Fig. 3

Expression of Parasteatoda tepidariorum FoxB and odd-skipped (odd) in dissected limbs. Note that expression of FoxB is exclusively in ventral tissue in all investigated stages and appendage types (aj) [except for the labrum, l where expression is in dorsal tissue. See text for further explanation]. In a and di, the left photograph represents a lateral view, the right photograph shows a posterior view on the same appendage. b, c, l Anterior view. j Posterior view. k Lateral view. Note the appearance of segmental transverse stripes of enhanced expression within the ventral region of FoxB expression in the pedipalps and legs (e.g., e, i, j) co-expressed with odd (k). Arrows in k point to co-expression of odd and FoxB. cw claw, cx coxa, e endite, fe femur, mt metatarsus, pt patella, ti tibia, ta tarsus, tr trochanter
