- 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.
- 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.
- M line variant
Animals exhibit variations in the form, structure or composition of a planar structure within the muscle sarcomere which lies midway within the thick filament (A) band, attaching to the plasma membrane at its base and running up towards the inward surface of the myofilament lattice, compared to control animals (Wormatlas).
- M line absent
Animals lack the planar structure within the muscle sarcomere which lies midway within the thick filament (A) band, attaching to the plasma membrane at its base and running up towards the inward surface of the myofilament lattice, compared to control animals (Wormatlas).
- 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.
- 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.
- 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 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).
