Caenorhabditis elegans (/ ˌ s iː n oʊ r æ b ˈ d aɪ t ə s ˈ ɛ l ə ɡ æ n s / [6]) is a free-living transparent nematode about 1 mm in length that lives in temperate soil environments. [7] It is the type species of its genus. [8] The name is a blend of the Greek caeno-(recent), rhabditis (rod-like) [9] and Latin elegans (elegant).
The genus Caenorhabditis contains the noted model organism Caenorhabditis elegans and several other species for which a genome sequence is either available or currently being determined. The two most-studied species in this genus ( C. elegans and C. briggsae ) are both androdioecious (they have male and hermaphrodite sexes) whereas most other ...
The nematode worm Caenorhabditis elegans was first studied in the laboratory by Victor Nigon and Ellsworth Dougherty in the 1940s, but came to prominence after being adopted by Sydney Brenner in 1963 as a model organism for the study of developmental biology using genetics.
For example, C. elegans dauer larvae can survive up to four months, much longer than their average lifespan of about three weeks during normal reproductive development. [7] Two genes that are essential for dauer formation are daf-2 and daf-23. [8] Dauer formation in C. elegans requires a nuclear receptor DAF-12 and a forkhead transcription ...
WormBase is an online biological database about the biology and genome of the nematode model organism Caenorhabditis elegans and contains information about other related nematodes. [1] [2] WormBase is used by the C. elegans research community both as an information resource and as a place to publish and distribute their results. The database is ...
WormBook is an open access, comprehensive collection of original, peer-reviewed chapters covering topics related to the biology of the nematode worm Caenorhabditis elegans (C. elegans). WormBook also includes WormMethods, an up-to-date collection of methods and protocols for C. elegans researchers. [1] [2] [3] [4]
Caenorhabditis elegans, a nematode, usually called C. elegans [24] - an excellent model for understanding the genetic control of development and physiology. C.elegans has a fixed number of 1031 cells. C. elegans was the first multicellular organism whose genome was completely sequenced
Worm bagging (also referred to as facultative vivipary or endotokia matricida) is a form of vivipary observed in nematodes, namely Caenorhabditis elegans. The process is characterized by eggs hatching within the parent and the larvae proceeding to consume and emerge from the parent. [1]
