| Abstract: | Tomato chlorosis virus (ToCV) is a plant virus that is mainly propagated by Bemisia tabaci in a semi-persistent and non-circulative manner.It has a wide range of host plants,and has been reported in many countries,causing serious economic losses in vegetable production.In 2019,we investigated about 10 fields,one ha each in Shouguang,Shandong province (China),and in each field we observed symptoms of interveinal chlorosis on lower leaves of the Solanum torvum Swartz,and a large number of B.tabaci gathered on the back of its leaves.To determine the presence of ToCV,total RNA of S.torvum was extracted followed by RT-PCR.The 1 074 (GenBank accessions number MN545620) and 466 bp (GenBank accessions number MN545621) fragments were gel purified and sequenced.The sequences shared 99.44% and 99.57% similarity with ToCV reference sequence tomato chlorosis virus segment RNA1 (AY903447) and RNA2 (AY903448).The results of insect transmission test confirmed that ToCV can spread from S. torvum to tomato.This study confirms S.torvum as a newly reported host of ToCV. |
