Summary
A novel Potato virus Y (PVY) isolate, HLJ-C-44, was identified in China. This distinct PVY recombinant exhibits unique symptoms and biological properties compared to other PVY strains.
Area of Science:
- Plant Pathology
- Virology
- Genomics
Background:
- Potato virus Y (PVY) causes significant economic losses in potato production worldwide.
- Mosaic symptoms in potato plants are indicative of viral infection, necessitating pathogen identification.
- Understanding PVY diversity is crucial for developing effective disease management strategies.
Purpose of the Study:
- To identify and characterize a distinct Potato virus Y (PVY) isolate from Northeast China.
- To determine the genomic and phylogenetic relationships of the novel PVY isolate.
- To investigate the biological properties and phenotypic response of the isolate in different hosts.
Main Methods:
- Collection and propagation of symptomatic potato samples from Harbin, Heilongjiang province.
- Serological analysis for PVY detection.
- Whole-genome sequencing, phylogenetic analysis, and recombination analysis.
- Biological assays in four potato cultivars and *Nicotiana tabacum*.
Main Results:
- A novel PVY isolate, designated HLJ-C-44, was identified, exhibiting mild mosaic and crisped leaf margins.
- Genomic analysis confirmed HLJ-C-44 as a PVY isolate belonging to the PVYN-Wi strain group.
- Recombination analysis revealed a unique pattern in HLJ-C-44, differing from other PVYN-Wi isolates.
- Biological assays demonstrated distinct phenotypic responses of HLJ-C-44 in potato cultivars and *N. tabacum*.
Conclusions:
- HLJ-C-44 represents a novel PVY recombinant with distinct biological characteristics.
- The findings highlight the genetic diversity and evolving nature of PVY populations.
- Further research is needed to understand the epidemiological implications of this novel PVY recombinant.

Subviral agents are infectious entities that resemble viruses but lack one or more viral components, such as a capsid or essential replication machinery. These agents include viroids, prions, and satellites, each possessing distinct structural and functional characteristics that influence their mode of infection and replication.Viroids are the simplest subviral agents, consisting of circular, single-stranded RNA molecules without a protein coat. They exclusively infect plants, relying entirely...

Cells are sometimes infected by more than one virus at once. When two viruses disassemble to expose their genomes for replication in the same cell, similar regions of their genomes can pair together and exchange sequences in a process called recombination. Alternatively, viruses with segmented genomes can swap segments in a process called reassortment.
