C elegans embryo development

In the last fifty years, the roundworm Caenorhabditis elegans has risen to become a top model organism for biological research. This tiny nematode is one of the simplest and easiest species to treat among laboratory animals. And its existence outside of the lab is beginning to be revealed. C. elegans, like other model species, has a boom-and-bust lifestyle. It eats ephemeral bacterial blooms that appear in decomposing fruits and stems. Its young larvae undergo a migratory diapause stage known as the dauer after resource depletion. Migration vectors (such as snails, slugs, and isopods) and pathogens are known to be associated with C. elegans (such as microsporidia, fungi, bacteria and viruses). We create a broader framework and improved tools for studying C. elegans biology by deepening our understanding of its natural history.
Caenorhabditis elegans, a free-living nematode, is a major model species used in a variety of biological studies. After early work on its mode of reproduction, meiosis, and evolution by Emile Maupas (Maupas, 1900) and Victor Nigon (Nigon, 1949; Nigon et al., 1960), studies by Sydney Brenner and collaborators in the 1960s and 1970s elevated C. elegans to the status of a premier model organism. Aside from its genome, which was the first to be sequenced for a multicellular organism (The C. elegans Sequencing Consortium, 1998), this organism’s genetic, cellular, developmental, and behavioral biology (The C. elegans Research Community) now has a large body of knowledge. C. elegans has been used to discover a variety of important items, including the molecular mechanisms of apoptosis (Conradt and Xue, 2005) and gene silencing by small RNAs (Grishok, 2013).

Caenorhabditis elegans (/sinorbdats lns/) is a form of Caenorhabditis.

[6]) is a 1 mm long free-living transparent nematode that lives in temperate soil environments. It is the genus’s type species. [eight] The name is a combination of the Greek words caeno- (recent) and rhabditis (rod-like)[9] as well as the Latin word elegans (elegant). Rhabditides elegans was the name given to it by Maupas in 1900. In 1952, Osche classified it as a subgenus of Caenorhabditis, and Dougherty elevated Caenorhabditis to the rank of genus in 1955. [nine]
C. elegans is a pseudocoelomate that does not have a respiratory or circulatory system.
[nine] The majority of these nematodes are hermaphrodites, with a few males thrown in for good measure. (12) Males have spicule-encrusted tails that they use for mating.
Sydney Brenner proposed C. elegans study in 1963, with a focus on neuronal growth. He started studying the molecular and developmental biology of C. elegans in 1974, and it has since become a widely used model organism. [13] It was the first multicellular organism to have its entire genome sequenced, and it is also the only organism whose connectome (neuronal “wiring diagram”) has been completed as of 2019.
