Metabolomic approaches including Fourier- transform infrared (FT-IR) spectroscopy and Electrospray ionisation mass spectrometry (ESI-MS) were used to elucidate changes during susceptible and resistant interactions of Magnaporthe grisea with B. distachyon. Following data mining, discriminatory analytes (m/z) were shown to be phospholipids (PL) by ESIMS-MS. We are now moving to correlate transcriptional and metabolomic changes, concentrating on PL-based regulation.
This same Metabolomic approach is being applied to the Botrytis cinerea interaction with Arabidopsis wild-type and ethylene signalling mutants, which exhibit either enhanced or compromised defence.
We developed an automated sample preparation protocol based on a robotic platform PAL RTC (CTC Analytics AG, Zwingen Switzerland), which represent a modified Bligh and Dyer method producing samples for both hydrophilic metabolomics using GC-MS and lipidomics using SFC-MS simultaneously.READ MORE
