Monoterpenes obtained from S. lycopersicum (M82) and S. pennellii (LA0716) plants and two isogenic chromosomal substitution lines and analyzed by GC-MS. (A) A leaf was dipped briefly in MTBE and the extract analyzed. (B) Type VI trichomes were collected by hand and placed into a vial containing MTBE. Numbered peaks are as follows: 1, δ-2-carene; 2, α-phellandrene; 3, α-terpinene; 4, limonene; 5, β-phellandrene; 6, γ-terpinene. No linalool was detected in any of the samples. Chromatograms show the detection of m/z = 93. Rt, retention time.
