Chemical Profiles of M. polymorpha Grown Axenically in Tissue Culture Conditions and in Soil under Greenhouse Conditions over a Developmental Time Course.

Organic extracts prepared from thallus material (or gemma for 0 months) collected at the indicated time points were profiled by GC-MS and the indicated peaks identified by reference to the NIST (2011) library and compound identifications according to Suire et al. (2000). Peaks 1 to6 correspond to d-limonene, (−)-α-gurjunene, (−)-thujopsene, β-chamigrene, β-himachalene, and (+)-cuparene, respectively. The dominant peak at ∼34 min was identified as phytol based on MS comparisons to NIST standards. IS, internal standard; S, sterile; NS, not sterile.
