Abstract: | Every year the consequences of water deficit on crop yield and quality are profound. The observation that many wild species
relatives of cultivated crops display a greater stress tolerance and the fact that the cultivated species generally display
only a fraction of the allelic diversity available within the tomato clade suggest that crossing of wild species with elite
cultivars could improve the stress physiology of modern crops. To assess this from the basis of chemical composition we applied
an established GC-MS based metabolite profiling method to fruits from irrigated and non-irrigated tomato plants either of
the cultivated tomato (Solanum lycopersicum) or of its hybrid with its wild species relative (Solanum pennellii). Results are discussed in terms of both the metabolic response to drought stress and the potential of utilizing exotic germplasm
as a means to improve agronomically important characteristics of crop species.
