Fig. 14From: Convergent evolution of saccate body shapes in nematodes through distinct developmental mechanismsHelicotylenchus sp. and Aphelenchus avenae have seam cell homologs. Lateral view DIC micrographs (left) and pseudocolor overlay (right) of a J4 molting stage Helicotylenchus sp. and b J2 stage A. avenae. In both species, seam cells were morphologically similar to C. elegans [10]. Scale bars, 10 µmBack to article page
