In addition, in
the context of exploring the use of plants such as poplar
trees (Populus spp.) as a source for cellulose-based biofuels
(Doran-Peterson et al., 2008; Li et al., 2008; Pauly and
Keegstra, 2008), this paper will briefly address the apparent
loss of carbon from plants due to emission of volatile
terpenoid hydrocarbons, using the hemiterpene isoprene
(Figure 1) as an example.
