The liverwort Frullania tamarisci (L.) Dumort produces large amounts of terpenoids, among others the sesquiterpene alcohol tamariscol. Tamariscol has an earthy woody fragrance, and the use in perfurmes and production of it was patented in 1984. The microbial terpene synthase-like (MTPSL) enzyme FtMTPSL6 is shown to be responsible for the biosynthesis of tamariscol. FtMTPSL6 was obtained through RNA sequencing of wild growing F. tamarisci along with six other MTPSLs (FtMTPSL1-7). The biochemical activity was determined for three of them, and two others where metabolic active, but the product could not be identified. The three characterized enzymes are the tamariscol synthase (FtMTPSL6), copaene synthase (FtMTPSL1) and gurjunene synthase (FtMTPSL3). Thus, the biosynthesis of the economically attractive compound tamariscol is established, and this opens up for further exploitation of this molecule.

Natural products (NPs) constitute a significant source of active biomolecules widely used in medicine, pharmacology and cosmetics. However, NPs structural characterization has the drawback of their chemical instability during the extraction steps and their likely transformation during the analytical protocol. In particular, tamariscol and conocephalenol are two compounds largely used in the cosmetic industry for their odorant properties.

Frullania tamarisci is usually regarded as a polymorphic, holarctic-Asian liverwort species with four allopatric subspecies [subsp. asagrayana, moniliata, nisquallensis and tamarisci]. This hypothesis is examined using a dataset including sequences of the nuclear internal transcribed spacer region and the plastid trnL-trnF and atpB-rbcL regions of 88 accessions of F.

Contact sensitivity to plants containing 1 or more sesquiterpene lactones (SLs) is difficult to diagnose. The mixture of SLs (SL mix) has been shown to detect only about 60% of sensitized individuals. In order to improve the diagnosis of sensitization to plants containing SLs, we have tested a mixture of frullanolides contained in Frullania dilatata and Frullania tamarisci at 3 different concentrations (0.
