Web1 Introduction. Caenorhabditis elegans (C. elegans) is one of the most heavily utilized model systems for elucidating the molecular mechanisms of organismal longevity and health span.Most of the pathways that have been found to affect aging, also affect fat metabolism, suggesting that a close connection exists between lipid metabolism and aging (Bitto et … WebC. elegans plays an essential role as a model organism in our understanding of biology and neuroscience.

These data indicate that physical pairing of the spo-11 extrachromosomal array with the endogenous spo-11 loci at the time of expression cannot be responsible for their ... At 20 °C, the laboratory strain of C. elegans (N2) has an average lifespan around 2–3 weeks and a generation time of 3 to 4 days. C. elegans has five pairs of autosomes and one pair of sex chromosomes. Sex in C. elegans is based on an X0 sex-determination system. Hermaphrodites of C. elegans have a … See more Caenorhabditis elegans is a free-living transparent nematode about 1 mm in length that lives in temperate soil environments. It is the type species of its genus. The name is a blend of the Greek caeno- (recent), rhabditis (rod-like) … See more The hermaphroditic worm is considered to be a specialized form of self-fertile female, as its soma is female. The hermaphroditic germline produces male gametes first, and lays eggs through its uterus after internal fertilization. Hermaphrodites produce all their See more The different Caenorhabditis species occupy various nutrient- and bacteria-rich environments. They feed on the bacteria that develop in decaying organic matter (microbivory). Soil lacks enough organic matter to support self-sustaining populations.
