	Caenorhabditis elegans - Wikipedia, the free encyclopedia
		Caenorhabditis elegans (pronounced see-no-rab-DYE-tis) is a free-living nematode (one of the roundworms), about 1 mm in length, which lives in a temperate soil environment.
		elegans is vermiform, bilaterally symmetric, with a cuticle integument, no segmentations, with four main epidermal cords and a fluid-filled pseudocoelomate cavity.
		In both sexes, a large number of additional cells (131 in the hermaphrodite, most of which would otherwise become neurons), are eliminated by programmed cell death (apoptosis).

		As a model organism for isolating and understanding the functions of genes controlling male tail form, we use Caenorhabditis elegans, also a member of family Rhabditidae.
		elegans is rounded (PELODERAN) at the tip, a form that is due to a morphogenetic event in the last larval stage in which the tail tip cells fuse together and change shape.
		To identify the components and regulatory networks governing the developmental process of morphogenesis, we screen for mutations that fail in male tail tip morphogenesis.

		The plasticity of dopamine-mediated behaviors, for example, habituation and sensitization, are not well understood at the molecular level.
		We show that in the nematode Caenorhabditis elegans, a D1-like dopamine receptor gene (dop-1) modulates the plasticity of mechanosensory behaviors in which dopamine had not been implicated previously.
		Selective expression of the dop-1 gene in mechanosensory neurons using the mec-7 promoter rescues the mechanosensory deficit in dop-1 mutant animals.
