Characterization of a novel psyllid-transmitted waikavirus in carrots.

ABSTRACT: Carrots collected from the Western Negev region in Israel during the winter of 2019 showed disease symptoms of chlorosis, leaf curling, a loss of apical dominance, and multiple lateral roots that were not associated with known pathogens of the carrot yellows disease. Symptomatic carrots were studied for a possible involvement of plant viruses in disease manifestations using high throughput sequencing analyses. The results revealed the presence of a waikavirus, sharing a ∼70% nucleotide sequence identity with Waikavirus genus members. Virions purified from waikavirus-positive carrots were visualized by transmission electron microscopy, showing icosahedral particle diameter of ∼28 nm. The genome sequence was validated by overlapping amplicons by designed 12 primer sets. A complete genome seq
