Abstract: In order to determine the occurrence and variation of Tomato spotted wilt virus (TSWV)in chrysanthemum in Beijing,we collected suspected chrysanthemum plants and performed molecular detection and partial genome sequence analysis. Sequences of RNA-dependent RNA polymerase(RDRP),glycoprotein(Gn-Gc),movement protein(NSm),non-structural protein(NSs),and coat protein(N)encoded by the virus were determined. Phylogenetic analysis showed that the isolate named Beijing-jh was most closely related to TSWV isolates of Spain and South Korea and was far related to TSWV isolates from China. The similarity analysis showed that the N gene was the most conservative gene. The average similarity of nucleic acids was 97.2%,the protein was 98.6%. The RDRP had the greatest variability,the average similarity of nucleic acids was 95.4% and the protein was 96.8%. The amino acids of the five proteins of TSWV from Beijing-jh isolate were the most similar to those from Spain. It is initially shown that Beijing-jh isolate was imported through international trade.
