Extended Data Figure 3: Ascarosides produced by wild-type strains.
From: Balancing selection shapes density-dependent foraging behaviour
a, b, LC–MS/MS analysis of ascarosides secreted by N2, CX12311 and MY14 strains grown on OP50 (a) or HB101 (b) bacteria. icas#9 is produced at similar levels by icas#9-sensitive and icas#9-resistant strains. n = 2 (a) or 3 (b) culture extracts per genotype.
