Potyviridae

Discovery of novel members of the Potyviridae family reveals expanded diversity, a broad host range, and evidence of fungal and oomycete infections

The family Potyviridae represents the largest and most economically important group of plant-infecting RNA viruses. Despite extensive study of crop-associated members, the full diversity, host range, and evolutionary history of potyvirids remain poorly understood. Here, we conducted a large-scale mining of publicly available RNA-seq datasets to systematically search for novel potyvirid sequences.
