FIG. 8.

(a1) Left Y axis 1: mean body length, Left Y axis 2: mean body diameter, right Y axis: Average force applied per pillar for different strains. Error bars are ±SEM (n ≥ 20 animals per strain). (a2) Average forces per pillar exerted by different body parts, namely, head, middle, and tail of the worm. Forces were measured for 5 worms of selected strains for 5 image frames each. Error bars are SEM for 5 animals per strain. (b1) and (b2) Dotted and dashed lines represent forces on the two selected pillars (anterior and posterior, respectively) near the centerline of D. melanogaster larva (left Y axis). Solid line represents the peristaltic contractions of the body wall muscles recorded as the major axis length of the body (right Y axis). (b1) shows forward crawling and (b2) shows reverse crawling.
