Canavalia Munroi
''Canavalia'' is a genus of plants in the legume family (Fabaceae) that comprises approximately 48 to 50 species of tropical vines. Members of the genus are commonly known as jack-beans. The species of ''Canavalia'' endemic to the Hawaiian Islands were named ''āwikiwiki'' by the Native Hawaiians. The name translates to "the very quick one" and comes from the Hawaiian word for "fast". The genus name is derived from the Malabar word for the species, ''kavavali'', which means "forest climber." Uses Several species are valued legume crops, including common jack-bean ('' C. ensiformis''), sword bean ('' C. gladiata'') and '' C. cathartica''. At least the first makes a beneficial weed- and pathogen-suppressing living mulch. The common jack-bean is also a source of the lectin concanavalin A, which is used as a reagent in glycoprotein biochemistry and immunology. The jack-bean is also a common source of purified urease enzyme used in scientific research. The bay bean (''C ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Native Hawaiians
Native Hawaiians (also known as Indigenous Hawaiians, Kānaka Maoli, Aboriginal Hawaiians, First Hawaiians, or simply Hawaiians) ( haw, kānaka, , , and ), are the indigenous ethnic group of Polynesian people of the Hawaiian Islands. Hawaii was settled at least 800 years ago with the voyage of Polynesians from the Society Islands. The settlers gradually became detached from their original homeland and developed a distinct Hawaiian culture and identity in their new isolated home. That included the creation of new religious and cultural structures, mostly in response to the new living environment and the need for a structured belief system through which to pass on knowledge. Hence, the Hawaiian religion focuses on ways to live and relate to the land and instills a sense of communal living as well as a specialized spatial awareness. The Hawaiian Kingdom was formed in 1795, when Kamehameha the Great, of the independent island of Hawaiʻi, conquered the independent islands of Oʻ ...

Glycoprotein
Glycoproteins are proteins which contain oligosaccharide chains covalently attached to amino acid side-chains. The carbohydrate is attached to the protein in a cotranslational or posttranslational modification. This process is known as glycosylation. Secreted extracellular proteins are often glycosylated. In proteins that have segments extending extracellularly, the extracellular segments are also often glycosylated. Glycoproteins are also often important integral membrane proteins, where they play a role in cell–cell interactions. It is important to distinguish endoplasmic reticulum-based glycosylation of the secretory system from reversible cytosolic-nuclear glycosylation. Glycoproteins of the cytosol and nucleus can be modified through the reversible addition of a single GlcNAc residue that is considered reciprocal to phosphorylation and the functions of these are likely to be an additional regulatory mechanism that controls phosphorylation-based signalling. In contrast, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Reagent
In chemistry, a reagent ( ) or analytical reagent is a substance or compound added to a system to cause a chemical reaction, or test if one occurs. The terms ''reactant'' and ''reagent'' are often used interchangeably, but reactant specifies a substance ''consumed'' in the course of a chemical reaction. ''Solvents'', though involved in the reaction mechanism, are usually not called reactants. Similarly, ''catalysts'' are not consumed by the reaction, so they are not reactants. In biochemistry, especially in connection with enzyme-catalyzed reactions, the reactants are commonly called substrates. Definitions Organic chemistry In organic chemistry, the term "reagent" denotes a chemical ingredient (a compound or mixture, typically of inorganic or small organic molecules) introduced to cause the desired transformation of an organic substance. Examples include the Collins reagent, Fenton's reagent, and Grignard reagents. Analytical chemistry In analytical chemistry, a reagent ...

Concanavalin A
Concanavalin A (ConA) is a lectin (carbohydrate-binding protein) originally extracted from the jack-bean (''Canavalia ensiformis''). It is a member of the legume lectin family. It binds specifically to certain structures found in various sugars, glycoproteins, and glycolipids, mainly internal and nonreducing terminal α-D- mannosyl and α-D-glucosyl groups. Its physiological function in plants, however, is still unknown. ConA is a plant mitogen, and is known for its ability to stimulate mouse T-cell subsets giving rise to four functionally distinct T cell populations, including precursors to regulatory T cells; a subset of human suppressor T-cells is also sensitive to ConA. ConA was the first lectin to be available on a commercial basis, and is widely used in biology and biochemistry to characterize glycoproteins and other sugar-containing entities on the surface of various cells. It is also used to purify glycosylated macromolecules in lectin affinity chromatography, as well as t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Lectin
Lectins are carbohydrate-binding proteins that are highly specific for sugar groups that are part of other molecules, so cause agglutination of particular cells or precipitation of glycoconjugates and polysaccharides. Lectins have a role in recognition at the cellular and molecular level and play numerous roles in biological recognition phenomena involving cells, carbohydrates, and proteins. Lectins also mediate attachment and binding of bacteria, viruses, and fungi to their intended targets. Lectins are ubiquitous in nature and are found in many foods. Some foods, such as beans and grains, need to be cooked, fermented or sprouted to reduce lectin content. Some lectins are beneficial, such as CLEC11A, which promotes bone growth, while others may be powerful toxins such as ricin. Lectins may be disabled by specific mono- and oligosaccharides, which bind to ingested lectins from grains, legumes, nightshade plants, and dairy; binding can prevent their attachment to the carbohy ...

Living Mulch
In agriculture, a living mulch is a cover crop interplanted or undersown with a main crop, and intended to serve the purposes of a mulch, such as weed suppression and regulation of soil temperature. Living mulches grow for a long time with the main crops, whereas cover crops are incorporated into the soil or killed with herbicides. Other benefits of mulches are slowing the growth of weeds, and protecting soil from water and wind erosion. Some living mulches were found to increase populations of the natural enemies of crop pests.Hartwig N.L., H.. Ammon 2002 Cover crops and living mulches Weed Sci. 50: 688-699 Legumes used as living mulches also provide nitrogen fixation, reducing the need for fertilizer. Benefits When cover crops are turned over into the soil, they contribute nutrients to the main crop so that less chemical fertilizer is required.Brophy L. S., G. H. Heichel and M.P. Russelle. 1987 Nitrogen transfer from forage legumes to grass in a systematic planting de ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pathogen
In biology, a pathogen ( el, πάθος, "suffering", "passion" and , "producer of") in the oldest and broadest sense, is any organism or agent that can produce disease. A pathogen may also be referred to as an infectious agent, or simply a germ. The term ''pathogen'' came into use in the 1880s. Typically, the term ''pathogen'' is used to describe an ''infectious'' microorganism or agent, such as a virus, bacterium, protozoan, prion, viroid, or fungus. Small animals, such as helminths and insects, can also cause or transmit disease. However, these animals are usually referred to as parasites rather than pathogens. The scientific study of microscopic organisms, including microscopic pathogenic organisms, is called microbiology, while parasitology refers to the scientific study of parasites and the organisms that host them. There are several pathways through which pathogens can invade a host. The principal pathways have different episodic time frames, but soil has the longest ...

Allelopathic
Allelopathy is a biological phenomenon by which an organism produces one or more biochemicals that influence the germination, growth, survival, and reproduction of other organisms. These biochemicals are known as allelochemicals and can have beneficial (positive allelopathy) or detrimental (negative allelopathy) effects on the target organisms and the community. Allelopathy is often used narrowly to describe chemically-mediated competition between plants; however, it is sometimes defined more broadly as chemically-mediated competition between any type of organisms. Allelochemicals are a subset of secondary metabolites, which are not directly required for metabolism (i.e. growth, development and reproduction) of the allelopathic organism. Allelopathic interactions are an important factor in determining species distribution and abundance within plant communities, and are also thought to be important in the success of many invasive plants.

Canavalia Ensiformis
''Canavalia ensiformis'' (jack bean) is a legume which is used for animal fodder and human nutrition, especially in Brazil where it is called ''feijão-de-porco'' ("pig bean"). It is also the source of concanavalin A. Description ''C. ensiformis'' is a twining plant up to in height. It has deep roots, which makes it drought resistant. The plant can spread via long runners. The flowers are pink-purple in colour. The pods are up to long with large white seeds. Uses The plant is not in large-scale commercial cultivation. The beans are mildly toxic, and copious consumption should be avoided. Boiling will, however, remove toxicity if done properly. Young foliage is also edible. The whole plant is used for fodder, although it cannot be used in fodder mixtures containing urea, since it contains large quantities of the enzyme urease, which liberates harmful ammonia from urea. For this reason ''C. ensiformis'' has been investigated as a potential source of the urease enzyme. It ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
