Virus… or stress? Diagnosis is one of the real challenges in plant health research.
Sometimes, the hardest part isn’t finding the virus, it’s proving whether there is one at all.

Oxford nanopore sequencing as a useful tool for investigating the population dynamics of invasive begomoviruses in Sicily Tomato yellow leaf curl disease is a major viral disease severely affecting tomato crops in the Mediterranean region, leading to reduced crop yield and significant economic losses. The disease is caused by monopartite begomoviruses belonging to the Geminiviridae family, primarily tomato yellow leaf curl Sardinia virus (TYLCSV) and tomato yellow leaf curl virus (TYLCV), which often co-infect tomato plants, promoting the emergence of recombinant viral genomes. To investigate the diversity and evolutionary dynamics of these viruses, symptomatic plants collected from agricultural sites in Sicily between 2020 and 2022, along with archived plant samples from 1994 to 1999, were analysed. For each collection site, leaves from symptomatic plants were pooled to form representative samples. Total nucleic acids were extracted and subjected to rolling circle amplification to enrich circular viral genomes. The amplified products were sequenced using Oxford Nanopore Technologies (ONT) long-read sequencing to obtain full-length viral genomes. Bioinformatic analyses revealed that archived samples mainly contained TYLCSV-related sequences, confirming its historical predominance in Sicilian agroecosystems. Recent samples, by contrast, were dominated by TYLCV-derived recombinants such as TYLCV-IS141- and TYLCV-IS76-like variants, indicating a temporal shift in the structure of the viral population. Furthermore, a distinct group of newly emerged recombinants, provisionally referred to as TYLCV-IMS54, was identified in the most recent samples. Their genome comprises a TYLCV backbone, a 54-nt segment from TYLCSV located downstream of the stem-loop region and a 341-nt region derived from TYLCV-Mild. These results demonstrate the importance of continuous viral population monitoring through ONT-based sequencing to detect emerging variants that may influence disease management strategies in tomato crops and highlight the central role of recombination in shaping begomovirus populations.

Oxford Nanopore long-read sequencing reveals temporal shifts in invasive begomovirus populations in Sicily, highlighting recombinant variants driving epidemic dynamics in tomato crops. #geminivirus #Nanopore #PlantVirology #tomato

RNA viruses are famous for their fast and sloppy replication, using error-prone RNA polymerases that generate lots of mutations. But here’s the twist: many DNA viruses mutate just as much — even though they often rely on the host’s supposedly “accurate” DNA polymerases. But why?
#PlantVirology

With HTS, we can detect even the smallest traces of viral RNA or DNA in plant samples—but not everything detected actually infects the plant.

Detection ≠ infection. HTS is just the start—validation is essential.

As global temperatures rise, insect vectors like whiteflies can increasingly shift their range. Regions once considered too cold may soon become suitable habitat—bringing plant viruses (and other pathogens) along for the ride.
