Breeding for drought-tolerant crops is a pressing issue due to the increasing frequency and duration of droughts caused by climate change. Although important sources of variation for drought tolerance exist in wild relatives, the mechanisms and the key genes controlling tolerance in tomato are little known. The aim of this study is to determine the drought response of the tomato wild relative  Solanum pennellii  ( Sp ) compared with the cultivated tomato  Solanum lycopersicum  ( Sl ). The paper investigates the physiological and molecular responses in leaves of  Sp  and  Sl  plants without stress and moderate drought stress. Significant physiological differences between species were found, with  Sp  leaves showing greater ability to avoid water loss and oxidative damage. Leaf transcriptomic analysis carried out when leaves did not as yet show visual dehydration symptoms revealed important constitutive expression differences between  Sp  and  Sl  species. Genes linked to different physiological and metabolic processes were induced by drought in  Sp , especially those involved in N assimilation, GOGAT/GS cycle and GABA-shunt. Up-regulation in  Sp  of genes linked to JA/ET biosynthesis and signaling pathways was also observed. In sum, genes involved in the amino acid metabolism together with genes linked to ET/JA seem to be key actors in the drought tolerance of the wild tomato species.
