| Study Title | Detection of Methyl jasmonate (MeJA) in Plant root VOCs |
| Study Summary | Methyl jasmonate (MeJA) is a well-known plant hormone known for plant defense and plant-plant signaling. However, most of the studies are focussed on its aboveground presence and functions. Here we report that MeJA is also released by plant roots in a volatile form. More importantly, it is shown in Arabidopsis growing in natural conditions in soil. |

| Chromatography Summary: | Sample preparation and injection were performed using the fully automated Gerstel MPS-2 autosampler and Gerstel MAESTRO software. Volatile compounds were adsorbed on a Tenax TA tube. A thermal desorption unit (TDU) was used to thermally desorb the volatiles in splitless mode at 230°C for 10 min. To ensure that the volatiles released from the TDU were quantitatively trapped, a cooled injection system-programmed temperature vaporizer (CIS-PTV) was used. The CIS was heated from 80°C to 230°C at a rate of 12°C/s with the split valve closed during sample injection into the GC inlet. Analyses of volatile compounds were performed on an Agilent 7890B GC coupled to a 5977B quadruple mass spectrometer. Separation of compounds was performed on a DB-FFAP column (60 m x 250 µm x 0.25 µm, Agilent Technologies, Middleburg, OI, USA). Helium was used as the carrier gas at a flow rate of 1.9 ml/min, and solvent vent mode was used. The inlet temperature was 250°C. The oven program was as follows: initial temperature of 50°C held for 1 min, increased to 230°C at the rate of 10°C/min and held for 20 min. The temperature of the ion source and transfer line was 250°C. |
