Robert Horvitz initially established the importance of caspases in apoptosis and found that the ced-3 gene is required for the cell death that took place during the development of the nematode C. elegans.

In recognition of his pioneering role in starting what is now a global research community that work on C. elegans, another closely related nematode was given the scientific name Caenorhabditis brenneri.

The nematode worm C. elegans, a commonly used model organism in genetics studies, has 29, 647 genes in its nuclear genome, of which 620 code for tRNA.

Such effects were provided with evidence in laboratory models of stress using the nematode C. elegans, and in rats in which Rhodiola effectively prevented stress-induced changes in appetite, physical activity, weight gain and the estrus cycle.

* WormWeb. org: Interactive Visualization of the C. elegans Neural Network-C. elegans, a nematode with 302 neurons, is the only organism for whom the entire neural network has been uncovered.

Netrin was first described in the nematode Caenorhabditis elegans in 1990, and named UNC-6, according to standard C. elegans naming protocol.

The Dauer state is given other names in the various types of nematodes such as ‘ diapause ’, ‘ hyperbobis ’, ‘ spring rise ’, but since the C. elegans nematode has become the most studied nematode, the term ‘ dauer stage ’ or ' dauer larvae ' is becoming universally recognised when referring to this state in other nematodes.

One branch of helminthology is the study of the nematode C. elegans, a popular model organism in biology.

The brain is small and simple in some species, such as nematode worms ; in other species, including vertebrates, it is the most complex organ in the body.

* The nematode worm Caenorhabditis elegans, like Drosophila, has been studied largely because of its importance in genetics.

Some nematode s are also carnivorous, for instance this Mononchidae eating another Mononchidae.

It is somewhat difficult to relate this finding to the mammal, however, because in the smaller organism there are many genes ( at least 37 in the nematode ) that are " insulin-like " or " IGF-1-like ", whereas in the mammals insulin-like proteins comprise only seven members ( insulin, IGFs, relaxins, EPIL, and relaxin-like factor ) and have apparently distinct roles with some but less crosstalk.

On the other hand, simpler organisms typically have fewer receptors ( only one known in the nematode ) and the roles of these other insulins are unknown.

Two of the most commonly studied model organisms are invertebrates: the fruit fly Drosophila melanogaster and the nematode Caenorhabditis elegans.

Inquiries about the DNA of organisms are classed as genetic models ( with short generation times, such as the fruitfly and nematode worm ), experimental models, and genomic parsimony models, investigating pivotal position in the evolutionary tree.

By contrast, the nematode worm Caenorhabditis elegans has just 302 neurons making it an ideal experimental subject as scientists have been able to map all of the organism's neurons.

Nociception has been documented in non-mammalian animals, including fishes and a wide range of invertebrates, including leeches, nematode worms, sea slugs, and fruit flies.

However, at least one wild potato species, Solanum fendleri, is found as far north as Texas and used in breeding for resistance to a nematode species that attacks cultivated potatoes.

The potato root nematode is a microscopic worm that thrives on the roots, thus causing the potato plants to wilt.

Vinegar eels ( Turbatrix aceti ), a form of nematode, may occur in some forms of vinegar unless the vinegar is kept covered.

Rice pests include weeds, pathogens, insects, nematode, rodents, and birds.

Some nematode species such as Pratylenchus spp.

Many model systems have been developed to better understand interactions between plants and bacterial, fungal, oomycete, viral and nematode pathogens.

Caenorhabditis elegans () is a free-living, transparent nematode ( roundworm ), about 1 mm in length, which lives in temperate soil environments.

* Caenorhabditis elegans, a nematode worm species extensively used as a model in developmental biology

The most used invertebrate species are Drosophila melanogaster, a fruit fly, and Caenorhabditis elegans, a nematode worm.

A report investigating the inheritance of resistance to viral infection in the nematode Caenorhabditis elegans suggests that small RNA molecules may be inherited in a non Mendelian fashion and provide resistance to infection.

Organisms that show an intermediate level of codon usage optimization include Drosophila melanogaster ( fruit fly ), Caenorhabditis elegans ( nematode worm ) or Arabidopsis thaliana ( thale cress ).
