Natsudaidai
or is a yellowish orange citrus hybrid fruit, a group of cultivars of ''Citrus natsudaidai'', which were discovered in 1740 in the Yamaguchi prefecture of Japan. Names ''Amanatsu'' means "sweet summer" in Japanese. In Japan, the fruit is known as , but also colloquially the ''amanatsu'', , , and . Description Natsumikan is about the size of grapefruit and oblate in shape. The fruit contains 12 segments and about 30 seeds. The rough textured fruit is easy to peel and is commonly eaten fresh. It is also used for wide variety of products ranging from marmalades to alcoholic beverages. Cultivation Natsumikan is grown commercially in Japan, notably in Yamaguchi, Kumamoto and Ehime prefecture. The city of Hagi is famous for its natsumikans, particularly when used in natsumikan juice and ice cream. Yamaguchi Prefecture takes such pride in their natsumikan industry that the typically white crash barriers of Japan were changed to a befitting orange. Genetics The natsumika ...

Citrus Tristeza Virus
Citrus tristeza virus (CTV) is a viral species of the genus ''Closterovirus'' that causes the most economically damaging disease to its namesake plant genus, ''Citrus''. The disease has led to the death of millions of ''Citrus'' trees all over the world and has rendered millions of others useless for production. Farmers in Brazil and other South American countries gave it the name "tristeza", meaning sadness in Portuguese and Spanish, referring to the devastation produced by the disease in the 1930s. The virus is transmitted most efficiently by the brown citrus aphid. The pathogen CTV is a flexuous rod virus with dimensions of 2000 nm long and 12 nm in diameter. The CTV genome is typically between 19.2 and 19.3 kb long and consists of a single strand of (+)-sense RNA enclosed by two types of capsid proteins. The size of its genome makes CTV one of the largest RNA viruses known. The CTV genome contains 12 open reading frames, which could encode at least 17 proteins.U ...

Plantae
Plants are predominantly Photosynthesis, photosynthetic eukaryotes of the Kingdom (biology), kingdom Plantae. Historically, the plant kingdom encompassed all living things that were not animals, and included algae and fungi; however, all current definitions of Plantae exclude the fungi and some algae, as well as the prokaryotes (the archaea and bacteria). By one definition, plants form the clade Viridiplantae (Latin name for "green plants") which is sister of the Glaucophyte, Glaucophyta, and consists of the green algae and Embryophyte, Embryophyta (land plants). The latter includes the flowering plants, conifers and other gymnosperms, ferns and Fern ally, their allies, hornworts, liverworts, and mosses. Most plants are multicellular organisms. Green plants obtain most of their energy from sunlight via photosynthesis by primary chloroplasts that are derived from endosymbiosis with cyanobacteria. Their chloroplasts contain chlorophylls a and b, which gives them their green colo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Citrus Hybrids
Citrus taxonomy refers to the botanical classification of the species, varieties, cultivars, and graft hybrids within the genus ''Citrus'' and related genera, found in cultivation and in the wild. Citrus taxonomy is complex and controversial. Cultivated citrus are derived from various citrus species found in the wild. Some are only selections of the original wild types, many others are hybrids between two or more original species, and some are backcrossed hybrids between a hybrid and one of the hybrid's parent species. Citrus plants hybridize easily between species with completely different morphologies, and similar-looking citrus fruits may have quite different ancestries. Some differ only in disease resistance. Conversely, different-looking varieties may be nearly genetically identical, and differ only by a bud mutation. Detailed genomic analysis of wild and domesticated citrus cultivars has suggested that the progenitor of modern citrus species expanded out of the Himalaya ...

Citrus Variety Collection
The UCR Citrus Variety Collection (CVC) is one of the most important collections of citrus diversity in the world. It is used for research, plant breeding, and educational extension activities on the UC Riverside campus in Riverside, California. Holdings The collection is composed of over 1000 accessions, planted as two trees of each of various types of citrus and citrus relatives. The collection largely comprises accessions within the genus ''Citrus'', the remaining types are included among 28 other related genera in the Rutaceae subfamily Aurantiodeae. The collection consists of approximately on the UCR campus, at the South Coast Research and Extension Center in Irvine, California, and at the Coachella Valley Agricultural Research Station in Thermal, California. It includes accessions that were first introduced in the early 20th century, as well as varieties brought in over time from various curators, and newer varieties that were more recently developed by breeding or br ...

Mikan
''Citrus unshiu'' is a semi-seedless and easy-peeling citrus species, also known as miyagawa mandarin, unshu mikan, cold hardy mandarin, satsuma mandarin, satsuma orange, naartjie, and tangerine. ''Citrus unshiu'' was named after Unshu (Wenzhou), a famous production area of mandarin oranges in China, in the late Edo period of Japan. It is said to have originated in either Japan or China, and because of its name, it is often described as originating in China;The Satsuma Mandarin University of Florida "probable origin in Kyushu islands, Japan or imported from China to Japan." however, due to multiple genetic studies conducted in the 2010s, the theory that the maternal species ...

Japanese Citrus
A number of citrus fruits are grown in or strongly associated with Japan. Many of these fruits are of Chinese origin, but have been modified or specially bred for cultivation in Japan. Japanese taxonomy Japan usually follows the botanical names of the taxonomy from Tyôzaburô Tanaka, often referred to as the "Tanaka system", giving for each cultivar a separate name no matter if it is pure or a hybrid of two or more species or varieties. While elsewhere it is more popular to classify the genus citrus into species, and further into varieties, and then into cultivars or hybrid. Such a system was created by Walter Tennyson Swingle from Florida and is called the "Swingle system". The different approaches of the two systems lead to partially-overlapping or nested 'species', for example, ''Citrus unshiu'' and ''Citrus tangerina'' (Tanaka) versus ''Citrus reticulata'' (Swingle). Likewise, common terms, like "mikan", do not always align with these taxonomic groups. Japanese citrus (pa ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Daidai
The daidai (Japanese: 橙, 臭 橙; Chinese: 酸 橙; Korean: 광귤, ''gwanggyul''), is an Asian variety of bitter orange. The daidai originated in the Himalayas. It spread to the Yangtze valley region and later to Japan. The colour of the fruit loses yellowish hue and becomes greener in the spring. The native Japanese word for the color orange, or ''daidai-iro'', is derived from the name of this fruit. Uses There are two main cultivars, and , and the latter bears smaller fruits than the former in Japan. The fruit is very bitter, and not usually eaten, but its dried peel is used in Kampo (the Japanese adaptation of Chinese medicine). The dry peels of young fruits are called ''kijitsu'' ( 枳 実), and used as a stomachic and expectorant as well as a laxative. Peel of ripe daidai is called , and is used as a fragrant stomachic and expectorant. Cultural aspect The name ''daidai'', originally meaning "several generations" (and written as or ), came from the fruit staying ...

Dermatitis
Dermatitis is inflammation of the skin, typically characterized by itchiness, redness and a rash. In cases of short duration, there may be small blisters, while in long-term cases the skin may become thickened. The area of skin involved can vary from small to covering the entire body. Dermatitis is often called eczema, and the difference between those terms is not standardized. The exact cause of the condition is often unclear. Cases may involve a combination of allergy and poor venous return. The type of dermatitis is generally determined by the person's history and the location of the rash. For example, irritant dermatitis often occurs on the hands of those who frequently get them wet. Allergic contact dermatitis occurs upon exposure to an allergen, causing a hypersensitivity reaction in the skin. Prevention of atopic dermatitis is typically with essential fatty acids, and may be treated with moisturizers and steroid creams. The steroid creams should generally be of mid ...

Allergic
Allergies, also known as allergic diseases, refer a number of conditions caused by the hypersensitivity of the immune system to typically harmless substances in the environment. These diseases include hay fever, food allergies, atopic dermatitis, allergic asthma, and anaphylaxis. Symptoms may include red eyes, an itchy rash, sneezing, coughing, a runny nose, shortness of breath, or swelling. Note: food intolerances and food poisoning are separate conditions. Common allergens include pollen and certain foods. Metals and other substances may also cause such problems. Food, insect stings, and medications are common causes of severe reactions. Their development is due to both genetic and environmental factors. The underlying mechanism involves immunoglobulin E antibodies (IgE), part of the body's immune system, binding to an allergen and then to a receptor on mast cells or basophils where it triggers the release of inflammatory chemicals such as histamine.
