From: mab-31 and the TGF-β pathway act in the ray lineage to pattern C. elegansmale sensory rays
Sensory ray patterns of mutants in Sma/Mab pathway. Wild-type C. elegans male tail contains nine bilateral pairs of sensory rays (A and G). Their structural and neuronal (B type) processes were located by E1-GFP (D) and ppkd-2::gfp2 (J) markers, respectively. sma-6 (B and H) and mab-31 (C and I) mutants displayed rays 4-5 fusion (arrows) and rays 6-7 fusion (arrowheads) defects. In the defective rays, structural cell processes were fused (E and F), while the neuronal processes were separated (K and L). Ventral view. Scale bar = 20 μm.
