Dll expression was detected before the limb bud was morphologically visible in amphipod pereonites (Hejnol and Scholtz, 2004; Browne et al., 2005), indicating that the function of Dll in early limb development is conserved among amphipod pereopods.
The in situ hybridization analysis indicated that the lmbr1 expression levels were coincident with the Q-PCR results in HH21, HH23 and HH24 stages, with the expression sites located in ectoderm of the limb buds.
These parasites burrow into the hindquarters of tadpoles where they interfere with limb development by physically rearranging the limb bud cells.
