Tapping panel dryness (TPD) is a complex disorder that causes partial or complete cessation of latex drainage upon tapping of rubber trees (Hevea brasiliensis). In this work, we determined the complete genome sequences of a novel virus identified in a rubber tree with TPD syndrome in China. The genome of the virus consists of 6811 nt and possesses two overlapping open reading frames (ORF1 and ORF2), encoding a polyprotein and a movement protein, respectively. The polyprotein shares 37% amino acid sequence identity with cherry virus A (CVA, ARQ83874.1) over 99% coverage. The genome architecture is similar to that of members of the genus Capillovirus (family Betaflexiviridae). Phylogenetic analysis of the replicase proteins showed that the virus clustered together with members of the genus Capillovirus. The new virus is tentatively called "rubber tree virus 1" (RTV1). RTV1 is the first virus reported to infect rubber trees. This work lays a foundation for research into finding the potential causal agent of TPD in Hevea brasiliensis.
