Abstract
Current climatic models forecast an increase of 1.5-4.0ºC in annual average temperatures over the next one hundred years, together with disturbances in the annual rainfall regime. All these models agree in pointing out the Mediterranean basin as one of the most potentially dramatically affected areas. Decrease of annual rainfall is expected in this region, together with an increase, in depth and duration, of seasonal drought. In this scenario, understanding of the molecular and physiological basis of drought stress response in Mediterranean forest species is of the utmost importance. Our model species, maritime pine (Pinus pinaster Ait.), is one of the most common conifer species in the Western Mediterranean, profusely used for afforestation in the Iberian Peninsula due to its frugality and ecological amplitude. Notwithstanding its relatively reduced geographical range, the species is adapted to a wide range of ecological conditions, particularly in relation with rainfall regimes and water availability. In this work we have identified genes induced by water stress in maritime pine grown in hydroponic culture. We have constructed and screened subtractive cDNA libraries (SSH). The putative function of selected genes has been determined by homology with available sequences in public databases (GenBank, NCBI). The expression pattern of the selected genes, both during the PEG-induced water stress and during a drought treatment on soil is analysed using specific microarrays
