are joined by a centromere, resulting either in an X-shaped structure (pictured above), if the centromere is located equatorially, or a two-arm structure, if the centromere is located distally. The joined copies are now called sis ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Award Of Garden Merit
The Award of Garden Merit (AGM) is a long-established annual award for plants by the British Royal Horticultural Society (RHS). It is based on assessment of the plants' performance under UK growing conditions. History The Award of Garden Merit is a mark of quality awarded, since 1922, to garden plants (including trees, vegetables and decorative plants) by the United Kingdom, Royal Horticultural Society (RHS). Awards are made annually after plant trials intended to judge the plants' performance under UK growing conditions. Trials may last for one or more years, depending on the type of plant being analyzed, and may be performed at Royal Horticulture Society Garden in Wisley and other gardens or after observation of plants in specialist collections. Trial reports are made available as booklets and on the website. Awards are reviewed annually in case plants have become unavailable horticulturally, or have been superseded by better cultivars. Similar awards The award should not be ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Provinces Of China
The provincial level administrative divisions () are the highest-level administrative divisions of China. There are 34 such divisions claimed by the People's Republic of China, classified as 23 provinces (), five autonomous regions, four municipalities and two special administrative regions. The political status of Taiwan Province along with a small fraction of Fujian Province remain in dispute; those are under separate rule by the Republic of China, which is usually referred to as "Taiwan". Every province on Mainland China (including the island province of Hainan) has a Chinese Communist Party (CCP) provincial committee (), headed by a secretary (). The Committee Secretary is effectively in charge of the province, rather than the governor of the provincial government. The same arrangement exists for the autonomous regions and municipalities.

International Plant Names Index
The International Plant Names Index (IPNI) describes itself as "a database of the names and associated basic bibliographical details of seed plants, ferns and lycophytes." Coverage of plant names is best at the rank of species and genus. It includes basic bibliographical details associated with the names. Its goals include eliminating the need for repeated reference to primary sources for basic bibliographic information about plant names. The IPNI also maintains a list of standardized author abbreviations. These were initially based on Brummitt & Powell (1992), but new names and abbreviations are continually added. Description IPNI is the product of a collaboration between The Royal Botanic Gardens, Kew (Index Kewensis), The Harvard University Herbaria (Gray Herbarium Index), and the Australian National Herbarium ( APNI). The IPNI database is a collection of the names registered by the three cooperating institutions and they work towards standardizing the information. The stan ...

The Gardeners' Chronicle
''The Gardeners' Chronicle'' was a British horticulture periodical. It lasted as a title in its own right for nearly 150 years and is still extant as part of the magazine ''Horticulture Week''. History Founded in 1841 by the horticulturists Joseph Paxton, Charles Wentworth Dilke, John Lindley and the printer William Bradbury it originally took the form of a traditional newspaper, with both national and foreign news, but also with vast amounts of material sent in by gardeners and scientists, covering every conceivable aspect of gardening. Its first editor, John Lindley, was one of the founders. Another founder, Paxton, later also became editor. Prominent contributors included Charles Darwin and Joseph Hooker. By 1851, the circulation of ''The Gardeners' Chronicle'' was given as 6500. Compared with that of the far more eminent ''Observer'' at 6230, and ''The Economist'' at 3826, ''The Gardeners' Chronicle'' did astonishingly well. Possibly these figures include the Chronicle's lar ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
George Forrest (botanist)
George Forrest (13 March 1873 – 5 January 1932) was a Scottish botanist, who became one of the first western explorers of China's then remote southwestern province of Yunnan, generally regarded as the most biodiverse province in the country. Early life George Forrest was born in Falkirk, Scotland on 13 March 1873. He went to Kilmarnock Academy. After leaving school, he was apprenticed with a local chemist until 1891 when, on the inheritance of a small legacy, he then decided to travel to Australia,Charles Adams, Mike Early, Jane Brook and Katherine Bamford where he searched for gold and also worked on a sheep station before returning to Scotland in 1902. Forrest's life then took a most unexpected turn; caught in a shower while fishing the Gladhouse Loch in Tweedsdale, he sought shelter beneath an overhanging bank where he chanced upon an ancient stone coffin. The discovery led to his introduction to Professor Bayley Balfour, Regius Keeper of the Royal Botanic Garden, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
