Chilli leaf curl Vellanad virus

Family   : Geminiviridae
Genus : Begomovirus
Acronym : ChiLCVeV

Introduction

In December 2008, a chilli (Capsicum annuum) leaf curl disease incidence of up to 100% was recorded in Vellanad district of Kerala. The infected plants exhibited typical upward leaf curling, crinkling, puckering and reduction of leaf area, along with stunting of whole plants. Following sequencing, the virus was considered a new begomovirus species for which the name Chilli leaf curl Vellanad virus (ChiLCVeV) was given. The associated betasatellites each contain a single ORF C1 and they share maximum identity of 95.6 and 96.9% with Radish leaf curl betasatellite and Tomato leaf curl Bangladesh betasatellite, respectively. Thus ChiLCVeV, along with two distinct betasatellites (Radish leaf curl betasatellite and Tomato leaf curl Bangladesh betasatellite) are associated with chilli leaf curl disease in Vellanad, Kerala.
