Uncovering Organosulfur Natural Products In The "Shy-Plant" Mimosa Pudica Via Direct Analysis In Real Time Mass Spectrometry : Volatiles Emission From Touch Sensitive Roots, Max Jacob Maron

Legacy Theses & Dissertations (2009 - 2024)

Mimosa pudica L. (Mimosaceae) is a small shrub endemic to South America, now pantropically distributed. M. pudica displays the properties of seismonasty where the leaves fold and stems droop in response to both touch, as well as nyctinasty, a type of circadian rhythm. It was previously reported that the principal component of the odor that is produced when M. pudica is uprooted is caused by CS2 and COS, both of which were detected by GC-MS. The present study has found that the roots emit a foul odor in response to direct root stimulation. Further, neither CS2 nor COS were observed …
