dc.description.abstractPlant disease epidemics result from interactions of a susceptible host, a virulent pathogen and conducive environment. Shifts in any component can change disease expression to still unknown directions. Verticillium wilt (VW) of olive caused by the soilborne fungus Verticillium dahliae (Vd) is of major concern for olive industry in the Mediterranean basin. We carried out experiments using olive cvs. Picual and Arbequina, which grew in soil infested by the defoliating (D) or non-defoliating (ND) Vd pathotypes at 20, 24 and 28ºC and CO2 levels of 386, 550 and 750 ppm, representative of current and future SRES-IPCC A2 and B2 scenarios for southern Spain. Surface response models quantified the combined effects of temperature and CO2 on VW intensity and plant growth, demonstrating a differential effect of biotic and abiotic factors. Optimum VW development occurred at 20-24°C and current CO2, being faster and severe in 'Picual'/D. Raising CO2 delayed VW and Vd infection. The transcriptomic profile of olive cultivars in response to Vd infection and the three climate SRES scenarios was assessed using a 12-plex microarray of 37,449 olive unigenes (OLEAGEN project). Main differences in the expression profiles were due to olive genotype, followed by the climatic conditions at the three SRES scenarios and in a lesser extent by Vd infection. Thus, plants growing at current climate showed higher number of differentially expressed genes compared to plants growing at SRES-IPCC A2 and B2 scenarios with a general trend to decrease the number of significantly transcribed genes as temperature and CO2 increased. Furthermore, a higher number of genes (up to 10x) were expressed differentially in 'Arbequina' than in 'Picual' in response to environmental changes as well as to infection by the D pathotype with a low number of genes being common for both cultivars.es_ES
