''Iris ivanovae'' is a plant species in the genus ''Iris'' and part of the subgenus ''Iris'' and in the section ''Pseudoregelia''. It is a rhizomatous perennial, from eastern Russia, China, and Mongolia. It has narrow and linear light green leaves, short slender stem and pink-purple flowers. It is cultivated as an ornamental plant in temperate regions. Description It is similar in form to ''Iris tigridia'' but differs in the leaves, being narrower on ''Iris tigridia'' and ''Iris ivanovae'' having smaller flowers. It has a thick, dark grey rhizome that is about 2 – 4 mm in diameter. Below the rhizome, it has wrinkled dark grey secondary roots.

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] |
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. Types of provincial level divisions Province The government of each standard province () is nominally led by a provincial committe ...

Trans-Baikal
Transbaikal, Trans-Baikal, Transbaikalia ( rus, Забайка́лье, r=Zabaykalye, p=zəbɐjˈkalʲjɪ), or Dauria (, ''Dauriya'') is a mountainous region to the east of or "beyond" (trans-) Lake Baikal in Far Eastern Russia. The steppe and wetland landscapes of Dauria are protected by the Daurian Nature Reserve, which forms part of a World Heritage Site named "The Landscapes of Dauria". Etymology The alternative name of the Transbaikal, ''Dauria'', derives from the ethnonym of the former inhabitants, the Daur people, whom Russian explorers first encountered in 1640. Geography Dauria stretches for almost 1,000 km from north to south from the Patom Plateau and North Baikal Plateau to the Russian state borders with Mongolia and China. The Transbaikal region covers more than 1,000 km from west to east from Lake Baikal to the meridian of the confluence of the Shilka and Argun Rivers. To the west and north lies the Irkutsk Oblast; to the north the Republic of Sakha ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Siberia
Siberia ( ; rus, Сибирь, r=Sibir', p=sʲɪˈbʲirʲ, a=Ru-Сибирь.ogg) is an extensive geographical region, constituting all of North Asia, from the Ural Mountains in the west to the Pacific Ocean in the east. It has been a part of Russia since the latter half of the 16th century, after the Russians conquered lands east of the Ural Mountains. Siberia is vast and sparsely populated, covering an area of over , but home to merely one-fifth of Russia's population. Novosibirsk, Krasnoyarsk and Omsk are the largest cities in the region. Because Siberia is a geographic and historic region and not a political entity, there is no single precise definition of its territorial borders. Traditionally, Siberia extends eastwards from the Ural Mountains to the Pacific Ocean, and includes most of the drainage basin of the Arctic Ocean. The river Yenisey divides Siberia into two parts, Western and Eastern. Siberia stretches southwards from the Arctic Ocean to the hills of north-ce ...

Native Plant
In biogeography, a native species is indigenous to a given region or ecosystem if its presence in that region is the result of only local natural evolution (though often popularised as "with no human intervention") during history. The term is equivalent to the concept of indigenous or autochthonous species. Every wild organism (as opposed to a domesticated organism) is known as an introduced species within the regions where it was anthropogenically introduced. If an introduced species causes substantial ecological, environmental, and/or economic damage, it may be regarded more specifically as an invasive species. The notion of nativity is often a blurred concept, as it is a function of both time and political boundaries. Over long periods of time, local conditions and migratory patterns are constantly changing as tectonic plates move, join, and split. Natural climate change (which is much slower than human-caused climate change) changes sea level, ice cover, temperature, and r ...

Agricultural Research Service
The Agricultural Research Service (ARS) is the principal in-house research agency of the United States Department of Agriculture (USDA). ARS is one of four agencies in USDA's Research, Education and Economics mission area. ARS is charged with extending the nation's scientific knowledge and solving agricultural problems through its four national program areas: nutrition, food safety and quality; animal production and protection; natural resources and sustainable agricultural systems; and crop production and protection. ARS research focuses on solving problems affecting Americans every day. The ARS Headquarters is located in the Jamie L. Whitten Building on Independence Avenue in Washington, D.C. and the headquarters staff is located at the George Washington Carver Center (GWCC) in Beltsville, Maryland. For 2018, its budget was $1.2 billion. Mission ARS conducts scientific research for the American public. Their main focus is on research to develop solutions to agricultural pr ...
