- temperature induced dauer formation variant
Animals exhibit variations in the entry into the dauer stage when exposed to temperatures that induce dauer formation in control animals. In C. elegans, many Daf-c animals enter dauer at 25C, whereas Hid animals enter dauer at 27C.
- octanol chemotaxis defective
Failure to execute the characteristic response to 1-octanol as defined by control animals. In C.elegans 1-octanol is typically a repellant.
- excretory secretory system morphology variant
Variations in the form, structure or composition of related tissues that allow the animal to secrete saline fluid and maintain a proper salt balance compared to control. In C. elegans, four cell types (1 pore cell, 1 duct cell, 1 canal cell and a fused pair of gland cells) make up the excretory system (Wormatlas).
- octopamine metabolism variant
Animals exhibit variations in any chemical reaction or pathway involving octopamine, 1-(p-hydroxyphenyl)-2-aminoethanol, compared to control.
- X chromosome nondisjunction
The frequency of sex chromosome segregation is perturbed, resulting in the production of exceptional gametes (e.g. ova or sperm) and populations with a sex ratio altered from the rate of 1:500 as observed for control populations.
- RME-1 recycling endosome localization variant
Any variation in the subcellular localization of membrane bound organelles, known as recycling endosomes, positive for the endocytosis protein RME-1, that traffic material from early endosomes back to the plasma membrane of the cell, thereby recycling recently endocytosed material to be reused at the plasma membrane.
- RME-1 recycling endosome morphology variant
Any variation in the form or composition of membrane bound organelles, known as recycling endosomes, positive for the endocytosis protein RME-1, that traffic material from early endosomes back to the plasma membrane of the cell, thereby recycling recently endocytosed material to be reused at the plasma membrane.
