Molecular markers reflect differentiation of Fusarium oxysporum forma speciales on tomato and forma on eggplant

► The present study is on genetic diversity and molecular markers. ► The genetic structure within Fusarium oxysporum infecting tomato and eggplant was investigated. ► The markers could be associated with genes encoding virulence proteins of the pathogens. ► The comparisons were done on genes encoding virulence and development proteins with ISSR sequences. ► Evaluation was done according to international databases considering E values.
