Abstract

First report of Citrus leaf blotch virus in Peony in the U.S.A.

Abstract

Double stranded RNA-enriched nucleic acids were extracted from a peony (Paeonia lactiflora) showing stunting and gnarled irregularities, symptoms typically associated with Lemoine's disease, from Arkansas and Oregon, USA, collected from nursery and garden settings in 2015 and 2016. The material was used as template for next generation sequence analysis. The causal pathogen was identified as Citrus leaf blotch virus (CLBV) based on various molecular analyses. This is thought to be the first report of CLBV infecting Paeonia spp.
