Tomato leaf curl Kerala virus

Family   : Geminiviridae
Genus : Begomovirus
Acronym : ToLCKeV

Introduction

Tomato leaf curl disease (ToLCD) is a cause of concern for the tomato plant. This disease is mostly caused by leaf curl viruses of Geminiviridae family that include more than 50 species of Tomato leaf curl viruses of genus Begomovirus. Threat to the tomato crop is further aggravated by the high level of recombination observed in the geminiviruses during mixed infection resulting in the emergence of new and virulent viral species. Tomato leaf curl Kerala virus (ToLCKeV) is one such recombinant virus infecting tomato in Kerala.
