Impatiens necrotic spot virus( INSV) is an important plant virus identified in recent years. Western flower thrip( Frankliniella occidentalis) has been confirmed to be the most efficient vector for INSV. In the present study,Illumina's second-generation sequencing technique was used to determine the variation in gene expression at the transcriptome level in western flower thrip before and after infection with INSV. By aligning 168 188 unigenes of western flower thrip to the NCBI protein database,47 558 unigenes were annotated,accounting for 28. 27% of the total. Species classification revealed that 58. 7% of the annotated unigenes of western flower thrip did not match any other species,and 15. 4% of had a match in Zootermopsis navadensis,12. 4% in Mus musculus,7. 3% in Mustela putorius,3. 4% in Theileria parva,and 2. 7% in Tribolium castaneum. By analyzing DEGs between INSV-free and INSV-carrying western flower thrips,we found that 11 genes were upregulated,and 9 genes were downregulated in western flower thrip after INSV infection. In addition,cell cycle and ubiquitin-proteasome pathway in western flower thrip were significantly infected by INSV infection.
In the present study, Illumina's second-generation sequencing technique was used to detect the presence of anaphylactoid virus (INSV) in an important plant virus identified in recent years. determine the variation in gene expression at the transcriptome level in western flower thrip before and after infection with INSV. By aligning 168 188 unigenes of western flower thrip to the NCBI protein database, 47 558 unigenes were annotated, accounting for 28. 27% of the total 4% of the annotated unigenes of western flower thrip did not match any other species, and 15.4% of had a match in Zootermopsis navadensis, 12.4% in Mus musculus, 7.3% in Mustela putorius, 3.4% in Theileria parva, and 2.7% in Tribolium castaneum. By analyzing the DEGs between INSV-free and INSV-carrying western flower thrips, we found that 11 genes were upregulated, and 9 genes were downregulat ed in western flower thrip after INSV infection. In addition, cell cycle and ubiquitin-proteasome pathway in western flower thrip were significantly infected by INSV infection.
