mgDf90 completely eliminates the daf-3 coding region.

Slow pumping. Egg laying defective. Low frequency of dauer formation. Residual serotonin immunoreactivity, rare and very faint (<1% of NSMs) in most stages, but nearly 100% of CP neurons in adult males show faint to moderate serotonin immunoreactivity. Males mate quite well (E. Hare and C. Loer).

See MT15434 for a strain carrying mg280 without the cam-1 mutation.
