Genomic diversity of Capillovirus uniheveae (Betaflexiviridae) infecting Hevea brasiliensis Muell. Arg. in Hainan, China.

ABSTRACT:

Background

Rubber tree (Hevea brasiliensis Muell. Arg.) is a significant commercial crop in tropical areas worldwide, with rubber production threatened by Tapping Panel Dryness (TPD). Rubber tree virus 1 (Capillovirus uniheveae; RTV1) was identified in rubber tree samples with TPD symptoms through RNA-seq. However, its genetic diversity may have hindered the detection of RTV1 via RT-PCR, complicating the further identification of RTV1 as the causative agent of TPD. To assess RTV1 prevalence and genomic diversity, rubber tree bark samples with TPD syndrome were collected from various sites in Hainan, China, for RNA-seq and RTV1 genome determination.

Results

Twenty complete RTV1 genomes were determined from 22 samples with TPD syndrome via RNA-seq and RT-PCR. Using degenerate
