Abstract:

In order to determine whether Tomato brown rugose fruit virus(ToBRFV)occurs in Zhangjiakou and Yinchuan tomato producing areas,and to explore the genetic information and evolution of ToBRFV,so as to provide an important scientific basis for the diagnosis and control of ToBRFV and the genetic engineering of tomato resistance to viral diseases.Molecular detection was carried out in Zhangjiakou and Yinchuan suspected diseased fruits,and sequence analysis and genome-wide phylogenetic analysis of the virus gene were carried out by relevant molecular biology software.The results showed that the genome structure similarity between the virus isolates from Zhangjiakou and Yinchuan fruit was more than 99% similar to most of the ToBRFV isolates in GenBank,and the tomato fruit virus in the two places was determined to be ToBRFV.ToBRFV isolates were highly regional,and ToBRFV viruses from different regions of China were associated with many countries and regions from Europe and Asia,and the Zhangjiakou isolate was most closely related to the Chinese isolate(MT018320.1),and the Yinchuan isolate was clustered with the Peruvian isolate,indicating that the Yinchuan isolate may have originated from South America.The similarity of the four ORF amino acids of the Zhangjiakou isolate from China(MT018320.1)was the highest,while the similarity between the Yinchuan isolate and the Zhangjiakou isolate was low.In addition,this study found for the first time that the 444th base of the Yinchuan isolate CP protein changed from A to G,resulting in a meaningful mutation of the 131st amino acid of the CP protein from V(valine)to A(alanine).In summary,ToBRFV disease occurred in Zhangjiakou and Yinchuan tomato producing areas,and the virus came from different places in the two regions.
