East African Highland Bananas
Matoke, locally also known as matooke, amatooke in Buganda (Central Uganda), ekitookye in southwestern Uganda, ekitooke in western Uganda, kamatore in Lugisu (Eastern Uganda), ebitooke in northwestern Tanzania, igitoki in Rwanda, Burundi and by the cultivar name East African Highland banana, is a starchy triploid banana cultivar originating from the African Great Lakes. The fruit is harvested green, carefully peeled, and then cooked and often mashed or pounded into a meal. In Uganda and Rwanda, the fruit is steam-cooked, and the mashed meal is considered a national dish in both countries. Matoke bananas are a staple food crop in Uganda, Kenya, Tanzania and other Great Lakes countries. They are also known as the Mutika/Lujugira subgroup. The medium-sized green fruits, which are of a specific group of banana, the East African Highland bananas (''Musa'' AAA-EA), are known in the Bantu languages of Uganda and Western Kenya as ''matoke''. Cooking bananas have long been and still ...

Musa Acuminata
''Musa acuminata'' is a species of banana native to South Asia, Southern Asia, its range comprising the Indian Subcontinent and Southeast Asia. Many of the modern edible dessert bananas are from this species, although some are hybrids with ''Musa balbisiana''. First cultivated by humans around 10 Year#Abbreviations yr and ya, kya (8000 BCE), it is one of the early examples of List of domesticated plants, domesticated plants. Description ''Musa acuminata'' is an evergreen perennial, not a tree. The trunk (known as the pseudostem) is made of tightly packed layers of leaf sheaths emerging from completely or partially buried corms. The leaves are at the top of the leaf sheaths, or Petiole (botany), petioles and in the subspecies M. a. truncata the blade or Lamina (leaf), lamina is up to22 feet (seven meters) in length and 39 inches (one meter) wide. The inflorescence grows horizontally or obliquely from the trunk. The individual flowers are white to yellowish-white in color and a ...

Pseudostem
A stem is one of two main structural axes of a vascular plant, the other being the root. It supports leaves, flowers and fruits, transports water and dissolved substances between the roots and the shoots in the xylem and phloem, stores nutrients, and produces new living tissue. The stem can also be called halm or haulm. The stem is normally divided into nodes and internodes: * The nodes hold one or more leaves, as well as buds which can grow into branches (with leaves, conifer cones, or flowers). Adventitious roots may also be produced from the nodes. * The internodes distance one node from another. The term "shoots" is often confused with "stems"; "shoots" generally refers to new fresh plant growth including both stems and other structures like leaves or flowers. In most plants stems are located above the soil surface but some plants have underground stems. Stems have four main functions which are: * Support for and the elevation of leaves, flowers, and fruits. The stems ke ...

Mutation
In biology, a mutation is an alteration in the nucleic acid sequence of the genome of an organism, virus, or extrachromosomal DNA. Viral genomes contain either DNA or RNA. Mutations result from errors during DNA or viral replication, mitosis, or meiosis or other types of damage to DNA (such as pyrimidine dimers caused by exposure to ultraviolet radiation), which then may undergo error-prone repair (especially microhomology-mediated end joining), cause an error during other forms of repair, or cause an error during replication (translesion synthesis). Mutations may also result from insertion or deletion of segments of DNA due to mobile genetic elements. Mutations may or may not produce detectable changes in the observable characteristics (phenotype) of an organism. Mutations play a part in both normal and abnormal biological processes including: evolution, cancer, and the development of the immune system, including junctional diversity. Mutation is the ultimate source o ...

Banana Beer
Banana beer is an alcoholic beverage made from fermentation of mashed bananas. Sorghum, millet or maize flour are added as a source of wild yeast. Etymology In Uganda, banana beer is known as ''mubisi'', in DR Congo as Kasiksi, in Kenya as ''urwaga'', and in Rwanda and Burundi as ''urwagwa''. Background Banana beer is sometimes consumed during rituals and ceremonies. A similar product called '' mwenge bigere'' is made in Uganda with only bananas and sorghum.Handbook of Indigenous Fermented Foods, 2nd edition 1995 It can also be found under the names ''kasiksi'', ''nokrars'', ''rwabitoke'', ''urwedensiya'', ''urwarimu'' and ''milinda kaki''. Production Banana beer is made from ripe (but not over-ripe) East African Highland bananas (''Musa acuminata'' Colla (AAA-EA), ''Mbidde'' clone set). To accelerate the ripening of bananas, a hole is dug in the ground, lined with dried banana leaves which are then set on fire. Fresh banana leaves are laid on top of them, and then the unrip ...

Species
In biology, a species is the basic unit of classification and a taxonomic rank of an organism, as well as a unit of biodiversity. A species is often defined as the largest group of organisms in which any two individuals of the appropriate sexes or mating types can produce fertile offspring, typically by sexual reproduction. Other ways of defining species include their karyotype, DNA sequence, morphology, behaviour or ecological niche. In addition, paleontologists use the concept of the chronospecies since fossil reproduction cannot be examined. The most recent rigorous estimate for the total number of species of eukaryotes is between 8 and 8.7 million. However, only about 14% of these had been described by 2011. All species (except viruses) are given a two-part name, a "binomial". The first part of a binomial is the genus to which the species belongs. The second part is called the specific name or the specific epithet (in botanical nomenclature, also sometimes i ...

Subspecies
In biological classification, subspecies is a rank below species, used for populations that live in different areas and vary in size, shape, or other physical characteristics (morphology), but that can successfully interbreed. Not all species have subspecies, but for those that do there must be at least two. Subspecies is abbreviated subsp. or ssp. and the singular and plural forms are the same ("the subspecies is" or "the subspecies are"). In zoology, under the International Code of Zoological Nomenclature, the subspecies is the only taxonomic rank below that of species that can receive a name. In botany and mycology, under the International Code of Nomenclature for algae, fungi, and plants, other infraspecific ranks, such as variety, may be named. In bacteriology and virology, under standard bacterial nomenclature and virus nomenclature, there are recommendations but not strict requirements for recognizing other important infraspecific ranks. A taxonomist decides whether ...

Synonym (taxonomy)
The Botanical and Zoological Codes of nomenclature treat the concept of synonymy differently. * In botanical nomenclature, a synonym is a scientific name that applies to a taxon that (now) goes by a different scientific name. For example, Linnaeus was the first to give a scientific name (under the currently used system of scientific nomenclature) to the Norway spruce, which he called ''Pinus abies''. This name is no longer in use, so it is now a synonym of the current scientific name, ''Picea abies''. * In zoology, moving a species from one genus to another results in a different binomen, but the name is considered an alternative combination rather than a synonym. The concept of synonymy in zoology is reserved for two names at the same rank that refers to a taxon at that rank - for example, the name ''Papilio prorsa'' Linnaeus, 1758 is a junior synonym of ''Papilio levana'' Linnaeus, 1758, being names for different seasonal forms of the species now referred to as ''Araschnia le ...

List Of Banana Cultivars
The following is a list of banana cultivars and the groups into which they are classified. Almost all modern cultivated varieties (cultivars) of edible bananas and plantains are hybrids and polyploids of two wild, seeded banana species, ''Musa acuminata'' and ''Musa balbisiana''. Cultivated bananas are almost always seedless (parthenocarpic) and hence sterile, so they are propagated vegetatively (cloned). They are classified into groups according to a genome-based system introduced by Ernest Cheesman, Norman Simmonds, and Ken Shepherd, which indicates the degree of genetic inheritance from the two wild parents and the number of chromosomes ( ploidy). Cultivars derived from ''Musa acuminata'' are more likely to be used as dessert bananas, while those derived from ''Musa balbisiana'' and hybrids of the two are usually plantains or cooking bananas. Classification of cultivars Banana plants were originally classified by Linnaeus into two species, which he called ''Musa paradisiac ...

Stigma (botany)
The stigma () is the receptive tip of a carpel, or of several fused carpels, in the gynoecium of a flower. Description The stigma, together with the style and ovary (typically called the stigma-style-ovary system) comprises the pistil, which is part of the gynoecium or female reproductive organ of a plant. The stigma itself forms the distal portion of the style, or stylodia, and is composed of , the cells of which are receptive to pollen. These may be restricted to the apex of the style or, especially in wind pollinated species, cover a wide surface. The stigma receives pollen and it is on the stigma that the pollen grain germinates. Often sticky, the stigma is adapted in various ways to catch and trap pollen with various hairs, flaps, or sculpturings. The pollen may be captured from the air (wind-borne pollen, anemophily), from visiting insects or other animals ( biotic pollination), or in rare cases from surrounding water (hydrophily). Stigma can vary from long and sle ...

Anther
The stamen (plural ''stamina'' or ''stamens'') is the pollen-producing reproductive organ of a flower. Collectively the stamens form the androecium., p. 10 Morphology and terminology A stamen typically consists of a stalk called the filament and an anther which contains ''microsporangia''. Most commonly anthers are two-lobed and are attached to the filament either at the base or in the middle area of the anther. The sterile tissue between the lobes is called the connective, an extension of the filament containing conducting strands. It can be seen as an extension on the dorsal side of the anther. A pollen grain develops from a microspore in the microsporangium and contains the male gametophyte. The stamens in a flower are collectively called the androecium. The androecium can consist of as few as one-half stamen (i.e. a single locule) as in '' Canna'' species or as many as 3,482 stamens which have been counted in the saguaro (''Carnegiea gigantea''). The androecium in var ...

Tepal
A tepal is one of the outer parts of a flower (collectively the perianth). The term is used when these parts cannot easily be classified as either sepals or petals. This may be because the parts of the perianth are undifferentiated (i.e. of very similar appearance), as in ''Magnolia'', or because, although it is possible to distinguish an outer whorl of sepals from an inner whorl of petals, the sepals and petals have similar appearance to one another (as in ''Lilium''). The term was first proposed by Augustin Pyramus de Candolle in 1827 and was constructed by analogy with the terms "petal" and "sepal". (De Candolle used the term ''perigonium'' or ''perigone'' for the tepals collectively; today, this term is used as a synonym for ''perianth''.) p. 39. Origin Undifferentiated tepals are believed to be the ancestral condition in flowering plants. For example, '' Amborella'', which is thought to have separated earliest in the evolution of flowering plants, has flowers with undiffer ...
