Photinini
The Photinini are a large tribe of fireflies in the subfamily Lampyrinae. ''Photinus pyralis'' is famous in biotechnology for its luciferase gene. This is sometimes employed as a marker gene; genetically modified organisms which contain it start to glow like the firefly when brought in contact with a luciferin-containing medium. Firefly luciferases differ slightly between taxa, resulting in differently colored light and other properties, and in most cases where "firefly luciferase" is used in some application or study, it is the specific luciferase of '' P. pyralis''. Systematics The group has recently been examined using molecular phylogenetics, using fairly comprehensive sampling.

Luciferase
Luciferase is a generic term for the class of oxidative enzymes that produce bioluminescence, and is usually distinguished from a photoprotein. The name was first used by Raphaël Dubois who invented the words ''luciferin'' and ''luciferase'', for the substrate and enzyme, respectively. Both words are derived from the Latin word ''lucifer'', meaning "lightbearer", which in turn is derived from the Latin words for "light" (''lux)'' and "to bring or carry" (''ferre)''.Luciferases are widely used in biotechnology, for bioluminescence imaging microscopy and as reporter genes, for many of the same applications as fluorescent proteins. However, unlike fluorescent proteins, luciferases do not require an external light source, but do require addition of luciferin, the consumable substrate. Examples A variety of organisms regulate their light production using different luciferases in a variety of light-emitting reactions. The majority of studied luciferases have been found in animals, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Lampyrinae
The Lampyrinae are a large subfamily of fireflies (Lampyridae). The exact delimitation, and the internal systematics, have until recently been a matter of debate; for long this group was used as a "wastebin taxon" to hold any fireflies with insufficiently resolved relationships. Regardless, they are very diverse even as a good monophyletic group, containing flashing and continuous-glow fireflies from the Holarctic and some tropical forms as well. The ancestral Lampyrinae probably had no or very primitive light signals; in any case several modern lineages appear to have returned to the pheromone A pheromone () is a secreted or excreted chemical factor that triggers a social response in members of the same species. Pheromones are chemicals capable of acting like hormones outside the body of the secreting individual, to affect the behavio ... communication of their ancestors independently.Stanger-Hall, Kathrin F.; Lloyd, James E. & Hillis, David M.

Photinus Pyralis
''Photinus pyralis'', known by the common names common eastern firefly and big dipper firefly, is the most common species of firefly in North America. ''P. pyralis'' is a flying and light-producing beetle with a light organ on the ventral side of its abdomen. This organism is sometimes incorrectly classified as ''Photuris pyralis'', which likely results from mistaking the similar-sounding genus ''Photuris''. The ''Photuris'' female may also lure a ''Photinus pyralis'' to be eaten to obtain spider-repellent steroids called "Lucibufagin, lucibufagins". In males the light organ covers the entire ventral surface of the three most posterior segments and in females it only covers a portion of the third posterior segment.Mast, S.O. 1912.

They were previously known under a variety of genera, including ''Photinus Photinus (Greek Φωτεινός; died 376), was a Christian bishop of Sirmium in Pannonia Secunda (today the town Sremska Mitrovica in Serbia), best known for denying the incarnation of Christ, thus being considered a heresiarch by the Catholic C ...''.
