Abstract

A bipartite begomovirus isolate GD was isolated from Lycianthes biflora plants showing yellow mosaic symptoms in Nanxiong, Guangdong Province, China. The apparently full-length DNA-A and DNA-B viral components were cloned after enrichment of circular DNA by rolling circle amplification, restriction digestion, cloning, and DNA sequencing. The DNA-A component (2752nt, KT582302) shares highest (80.2%) nucleotide (nt) sequence identity with tomato leaf curl Sulawesi virus [Indonesia-Sulawesi-Langowan F101-2006] (ToLCSuV- [ID-Sul -LanF09-06], FJ237618), reported in Indonesia as causing yellow leaf curl disease of chilli pepper. The DNA-B component (2704nt, KT582303) shares highest (76.3%) nt sequence identity with pepper yellow leaf curl Indonesia virus-[Indonesia-tomato2-2005] (PepYLCIV-[ID-Tom2-05 AB213599) reported in Indonesia, and associated with yellow leaf curl disease in tomato. Based on the ICTV guidelines for begomoviral species demarcation, the virus is a new, previously undescribed bipartite begomovirus species for which the name “Lycianthes yellow mosaic virus” is proposed.
