Ageratum enation virus

Family   : Geminiviridae
Genus : Begomovirus
Acronym : AEV

Introduction

Ageratum enation virus (AEV) is virus belonging to the genus, Begomovirus. It is known to infect several hosts such as Calendula officinalis, Ageratum houstonianum, tomato, pointed gourd (Trichosanthes dioica), zinnia, cat's whiskers (Cleome gynandra L.), Crassocephalum crepidioides and grain amaranth (Amaranthus cruentus L.) causing leaf curl, leaf enation and stunting symptoms.
