Reveals viral infection in Panax notoginseng, indicating significant implications for its cultivation and health.

To identify and confirm the presence of bidens mottle virus (BiMoV) in Panax notoginseng and understand its impact.
Conducted field observation of symptomatic plants in Yunnan Province, China.
Collected leaf tissues from symptomatic and asymptomatic plants for analysis.
Applied transmission electron microscopy to identify viral particles.
Utilized high-throughput sequencing for RNA analysis to identify viral sequences.
Confirmed infectivity through sap inoculation in healthy seedlings.
Identified flexuous filamentous particles consistent with potyvirus in symptomatic plants.
Sequenced the full-length genome of BiMoV, showing 97.4% identity with other BiMoV isolates.
Confirmed successful infection in healthy seedlings, displaying typical symptoms by 14 days post-inoculation.
First documented instance of BiMoV infection in Panax notoginseng in China.
