^aThe numbers correspond to the GC peaks marked in Figure 3. We numbered them according to the order of elution.

^bPutative identity of VCs present in the headspace of 3-day-old Trichoderma cultures is shown. Only the compounds that were present in two biological replicates are listed. Mass spectra and retention index of each compound were compared with reference data in the NIST library for identification.

^cLinear Retention Index (RI) of each compound determined using a mixture of alkane standards (C₇-C₄₀).

^dLinear RI of each compound found in the literature. – (Linear RI of these compounds are not available in the literature).

^e√ denotes the presence of each compound.
