mig-6 class-l mutations reduce the rate of DTC migration. (A) Schematic of an adult C. elegans hermaphrodite: DTCs (green), distal gonad arms with no eggs (gray), proximal arms with eggs (gray ovals), spermathecae (red) and fertilized eggs (white ovals) are shown. (B) Images of gonad arms and DTC (arrows) relative to the vulva (triangle) of N2 (left panels) (in two focal planes for the adult) and class-l mig-6(oz113) (right panels) at mid-L3, mid-L4 and adult stages. Asterisks indicate posterior. Scale bars: 50 μm. Black bar applies to top four panels. (C) Lengths of anterior and posterior gonad arms of individual animals (from a partially synchronized population) are plotted against developmental stage, as determined by vulva shape. Rates of movement for mutants (grouped) and controls were obtained by the slope of the line, as determined by the least squares method.
