(a) Structures of ascr#1 and ascr#9. (b) SIM-HPLC-MS analyses showing molecular ion traces for ascr#1 (left) and ascr#9 (right) in exo-metabolome samples of females (F) and hermaphrodites (H). (c) Amount of ascarosides produced per worm of each sex. (d) Chemotaxis index of males towards synthetic ascr#1 and ascr#9. This graph represents the mean ± SEM of ten independent experiments with 15 males each.
