Fragaria Iinumae
''Fragaria iinumae'' is a species of strawberry native to Japan and eastern Russia. In Japan it was first discovered on and the name was given. All strawberries have a base haploid count of 7 chromosomes. ''Fragaria iinumae'' is diploid, having 2 pairs of these chromosomes for a total of 14 chromosomes. ''Fragaria iinumae'' is one of the diploid progenitors of the octoploid strawberry.

Tomitarô Makino
200px, Tomitaro Makino was a pioneer Japanese botanist noted for his taxonomic work. He has been called "Father of Japanese Botany". He was one of the first Japanese botanists to work extensively on classifying Japanese plants using the system developed by Linnaeus. His research resulted in documenting 50,000 specimens, many of which are represented in his ''Makino's Illustrated Flora of Japan''. Despite having dropped out of grammar school, he eventually attained a Doctor of Science degree, and his birthday is remembered as ''Botany Day'' in Japan. Early life Tomitaro Makino was born in Sakawa, Kōchi to a prestigious sake brewer. His parents died during his early childhood, and he was raised mainly by his grandmother. Though he dropped out of school after two years, he cultivated a strong interest in English, geography, and especially in botany. In 1880, he became a teacher at the primary school in his hometown, where he published his first academic botanical paper. In ...

Fragaria
''Fragaria'' () is a genus of flowering plants in the rose family, Rosaceae, commonly known as strawberries for their edible fruits. There are more than 20 described species and many hybrids and cultivars. The most common strawberries grown commercially are cultivars of the garden strawberry, a hybrid known as ''Fragaria'' × ''ananassa''. Strawberries have a taste that varies by cultivar, and ranges from quite sweet to rather tart. Strawberries are an important commercial fruit crop, widely grown in all temperate regions of the world. Description Strawberries are not berries in the botanical sense.Esau, K. 1977. ''Anatomy of seed plants''. John Wiley and Sons, New York. The fleshy and edible part of the "fruit" is a receptacle, and the parts that are sometimes mistakenly called "seeds" are achenes and therefore the true botanical fruits. Etymology The genus name derives from ("strawberry") and , a suffix used to create feminine nouns and plant names. The Latin name is tho ...

Japan
Japan ( ja, 日本, or , and formally , ''Nihonkoku'') is an island country in East Asia. It is situated in the northwest Pacific Ocean, and is bordered on the west by the Sea of Japan, while extending from the Sea of Okhotsk in the north toward the East China Sea, Philippine Sea, and Taiwan in the south. Japan is a part of the Ring of Fire, and spans an archipelago of 6852 islands covering ; the five main islands are Hokkaido, Honshu (the "mainland"), Shikoku, Kyushu, and Okinawa. Tokyo is the nation's capital and largest city, followed by Yokohama, Osaka, Nagoya, Sapporo, Fukuoka, Kobe, and Kyoto. Japan is the eleventh most populous country in the world, as well as one of the most densely populated and urbanized. About three-fourths of the country's terrain is mountainous, concentrating its population of 123.2 million on narrow coastal plains. Japan is divided into 47 administrative prefectures and eight traditional regions. The Greater Tokyo Ar ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Russia
Russia (, , ), or the Russian Federation, is a transcontinental country spanning Eastern Europe and Northern Asia. It is the largest country in the world, with its internationally recognised territory covering , and encompassing one-eighth of Earth's inhabitable landmass. Russia extends across eleven time zones and shares land boundaries with fourteen countries, more than any other country but China. It is the world's ninth-most populous country and Europe's most populous country, with a population of 146 million people. The country's capital and largest city is Moscow, the largest city entirely within Europe. Saint Petersburg is Russia's cultural centre and second-largest city. Other major urban areas include Novosibirsk, Yekaterinburg, Nizhny Novgorod, and Kazan. The East Slavs emerged as a recognisable group in Europe between the 3rd and 8th centuries CE. Kievan Rus' arose as a state in the 9th century, and in 988, it adopted Orthodox Christianity from the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mount Nōgōhaku
is located on the borders of Gifu and Fukui prefectures in Japan. It is part of the Ryōhaku Mountains and serves as the drainage divide between the Pacific Ocean and the Japan Sea. There is one triangulation station at the top of the mountain. Fragaria iinumae was discovered at first in this Mountain and the name was given.

Haploid
Ploidy () is the number of complete sets of chromosomes in a cell (biology), cell, and hence the number of possible alleles for Autosome, autosomal and Pseudoautosomal region, pseudoautosomal genes. Sets of chromosomes refer to the number of maternal and paternal chromosome copies, respectively, in each homologous chromosome pair, which chromosomes naturally exist as. Somatic cells, Tissue (biology), tissues, and Individual#Biology, individual organisms can be described according to the number of sets of chromosomes present (the "ploidy level"): monoploid (1 set), diploid (2 sets), triploid (3 sets), tetraploid (4 sets), pentaploid (5 sets), hexaploid (6 sets), heptaploid or septaploid (7 sets), etc. The generic term polyploidy, polyploid is often used to describe cells with three or more chromosome sets. Virtually all sexual reproduction, sexually reproducing organisms are made up of somatic cells that are diploid or greater, but ploidy level may vary widely between different or ...

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 s ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Diploid
Ploidy () is the number of complete sets of chromosomes in a cell, and hence the number of possible alleles for autosomal and pseudoautosomal genes.

Virtually all sexually reproducing organisms are made up of somatic cells that are diploid or greater, but ploidy level may vary widely between different organisms, between different tissues within the same organism, and at different stages in an organism's life cycle. ...

Alpine Plant
Alpine plants are plants that grow in an alpine climate, which occurs at high elevation and above the tree line. There are many different plant species and taxa that grow as a plant community in these alpine tundra. These include perennial grasses, sedges, forbs, cushion plants, mosses, and lichens.. Alpine plants are adapted to the harsh conditions of the alpine environment, which include low temperatures, dryness, ultraviolet radiation, wind, drought, poor nutritional soil, and a short growing season. Some alpine plants serve as medicinal plants. Ecology Alpine plants occur in a tundra: a type of natural region or biome that does not contain trees. Alpine tundra occurs in mountains worldwide. It transitions to subalpine forests below the tree line; stunted forests occurring at the forest-tundra ecotone are known as ''Krummholz''. With increasing elevation, it ends at the snow line where snow and ice persist through summer, also known as the Nival Zone. Alpine plants are ...
