Metabolic fate of the ingested aliphatic and indolic GLS in P. armoraciae adults that fed on leaves of different Arabidopsis lines for 5 days
| Mean percentage1 ± SD; N = 10 | ||||
|---|---|---|---|---|
| Metabolic fate | Aliphatic GLS wild type | Indolic GLS wild type | Aliphatic GLS cyp | Indolic GLS myb |
| Accumulation | 21.5 ± 5.3 | 8.2 ± 2.9 | 30.9 ± 7.3 | 27.1 ± 8.7 |
| Excretion | 13.6 ± 3.6 | 10.8 ± 3.8 | 9.5 ± 2.9 | 3.4 ± 0.6 |

1The amount of aliphatic and/or indolic GLS ingested from Arabidopsis wild type, myb, and cyp mutant, respectively, was set to 100%. The corresponding percentages of aliphatic and indolic GLS in adults (accumulation) and feces (excretion) were calculated. 2The total recovery corresponds to the recovered proportion of ingested GLS, which was detected in adults (accumulation) and feces (excretion). Aliphatic GLS: sum of 3MSOP GLS, 4MSOB GLS, 4MTB GLS, 5MSOP GLS, 7MSOH GLS, 8MSOO GLS; indolic GLS: sum of I3M GLS, 1MOI3M GLS, 4MOI3M GLS.
