- maintenance of gene silencing variant
Animals differ from controls in the expression of genes targeted for silencing (gene inactivation) in subsequent generations via transcriptional or post-transcriptional processes.
- tail swelling
Swelling in the post anal region compared to control. In C. elegans this swelling can be associated with infection from the nematode-specific bacterial pathogen, Microbacterium nematophilum.
- synapse morphology variant
Animals display variations in the appearance of the subcellular junctional structure composed of a presynaptic terminal directly opposite the post-synaptic target and separated by a synaptic cleft.
- protein modification variant
Variations in the covalent alteration of one or more amino acids occurring in proteins, peptides and nascent polypeptides (co-translational, post-translational modifications), compared to control. This includes the modification of charged tRNAs that are destined to occur in a protein (pre-translation modification).
- precise vulval location variant
Any variation in the mating process that includes the male positioning his tail precisely over the vulva so that he may insert his spicules and ejaculate compared to control. In C. elegans precise vulva location (coordinating movement and tail positioning) requires the post cloacal sensillium and the spicules.
- tail morphology variant
Animals exhibit variations in the form, structure or composition of any portion of the most posterior region of the body compared to control. The anterior bound of the tail is not well defined though it might range from the position of the post-deirids to the opening of the anus (Wormatlas).
