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.
Sample Type:Plant

Treatment:

Treatment ID:TR002988
Treatment Summary:No specific treatment.

Sample Preparation:

Sampleprep ID:SP002985
Sampleprep Summary:After 40 hours of VOC trapping, Tenax cartridges were immediately subjected to thermal desorption.

MS:

MS ID:MS004447
Analysis ID:AN004700
Instrument Name:Agilent 5977B
Instrument Type:Single quadrupole
MS Type:EI
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.
