Abstract
  • Selective pressure induces pathogens to change their method of infection and, sometimes, causes species to become infectious. Pathogenic fungi must differentiate different morphological and physiological properties during the process of host specialization in their life cycle. In the present study, we conducted a genetic investigation and compared similarities within a generation of Fusarium oxysporum forma speciales (f. sp.) infecting tomato and forma (f.) infecting eggplants using selected ISSR and RAPD markers, two horticultural commodities belonging to the same taxon of the Solanaceae. Interestingly, genetic data showed that fungi belonging to F. oxysporum f. sp. infecting tomato have a close genetic relationship with the fungi f. infecting eggplant. Furthermore, F. oxysporum f. sp. infecting tomato showed less genetic variation than F. oxysporum f. melongenae, suggesting that it could be developed more recently during host adaptation. On the other hand, the gene sequence of inter-simple sequence repeat (ISSR) markers resulting in high polymorphism showed matches with gene sequences encoding specific proteins related to pathogenicity of F. oxysporum species. These findings support the notion that selected ISSR markers can be used to follow host-associated divergence of F. oxysporum species infecting tomato and eggplant and that differentiation of their specific genes can also be related to pathogenicity and development as predictive studies before initiating detailed sequencing analysis.
