This overview compiles the actual knowledge of the biogenic emissions of some volatile
organic compounds (VOCs), ie, isoprene, terpenes, alkanes, alkenes, alcohols, esters …

Volatile compounds act as a language that plants use for their communication and
interaction with the surrounding environment. To date, a total of 1700 volatile compounds …

The terpenoids constitute the largest family of natural products; over 22,000 individual
compounds of this class have been described (Connolly and Hill, 1991), and the number of …

Insects select their hosts, but trees cannot select which herbivores will feed upon them.
Thus, as long‐lived stationary organisms, conifers must resist the onslaught of varying and …

Terpene cyclases catalyze the synthesis of cyclic terpenes with 10-, 15-, and 20-carbon
acyclic isoprenoid diphosphates as substrates. Plants have been a source of these natural …

Plants that contain high concentrations of the defense compounds of the phenylpropene
class (eugenol, chavicol, and their derivatives) have been recognized since antiquity as …

Abstract The cotton (+)-δ-cadinene synthase (CAD1), a sesquiterpene cyclase, catalyzes a
branch-point step leading to biosynthesis of sesquiterpene phytoalexins, including gossypol …

Terpenoids are the largest, most diverse class of plant natural products and they play
numerous functional roles in primary metabolism and in ecological interactions. The first …

In plants, two pathways are utilized for the synthesis of isopentenyl diphosphate, the
universal precursor for isoprenoid biosynthesis. The key enzyme of the cytoplasmic …

Roots of Panax ginseng, one of the most famous medicinal plants, contain various
phytosterols and bioactive triterpene saponins (ginsenosides). In P. ginseng, phytosterols …
