Virome Analysis of Lemon Plants with Vein Clearing Symptoms Reveals Mixed Infection of Citrus Vein Clearing Virus, Iris Domestica Betaflexivirus 1 and Hop Stunt Viroid.

ABSTRACT: Citrus yellow vein clearing virus (CYVCV) is the causative agent of the yellow vein clearing disease (YVCD), a worldwide and highly destructive disease in lemon (Citrus lemon) and sour orange trees (C. aurantium). The typical symptoms of vein clearing are believed to be associated with CYVCV infection in citrus, so virus-specific diagnostic systems are currently used to confirm infection. In the present study, virome analysis based on high-throughput sequencing (HTS) on a lemon plant showing YVCD revealed mixed infection of CYVCV, iris domestica betaflexyviridae 1 (IDBV), and hop stunt viroid (HSVd). This multiple infection was confirmed in other two lemon plants with similar symptoms using virus/viroid specific primers. This is the first report of IDBV in lemon. Through mole
