Description It was over half a century ago when the overwhelming array of chemicals found in plants was postulated to be more than
just by-products of primary metabolism. Ever since, extensive research has been conducted on plant secondary metabolites
which are now known to be the end points of sophisticated survival mechanisms that plants have developed as a response
to various kinds of stresses. Stress, defined by its negative effect on the growth and development of an individual, can be
internal (metabolic or genetic), external (biotic or abiotic), permanent or acute. To cope, organisms must develop tolerance,
resistance or avoidance mechanisms. Isoprenoids, often released as volatiles from plants, constitute the most diverse
groups of natural products and play an essential part in plant defense systems, both directly (as emitted volatiles) and
indirectly (the principle of inviting friends to feast on foes). Research over the last decade has resulted in a significant
improvement in our understanding of the isoprenoid biosynthesis but there remains much to learn about the complex
regulatory network controlling the various steps of these pathways and their dynamic co-ordination. Here we identify
novel plant proteins and provide a putative role for them in isoprenoid based stress responses, along with insights into
future perspectives for research.
