Metabolite levels across the 199 RILs and the two parental strains. (A) The average trait level of 19 AAs is first expressed as percentage of total AAs, followed by z-score transformation. The 199 RIL values are indicated in gray, the value of the parental strain N2 in orange, and the value of the parental strain CB4856 in blue. Trait levels below limit of quantification of AA measurement (0.4 nmol/mg of protein) are not shown. (B) The mean values of the levels of 44 FAs are shown after data transformation (the absolute FA concentration is expressed as a percentage over total FAs, followed by z-score transformation). The FA levels in 199 RILs are indicated in gray, those in the parental strain N2 and CB4856 are indicated in orange and blue, respectively. FA levels below limit of quantification of the measurement (0.03 nmol/mg of protein) are not shown.
