Collection:
| Collection ID: | CO002972 |
| Collection Summary: | Root VOCs and soil VOCs were trapped as described here (Schulz-Bohm, et al, 2018, "Calling from distance: attraction of soil bacteria by plant root volatiles", The ISME Journal, 12(5), pp.1252-1262.). Briefly, 1 Tenax cartridge was fitted into the side arms of the glass pots in such a way that their opening was exposed toward the plant roots/soil. The other arm received a constant airflow from an aerator. VOCs were sampled for 40 hours and immediately analyzed by thermal desorption-gas chromatography‒mass spectrometry. |

| MS Comments: | Analysis was performed using MassHunter Qualified software to extract and integrate peat spectra to profile the root volatiles from WT and mutant lines. The data from only soil was considered as the blank and was subtracted from the rVOCs data. Compounds were identified by using the library NIST 2020 (Agilent Technologies, Palo Alto, CA, USA) with minimum hit count of 65. The compounds that were found to be present in at least two biological replicates out of three were taken into consideration for further analysis. |
