Yo Takenaka
Yo Takenaka (竹中 要 Takenaka Yō, 1903–1966) was a Japanese plant geneticist and a Professor of Department of Cell Genetics, National Institute of Genetics. He is notable for researching the phylogenetic classification of cherry blossom. He discovered that '' Prunus × yedoensis'' is a crossbreed of two wild species of Japanese cherry; ''Prunus spachiana'' forma ''ascendens'' (Edo higan) and ''Prunus speciosa'' (Oshima zakura) by crossing experiments. He was also known as a researcher on Japanese morning glory and Nicotiana. Career He was born in Hyōgo Prefecture, Japan in 1903. He graduated from the Department of Botany, Faculty of Science, Tokyo Imperial University in 1927. He was a Professor of Keijō Imperial University from 1929 to 1945. After the end of war, he became a Professor of National Institute of Genetics The National Institute of Genetics ("Japanese Institute of Genetics") is a Japanese institution founded in 1949.

Plant Genetics
Plant genetics is the study of genes, genetic variation, and heredity specifically in plants.Hartl D, Jones E (2005) It is generally considered a field of biology and botany, but intersects frequently with many other life sciences and is strongly linked with the study of information systems. Plant genetics is similar in many ways to animal genetics but differs in a few key areas. The discoverer of genetics was Gregor Mendel, a late 19th-century scientist and Augustinian friar. Mendel studied "trait inheritance", patterns in the way traits are handed down from parents to offspring. He observed that organisms (most famously pea plants) inherit traits by way of discrete "units of inheritance". This term, still used today, is a somewhat ambiguous definition of what is referred to as a gene. Much of Mendel's work with plants still forms the basis for modern plant genetics. Plants, like all known organisms, use DNA to pass on their traits. Animal genetics often focuses on parentage an ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Plant Geneticist
A plant geneticist is a scientist involved with the study of genetics in botany. Typical work is done with genes in order to isolate and then develop certain plant traits. Once a certain trait, such as plant height, fruit sweetness, or tolerance to cold, is found, a plant geneticist works to improve breeding methods to ensure that future plant generations possess the desired traits. Plant genetics played a key role in the modern-day theories of heredity, beginning with Gregor Mendel's study of pea plants in the 19th century. The occupation has since grown to encompass advancements in biotechnology that have led to greater understanding of plant breeding and hybridization. Commercially, plant geneticists are sometimes employed to develop methods of making produce more nutritious, or altering plant pigments to make the food more enticing to consumers.

Phylogenetic Nomenclature
Phylogenetic nomenclature is a method of nomenclature for taxa in biology that uses phylogenetic definitions for taxon names as explained below. This contrasts with the traditional approach, in which taxon names are defined by a '' type'', which can be a specimen or a taxon of lower rank, and a description in words. Phylogenetic nomenclature is currently regulated by the '' International Code of Phylogenetic Nomenclature'' (''PhyloCode''). Definitions Phylogenetic nomenclature ties names to clades, groups consisting of an ancestor and all its descendants. These groups can equivalently be called monophyletic. There are slightly different ways of specifying the ancestor, which are discussed below. Once the ancestor is specified, the meaning of the name is fixed: the ancestor and all organisms which are its descendants are included in the named taxon. Listing all these organisms (i.e. providing a full circumscription) requires the full phylogenetic tree to be known. In practice, ...

Cherry Blossom
A cherry blossom, also known as Japanese cherry or sakura, is a flower of many trees of Prunus, genus ''Prunus'' or Prunus subg. Cerasus, ''Prunus'' subg. ''Cerasus''. They are common species in East Asia, including China, Korea and especially in Japan. They generally refer to ornamental cherry trees, not to be confused with cherry tree, cherry trees that produce fruit for eating.Toshio Katsuki. (2015) ''Sakura''. pp.14–18 Iwanami Shoten. It is considered the national flower of Japan. Wild species of the cherry tree is widely distributed mainly in the Northern hemisphere. In the mainstream classification in Europe and North America, cherry trees for ornamental purposes are classified into the genus ''Prunus'' which consists of about 400 species. In the mainstream classification in Japan, China, and Russia, on the other hand, ornamental cherry trees are classified into the genus ''Cerasus'', which consists of about 100 species separated from the genus ''Prunus'', and the g ...

Prunus × Yedoensis
''Prunus'' × ''yedoensis'' (synonym ''Cerasus'' × ''yedoensis'') is a hybrid cherry tree between '' Prunus speciosa'' (''Oshima cherry'') as father plant and ''Prunus pendula'' f. ''ascendens'' (syn. ''Prunus itosakura'', ''Prunus subhirtella'' var. ''ascendens'', ''Edo higan'') as mother. It is a hybrid born in Japan and one of its cultivars, ''Prunus'' × ''yedoensis'' 'Somei-yoshino' or Yoshino cherry ( Japanese: 染井吉野 ソメイヨシノ ''Somei Yoshino''), is one of the most popular and widely planted cherry cultivars in temperate regions around the world today.Huxley, A., ed. (1992). ''New RHS Dictionary of Gardening''. Macmillan .Rushforth, K. (1999). ''Trees of Britain and Europe''. Collins . 'Somei-yoshino' is a clone from a single tree, and has been propagated by grafting all over the world.

Keijō Imperial University
, colloquially referred to as , was an Imperial University of Japan that existed between 1924 and 1946. This university was established in 1924 in Gyeongseong, known as Keijō during the period of Japanese occupation of Korea, now modern-day Seoul, South Korea. Keijō Imperial University was abolished by the United States Army Military Government in Korea (USAMGIK) in 1946, following the Japanese surrender to the Allies and the subsequent withdrawal of Japan from its occupation of Korea at the end of World War II.
