Figure 2. Collagens are required and sufficient to promote mate attractiveness.
(A) (Top) A schematic diagram of C. elegans cuticles (blue) with its surface coat (green) and furrow (arrow). Mutant hermaphrodites tested for mate recognition are listed below. (Bottom) The schematic diagram of the biosynthesis pathway of collagens and related mutants. (B-F) Percentage of male leavers in male retention assay with mutant hermaphrodites in indicated genotypes. (G) Quantification of body length in the dpy-7 temperature-sensitive mutants.
