Forest virology is an underdeveloped field of study, with viruses affecting forest trees barely explored. Recent studies have just begun to investigate the presence of tree viruses using next-generation sequencing (NGS) analysis. In this study, using high-throughput NGS analysis, we identified pinus nigra virus 1 (PNV1) in Korean red pine (Pinus densiflora), which has not been previously reported in Korea. PNV1 is an unclassified DNA virus belonging to the Caulimoviridae family, carrying a double-stranded DNA genome. We found that the virus is distributed nationwide and even found in pollen, suggesting that it has a high potential for transmission via pollen. Together, our findings suggest that this newly identified Pinus virus may have spread widely through pollen and seed transmission.
