Movie S17.

Polarizing flows in an ect-2(gf); mlc-4(RNAi) embryo producing NMY-2::GFP: Cortical plane of an ect-2(gf) zygote on mlc-4(RNAi) producing endogenously labeled NMY-2 (NMY-2::GFP) imaged during polarizing flows with 5 second time intervals. Cortical flow speed is reduced when compared to ect-2(gf) mutants on RNAi control but is still strongly counter-rotating.
