biofilm absent head
Animals can move thorough a lawn of bacterially produced biofilm without accumulating an enormous amount of biofilm on its nose. When C. elegans is exposed to certain bacteria (e.g., Y. pestis), a biofilm accumulates on a worm's head. The presence of this biofilm inhibits feeding by the worm, and thereby prevents growth.
transdifferentiation defective
The conversion of one differentiated cell type into another does not occur as it does in control animals. In C. elegans, the Y cell undergoes a dramatic redifferentiation from being a cell in of the rectum to a PDA neuron. This transdifferentiation requires the cell to withdraw from its established position, migrate, and then become a motor neuron.
excretory canal short
The structure made by the processes of the excretory canal cell is reduced in size compared to control. In C. elegans this is an H-shaped structure which extends almost the full length of the body on both sides of the animal, generally in contact with the lateral hypodermis and the pseudocoelom (Wormatlas).
excretory canals long
The structure made by the processes of the excretory canal cell is increased in size compared to control. In C. elegans this is an H-shaped structure which extends almost the full length of the body on both sides of the animal, generally in contact with the lateral hypodermis and the pseudocoelom (Wormatlas).
