Sesame curly top virus (sectv) is a new species in the genus turncurtovirus (family geminiviridae). to date, sesame was the only natural host of the virus. during a survey for identification of geminiviruses infecting crop, vegetable or ornamental plants in south-eastern iran, the sesame curly top virus infection of alfalfa, bean, eggplant, faba bean, blanket flower, radish and watermelon was confirmed by pcr and sequencing. the full-length genome of seven new sectv isolates share >97 and ~87-88% nucleotide identity with other sequences from iran and pakistan, respectively. an infectious clone of sectv was constructed, biolistically-or rhizobium-inoculated to several host plant species and the pathogenesis of the virus was demonstrated. results of this study indicated that, similar to known turncurtoviruses, sectv has a wide natural host range in iran and among the alternative hosts, the rate of infection and severity of disease in watermelon are remarkable.
