Abstract:

In this study,both tomato spotted wilt orthotospovirus(TSWV)universal primers and TSWV synthetic primers were used to detect the virus disease samples collected from parts of Chifeng,Inner Mongolia China,and the amplified sequences were analyzed. Then,the nucleotide sequence containing N gene amplified by using specific primers was sequenced for phylogenetic analysis. The results showed that TSWV was detected in all 18 tomato fruit samples. The phylogenetic analysis of sequences including 914 nt fragment containingN gene showed that TSWV tomato isolate from Inner Mongolia was more closely to isolates from Yunnan and Jiangsu. After sap inoculation,pepper showed the symptoms of chlorosis in leaf and dwarfing. TSWV was detected by RT-PCR on the symptomatic leaves of pepper. This is the first time to prove that TSWV is harmful to tomato by molecular methods in Inner Mongolia.

Key words: tomato, tomato spotted wilt orthotospovirus, RT-PCR, Inner Mongolia
