Hymenosides A-F, Six New Hemiterpene Glucosides from the Japanese Fern Hymenophyllum barbatum.

Chemical and Pharmaceutical Bulletin, 2001
In the course of investigation of the bitter-tasting substances of the Japanese fern Hymenophyllum barbatum belonging to the family Hymenophyllaceae, six new hemiterpene glucosides called hymenosides A-F (1-6) have been isolated from the methanol extract, together with an acyclic bis-bibenzyl derivative, perrottetin H.

The diversion of 2‐C‐methyl‐d‐erythritol‐2,4‐cyclodiphosphate from the 2‐C‐methyl‐d‐erythritol 4‐phosphate pathway to hemiterpene glycosides mediates stress responses in Arabidopsis thaliana [PDF]

The Plant Journal, 2015
Summary2‐C‐Methyl‐d‐erythritol‐2,4‐cyclodiphosphate (MEcDP) is an intermediate of the plastid‐localized 2‐C‐methyl‐d‐erythritol‐4‐phosphate (MEP) pathway which supplies isoprenoid precursors for photosynthetic pigments, redox co‐factor side chains, plant volatiles, and phytohormones.

Bacterial Degradation of tert-Amyl Alcohol Proceeds via Hemiterpene 2-Methyl-3-Buten-2-ol by Employing the Tertiary Alcohol Desaturase Function of the Rieske Nonheme Mononuclear Iron Oxygenase MdpJ [PDF]

Journal of Bacteriology, 2011
Tertiary alcohols, such as tert-butyl alcohol (TBA) and tert-amyl alcohol (TAA) and higher homologues, are only slowly degraded microbially. The conversion of TBA seems to proceed via hydroxylation to 2-methylpropan-1,2-diol, which is further oxidized to 2-hydroxyisobutyric acid. By analogy, a branched pathway is expected for the degradation of TAA, as
