Genetic interactions between blmp-1 and the heterochronic genes lin-29, dre-1, and daf-12 in the timing of the DTC dorsal turn.

aPercentage of animals in which the posterior DTCs showed a wild-type, premature, or retarded dorsal turn. At least 50 worms were scored for each genotype. Only the data for the posterior DTCs are shown.bPosterior DTCs with a path-finding defect were seen in 3% of lin-29(n546); daf-12(rh61rh411) worms and 2% of dre-1(dh99);daf-12(rh61rh411) worms.cPosterior DTCs with no obvious dorsal phase II migration and with the reversal of migration direction in centripetal phase III movement were seen in 16% of blmp-1 (s71); lin-29(RNAi) and 26% of blmp-1(s71); daf-12(rh61rh41) worms. This defect may be caused by abnormal pathfinding or retardation in phase II and III migration.
