Papaya leaf crumple virus

Family   : Geminiviridae
Genus    : Begomovirus
Acronym  : PaLCrV

Introduction

Papaya showing symptoms of leaf curl disease showed involvement of three distinct begomoviruses. One group resembled chili leaf curl virus infecting tomatoes (ChiLCuV), another group resembled tomato leaf curl New Delhi virus (ToLCuNDV) while the third group was novel which was named Papaya leaf crumple virus (PaLCrV). Associated most DNA β sequences resembled tomato leaf curl virus-associated DNA ?s. A few DNA β sequences were similar to that of croton yellow vein mosaic virus-associated DNA β (CroYVMVβ). One DNA β sequence was novel and showed <65% similarity to its counterparts. The PaLCrV was also naturally infects soybean and Golden Duranta (Duranta erecta).

Host Range and Symptomatology

Host	Symptoms
Papaya	Leaf curl
Golden Duranta (Duranta erecta)	Leaf curl, severe stuning with apical leaf curling and crinkled leaves.
Soybean	Yellow mosaic on leaves and leaf crumpling and distortion symptoms. Severely infected plants were stunted and bore less number of flowers and pods.
