Lecanorchis Tabugawaensis
''Lecanorchis tabugawaensis'' is a species of orchid which belongs to the group of mycoheterotrophic plants. Mycoheterotrophs are known for feeding off of the roots of fungal hosts, instead of utilizing photosynthesis. Myco-heterotrophy refers to the harmonious relationship between particular plants and fungi. After a thorough exploration of the plant's shape, size, and structure, it was determined to be closely associated with orchidaceous Lecanorchis amethystea, although inward variations confirmed this unique species. The plant was discovered in July 2015 by Yamashita Hiroaki in lowland forests on Yakushima island. This species is only found at two locations along the Tabu River. Other recent discoveries on this island include: ''Oxygyne yamashitae'' (2008), ''Gastrodia uraiensis'' (2015), and ''Sciaphila yakushimensis'' (2016). This island also harbors various scarce plant species such as ''Lecanorchis virella'', ''Lecanorchis trachycaula'', ''Yakushimense vexillabium'', '' ...

Myco-heterotrophy
Myco-heterotrophy (from Greek μύκης , "fungus", ἕτερος ', "another", "different" and τροφή ', "nutrition") is a symbiotic relationship between certain kinds of plants and fungi, in which the plant gets all or part of its food from parasitism upon fungi rather than from photosynthesis. A myco-heterotroph is the parasitic plant partner in this relationship. Myco-heterotrophy is considered a kind of cheating relationship and myco-heterotrophs are sometimes informally referred to as "mycorrhizal cheaters". This relationship is sometimes referred to as mycotrophy, though this term is also used for plants that engage in mutualistic mycorrhizal relationships. Relationship between myco-heterotrophs and host fungi Full (or obligate) myco-heterotrophy exists when a non-photosynthetic plant (a plant largely lacking in chlorophyll or otherwise lacking a functional photosystem) gets all of its food from the fungi that it parasitizes. Partial (or facultative) myco-heterotr ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Photosynthesis
Photosynthesis is a process used by plants and other organisms to convert light energy into chemical energy that, through cellular respiration, can later be released to fuel the organism's activities. Some of this chemical energy is stored in carbohydrate molecules, such as sugars and starches, which are synthesized from carbon dioxide and water – hence the name ''photosynthesis'', from the Greek ''phōs'' (), "light", and ''synthesis'' (), "putting together". Most plants, algae, and cyanobacteria perform photosynthesis; such organisms are called photoautotrophs. Photosynthesis is largely responsible for producing and maintaining the oxygen content of the Earth's atmosphere, and supplies most of the energy necessary for life on Earth. Although photosynthesis is performed differently by different species, the process always begins when energy from light is absorbed by proteins called reaction centers that contain green chlorophyll (and other colored) pigments/chromoph ...

Yakushima
is one of the Ōsumi Islands in Kagoshima Prefecture, Japan. The island, in area, has a population of 13,178. Access to the island is by hydrofoil ferry (7 or 8 times a day from Kagoshima, depending on the season), slow car ferry (once or twice a day from Kagoshima), or by air to Yakushima Airport (3 to 5 times daily from Kagoshima, once daily from Fukuoka and once daily from Osaka). Administratively, the whole island is the town of Yakushima. The town also serves neighbouring Kuchinoerabujima. The majority of the island is within the borders of the Kirishima-Yaku National Park. Yakushima's electricity is more than 50% hydroelectric, and surplus power has been used to produce hydrogen gas in an experiment by Kagoshima University. The island has been a test site for Honda's hydrogen fuel cell vehicle research. (There are no hydrogen cars stationed on the island but electric cars are run by the municipality.)
