Due to crowding, starvation or high temperature, their development can be sidelined to the dauer stage.
The principle chemosensory organ of these organisms is the amphid. The first transposon found in this organism was the founding member of the Tc1/mariner family and was found by analysis of the unc-54 gene. Two commonly studied strains of this organism are Bergerac and Bristol, and they are grown on NGM. Due to crowding, starvation or high temperature, their development can be sidelined to the dauer stage. This organism can be either XO or XX, corresponding to a male and self-fertilizing hermaphrodite, respectively. Mello and Fire discovered RNA interference in this organism, and it was also studied by Sydney Brenner. For 10 points, identify this nematode model organism, which was the first multicellular organism to have its genome sequenced.
