Isoprenoid substances can help maintain
photosynthesis from being damaged by high leaf temperatures
and the recovery of photosynthesis can be increased
by the emission of monoterpenes after brief high temperature
episodes (Sharkey and Singsaas, 1995; Singsaas and
Sharkey, 1998). Therefore, plant terpenoids in general could
well be able to induce resistance to high temperature and
possibly also to other environmental stresses such as drought
(Sharkey and Loreto, 1993) and ozone (Loreto et al., 2004).
