M lineage variant

The descendants of the M precursor cell exhibit variations in developmental programs compared to their counterparts in control animals. In C. elegans the M lineage is a postembryonic mesodermal lineage.

cell cycle arrest

Cells of the animals cease during one of its replicative phases (G1, S, G2, M).

early exit cell cycle

Cells leave the M phase (mitosis and cytokinesis) at an earlier time than sister or other control cells.

male sex muscle morphology variant

Any variation in the form, structure or composition of the muscles of the adult male reproductive system compared to control. In C. elegans males, the M myoblast gives rise to a much larger set of specialized muscles, compared to hermaphrodites, which differentiate within the tail region (Wormatlas).

hermaphrodite sex muscle morphology variant

Any variation in the form, structure or composition of the muscles of the adult hermaphrodite reproductive system compared to control. In C. elegans hermaphrodites these muscles include the vulval and uterine muscles, located near the vulva in the midbody, which all derive from the M myoblast (Wormatlas).

male M lineage variant

The descendants of the M precursor cell in male animals, exhibit any variation in developmental programs compared to their counterparts in control animals.

G2 checkpoint variant

Mitotic cells exhibit variations during the passage through a cell cycle control point late in the G2 phase of the mitotic cell cycle just before entry into M phase, nuclear division, compared to control cells.

plugged excretory pore

Males receive copulatory plugs from other males, deposited on their excretory pores. This phenotype is polymorphic among C. elegans strains and also in C. briggsae.

sodium acetate chemotaxis defective

Failure in directed movement in response to sodium acetate. In C. elegans, sodium acetate is an attractant. Sodium acetate has also subsequently been used to assay for Na+ attraction in C. elegans.

ammonium chloride chemotaxis defective

Failure in directed movement in response to ammonium chloride compared to control. In C. elegans, NH4Cl is an attractant. NH4Cl has also subsequently been used to assay for Cl- attraction in C. elegans.
