Beet curly top is a disease of sugar beet which has been in the center of attention due to unpredictable epidemics and its economic importance. It has been shown that due to short life cycle and high populations of the leafhopper vector, the disease often spreads very rapidly in a region. least five virus species of the genus Curtovirus (Geminiviridae) are recognized as the cause of be curly top disease. Two of these species, namely, Beet severe curly top virus (BSCTV) and B curly top Iran virus (BCTIV) have been reported from Iran. Two leafhopper species, Circulif haematoceps and C. tenellus, have been reported as the vector of Beet curly top virus before recognition of different species. Therefore, it was not certain whether one or both viruses transmitted by the leafhoppers. Recently, it was shown that C. haematoceps could transmit BS from sugar beet plants infected via an infectious clone of the virus (Fattahi et aL, 2010). In present study, the possibility of transmission of BCTIV by C. haematoceps was exam Leafhoppers were collected in sugar beet fields of northern Fars province using D-Vac. T dominant species was C. haematoceps. The leafhoppers were allowed to breed on healthy sugar beet in the greenhouse. The newly born nymphs were placed on sugar beet plants previou agroinoculated with an infectious clone of BCTIV (Zarghan isolate) for an acquisition access pe of four days, and then transferred to healthy seedlings at 2-leaf stage (5 leafhoppers / 3 seedling Typical symptoms of curly top appeared on all inoculated seedlings after two weeks. Presenc BCTIV in symptomatic test plants was verified by PCR using specific BCTIV primers. experiment was repeated two more times with similar results. It is concluded that like BSCT BCT1V is transmitted by C. haematoceps under greenhouse condition. [ABSTRACT FROM AUTHOR] |
